The specification parameters of Thw-Ls Aluminum Building Wire are carefully designed to fully meet the diverse needs of building electrical systems and provide reliable guarantees for electricity use in different scenarios.

The wire diameter range of this wire covers 10-4 AWG, and different wire diameters correspond to different performances and applicable scenarios. The 4 AWG wire diameter is relatively thick, with a conductor cross-sectional area of approximately 21.15mm². The DC resistance at room temperature is not greater than 0.823Ω/km, and the current-carrying capacity can reach about 70A. It can easily carry the continuous high-load current of large electrical appliances such as air conditioning units and elevators. Therefore, it is suitable for scenarios with high requirements for current carrying, such as building main incoming lines and centralized power supply circuits for high-power equipment. The 10 AWG wire diameter is relatively thin, with a conductor cross-sectional area of about 5.26mm², a DC resistance of no more than 3.28Ω/km, and a current-carrying capacity of about 30A. It is suitable for branch circuits, such as lighting systems and ordinary sockets in low-power consumption areas, which can accurately match the electricity demand of these areas, avoiding resource waste caused by "using a large material for a small purpose" or overload risks caused by "using a small material for a large purpose".

In terms of rated voltage, the wire reaches 600V, which far exceeds the common 220V/380V power distribution standards in residential and commercial buildings. The higher rated voltage provides a sufficient safety margin for voltage fluctuations. Even if the grid voltage rises instantaneously, the wire can still operate stably without aging or damage to the insulation layer due to voltage problems, ensuring the normal power supply of the building electrical system.

In addition, the insulation thickness of the wire also varies according to the wire diameter. The insulation thickness of 4 AWG wire is about 1.5mm, and that of 10 AWG wire is about 0.8mm. This design is to ensure that the insulation layer can effectively play its insulating role under different wire diameters and prevent electric leakage accidents. At the same time, the outer diameter of the wire also changes with the wire diameter. The outer diameter of 4 AWG wire is about 10mm, and that of 10 AWG wire is about 6mm, which facilitates the installation of the wire in different laying environments, such as threading smoothly in narrow pipes.

In terms of temperature performance, the long-term allowable operating temperature of Thw-Ls aluminum building wire is 90℃, and the maximum temperature during a short circuit (with a maximum duration of no more than 5 seconds) does not exceed 250℃. This parameter ensures that the wire can maintain stable performance under normal working conditions and special situations such as short circuits, and will not affect its service life and safety due to excessive temperature.

Thw-Ls aluminum building wire, with its unique performance advantages, has a wide range of distinctive uses in various building scenarios and can meet the electricity demand in different environments.

In residential buildings, 10 AWG wires are often used in lighting systems and ordinary socket circuits. The lighting fixtures in living rooms, bedrooms, studies and other areas of residential buildings, such as chandeliers, ceiling lamps, downlights, etc., generally have low power, and the total power is usually within a few hundred watts. The current-carrying capacity of 10 AWG wires can fully meet their power supply needs. At the same time, the household appliances connected to ordinary sockets, such as TVs, refrigerators, washing machines, etc., have relatively moderate power. 10 AWG wires can stably supply power to these household appliances, and their low smoke zero halogen characteristics can reduce the release of smoke and toxic gases in case of fire, striving for more escape time for residents and greatly improving the safety of household electricity use.

4 AWG wires play an important role in the main incoming lines of residences and power supply circuits for high-power equipment. The main incoming line of a residence needs to carry the electricity load of the entire family. Especially when multiple high-power electrical appliances work at the same time, the current will increase significantly. The high current-carrying capacity of 4 AWG wires can ensure the stable input of electricity. For high-power electrical appliances such as central air conditioners and electric heating equipment in residences, 4 AWG wires can also provide reliable power support to ensure the normal operation of these equipment.

In commercial buildings, such as shopping malls and office buildings, there are dense personnel and numerous equipment, so higher requirements are put forward for the safety and stability of wires. 10 AWG wires can be used in lighting systems in shopping malls and socket circuits of small shops to ensure normal lighting in shopping malls and electricity use of small electrical appliances in shops. 4 AWG wires are suitable for power supply of high-power equipment such as central air conditioning hosts and large elevators in office buildings, as well as the main power distribution circuits of shopping malls, ensuring the stable operation of these large equipment and reducing the interruption of commercial activities caused by wire faults.

In places with high safety requirements such as hospitals and schools, the flame retardant and low smoke zero halogen properties of Thw-Ls aluminum Building wires are fully reflected. 10 AWG wires can be used in lighting and medical equipment socket circuits in wards, operating rooms and other areas of hospitals. Their low smoke zero halogen properties can avoid the release of toxic gases that harm patients and medical staff in case of fire. In school teaching buildings, laboratories and other places, 4 AWG wires can be used for main incoming lines and power supply of large teaching equipment. The flame retardant performance can delay the spread of fire and strive for time for the evacuation and rescue of teachers and students.

In addition, the wire is also applicable to some special building scenarios, such as subway stations, airport terminals and other public places with dense personnel and large passenger flow. In these places, the safety performance of wires is crucial. The characteristics of Thw-Ls aluminum building wires can meet their strict safety standards and provide reliable guarantee for power supply in public places.

In terms of material selection and style design, Thw-Ls aluminum building wire fully combines performance, safety and practicability, enabling it to adapt to the needs of various building environments.

In terms of materials, the conductor is made of high-purity aluminum. High-purity aluminum has good conductivity, which can effectively reduce losses during current transmission and ensure efficient transmission of electricity. Compared with copper, aluminum has a smaller density and lighter weight, which makes the wire more convenient in transportation and installation, reducing construction difficulty and labor costs. At the same time, aluminum has relatively abundant resources and low price. Using aluminum as a conductor can reduce the production cost of the wire on the premise of ensuring performance, providing users with more cost-effective products.

The insulation layer is made of low smoke zero halogen polyvinyl chloride (LSZH PVC) material. This material has excellent insulation performance, which can effectively block current, prevent electric leakage accidents and ensure electricity safety. Compared with traditional PVC materials, LSZH PVC releases very little smoke when burned and does not contain toxic gases such as halogens. This characteristic is particularly important in case of fire. It can reduce the obstruction of smoke to people's sight, reduce the harm of toxic gases to the human body, and also reduce the corrosion to equipment, creating favorable conditions for personnel evacuation and fire rescue.

In terms of style, Thw-Ls aluminum building wire is usually of a single-core structure, with an LSZH PVC Insulation layer wrapped around the outer layer. The single-core structure makes the wire more flexible in the laying process, facilitating threading and installation in narrow spaces. The insulation layer has various colors, commonly yellow, green, black, etc. Wires of different colors are convenient for construction personnel to identify and distinguish different circuits during wiring, such as phase lines, neutral lines, ground lines, etc., reducing the occurrence of construction errors.

The surface of the wire is smooth and flat, which not only helps reduce friction resistance during pipe laying, but also prevents scratches by sharp objects during transportation and installation, protecting the integrity of the insulation layer. In addition, some models of wires will add a wear-resistant protective layer outside the insulation layer to further enhance the durability of the wire, enabling it to adapt to more harsh laying environments.

The production process of Thw-Ls aluminum building wire is rigorous and complex, and each link is subject to strict quality control to ensure that the performance and quality of the product meet relevant standards and requirements.

The first step is the preparation of the Aluminum Conductor. High-purity aluminum ingots are selected as raw materials, and aluminum rods are obtained through smelting, ingot casting and other processes. The aluminum rod is drawn on a wire drawing machine, and through dies of different specifications, the aluminum rod is drawn into Aluminum Wires of the required wire diameter. During the wire drawing process, the drawing speed and temperature need to be accurately controlled to ensure the dimensional accuracy and mechanical properties of the Aluminum Wire. The drawn aluminum wire also needs to undergo annealing treatment, which can eliminate the internal stress generated during the drawing process of the aluminum wire, improve the Flexibility and conductivity of the aluminum wire, and make it more suitable for subsequent processing and use.

Next is the extrusion molding of the insulation layer. LSZH PVC granular raw materials are added to the extruder and heated and melted to form a molten PVC melt. Then, the prepared aluminum conductor is passed through the die head of the extruder, and at the same time, the PVC melt is evenly extruded and wrapped around the outer layer of the aluminum conductor to form the insulation layer. During the extrusion process, the extrusion temperature, extrusion speed and die size need to be strictly controlled to ensure that the insulation layer has uniform thickness, smooth surface, and is closely combined with the conductor without defects such as bubbles and impurities. The thickness of the insulation layer is accurately adjusted according to the wire diameter of the wire to ensure that its insulation performance meets the requirements.

The wire after extrusion molding needs to be cooled, usually by water cooling. The cooling process can make the insulation layer solidify and shape quickly, ensuring the dimensional stability and performance stability of the wire. The cooled wire is tested by a spark tester, and through high-voltage electrical testing, it is checked whether the insulation layer has defects such as pinholes and damage to ensure that the insulation performance meets the standard. If unqualified wires are found, they will be marked and repaired or scrapped.

Subsequently, the wire enters the traction and take-up process. The traction machine pulls the wire at a constant speed to ensure uniform tension of the wire, avoiding the wire being stretched or damaged due to excessive tension. The take-up machine neatly winds the wire on the reel for transportation and storage. During the take-up process, the take-up speed and tension must be controlled to ensure that the wire is arranged tightly and neatly on the reel without looseness or entanglement.

During the production process, sampling tests on various properties of the wire are also required, such as the DC resistance of the conductor, the thickness of the insulation layer, voltage resistance performance, flame retardant performance, low smoke zero halogen performance, etc. These tests can timely find problems in the production process and take corresponding measures for rectification to ensure the stability of product quality. At the same time, the environment of the production workshop also needs to be strictly controlled to keep the workshop clean and hygienic, avoiding the impact of dust, impurities, etc. on product quality.

The packaging design of Thw-Ls aluminum building wire fully considers the needs of product protection, transportation and storage, ensuring that the wire remains in good condition before reaching the user.

For short-length wires, plastic reels are usually used for packaging. Plastic reels are light in weight, low in cost, and have certain strength, which can protect the wires from damage during transportation and handling. When the wire is wound on the plastic reel, it is arranged neatly and tightly to avoid mutual extrusion and wear. A layer of plastic film is 套在 the outside of the reel, which can play a role in moisture-proof and dust-proof, preventing the insulation layer of the wire from being polluted and damaged.

For long-length wires, wooden or iron cable reels are used for packaging. Wooden cable reels have certain buffer performance, which can reduce the impact of vibration during transportation on the wires, and the cost is relatively low. Iron cable reels have higher strength and bearing capacity, suitable for long-distance transportation and multiple turnovers, and can better protect the wires. Whether it is a wooden or iron cable reel, the wire must be wound neatly and orderly, and the outside of the cable reel is wrapped with plastic film or linen to further enhance the protection effect.

In terms of packaging marking, each package will clearly mark the product name, model specification, length, rated voltage, production date, manufacturer and other information. This information is convenient for users to check when receiving and accepting products, ensuring that the received products meet the order requirements. At the same time, warning signs such as "Do not press heavily" and "Moisture-proof" are printed on the package to remind transport and handling personnel to pay attention to correct operation methods to avoid damage to the product.

In addition, the selection of packaging materials also takes into account environmental protection requirements. Packaging materials such as plastic films are 尽量选用 recyclable or degradable materials to reduce environmental pollution. Wooden cable reels have undergone strict treatment, meeting the quarantine standards for international transportation, avoiding carrying pests.

The transportation process of Thw-Ls aluminum building wire needs to strictly abide by relevant regulations and operating procedures to ensure that the product is not damaged during transportation and arrives at the destination safely.

In terms of transportation mode selection, according to the transportation distance, quantity and customer requirements, road transportation, railway transportation or water transportation can be chosen. Road transportation has the characteristics of high flexibility and fast transportation speed, suitable for short-distance transportation and small-batch cargo transportation, and can directly deliver the wires to the construction site or designated place. Railway transportation is suitable for long-distance transportation and large quantities of goods, with relatively low transportation costs, less affected by weather, and a relatively stable transportation process. Water transportation is suitable for long-distance transportation of bulk goods, especially for export products, water transportation is an economical choice.

Before transportation, the packaged wires need to be fixed. For short-length wires packaged with plastic reels, they should be neatly stacked in the carriage of the transport vehicle and fixed with ropes or partitions to prevent shaking and collision during transportation. For long-length wires packaged with cable reels, steel wire ropes or chains should be used to firmly fix the cable reels on the transport vehicle to ensure that they will not roll or topple during transportation.

During transportation, the wires should be avoided from direct sunlight, rain and snow. Direct sunlight will cause the wire temperature to rise, which may affect its insulation performance; rain and snow will make the wire damp, affecting its service life. Therefore, during transportation, the wires should be covered, such as using tarpaulins, to protect the wires from harsh weather.

At the same time, transport vehicles must abide by traffic rules during driving, maintain stable driving, avoid sudden braking, sharp turns and other operations, and reduce the impact and vibration on the wires. For wires transported over long distances, the fixing situation and packaging integrity should be checked regularly, and problems should be handled in a timely manner to ensure the safety of the wires.
