(II) Characteristic Uses
Ar2V Yjlv single-core 1X185mm, 1X300mm² flame-retardant XLPE insulated aluminium cable has distinctive uses in multiple fields due to its unique performance advantages.
In the industrial field, this cable plays an important role. The high-voltage power distribution system of the factory needs stable and reliable power transmission. The 1X185mm² and 1X300mm² cables can respectively provide power support for large motors, transformers and other equipment with different powers. For example, in large manufacturing factories, it is used to connect high-voltage distribution cabinets and large production equipment to ensure the normal operation of the equipment. Due to its flame-retardant performance, it can reduce the risk of fire in the industrial environment and ensure production safety.
In urban power grid construction, this cable is an ideal choice for connecting lines between substations and overhead transmission lines. The urban distribution network has a large load and a long transmission distance. The 1X300mm² cable with a large current-carrying capacity can meet the transmission needs of a large amount of electricity, while the 1X185mm² cable can be used for some branch lines. Its light weight reduces the bearing pressure during overhead laying, reduces the load on towers and other infrastructure, and also reduces the difficulty of installation and construction.
High-rise buildings and large public facilities have extremely high requirements for the safety of power supply, and this cable can play a key role as an
Emergency Power Supply line. In case of fire and other emergencies, its flame-retardant performance can delay the spread of fire, buy time for personnel evacuation and equipment rescue, and at the same time, it can maintain the power supply of key equipment such as fire pumps and emergency lighting for a certain period of time, ensuring personnel safety and the basic operation of facilities.
In the new energy field, such as the power output lines of large wind farms and photovoltaic
Power Stations, this cable is also used. Wind farms and photovoltaic power stations are usually located outdoors with harsh environments. The weather-resistant sheath of the cable can resist the erosion of natural factors such as wind, sun and rain, and its good electrical performance can efficiently transmit the generated electricity to the power grid.
In addition, in power transmission in some remote areas, this cable is also widely used because of its light weight, convenient transportation and laying, which can effectively reduce the cost and difficulty of power transmission and provide guarantee for power supply in remote areas.
(III) Material and Style
Material
The conductor is made of high-purity aluminium material with a purity of ≥99.5%. High-purity aluminium has good conductivity and can meet the needs of high-voltage power transmission. At the same time, aluminium has a low density, making the cable light in weight, which is about 40% lighter than
Copper Cables of the same specification, which is beneficial to transportation and laying. Aluminium also has certain ductility and toughness, which is convenient for processing into a single-core structure.
The insulation layer is made of flame-retardant XLPE (cross-linked polyethylene) material. After special cross-linking treatment, this material has excellent electrical performance, mechanical performance and heat resistance. Its flame-retardant property is achieved through special treatment, which can inhibit the spread of flame and reduce smoke release in case of fire. XLPE material has good chemical stability, is not easy to age, and can maintain good insulation effect for a long time.
The shielding layer is made of semi-conductive material, whose resistivity is between that of conductor and insulator. It can be closely combined with the insulation layer, evenly distribute the electric field, avoid the insulation layer being broken down due to excessive local electric field strength, and improve the operation safety of the cable.
The sheath layer is made of weather-resistant PVC (polyvinyl chloride) or PE (polyethylene) material. PVC material has good mechanical strength, wear resistance and chemical corrosion resistance, and the price is relatively low; PE material has better low-temperature resistance, impact resistance and
Flexibility, and is more suitable for scenarios with higher requirements for sheath performance. Both materials have certain ultraviolet resistance and can adapt to the outdoor environment.
Style
The cable has a single-core structure, which is cylindrical as a whole with a compact structure. The single-core design reduces mutual interference between core wires and is beneficial to high-voltage power transmission.
The color of the cable usually depends on the sheath material.
PVC Sheath is generally black, and PE sheath can be black or other colors. Black can better absorb heat, reduce the impact of ultraviolet rays on the cable, and is also convenient for identification in the outdoor environment.
In terms of appearance, the surface of the cable is smooth and flat, with no obvious bulges, depressions or cracks. The sheath layer is printed with clear marks, including cable model, specification, rated voltage, manufacturer, production date, certification mark and other information, which is convenient for users to identify and trace the product.
When the cable is packaged in coils, the coil diameter is large, which usually varies according to different cross-sectional specifications. The coil diameter of 1X185mm² cable is about 1.2 meters, and that of 1X300mm² is about 1.5 meters. Such a coil diameter is not only convenient for storage and transportation, but also easy to unfold during laying.
(IV) Production Process
The production process of Ar2V Yjlv single-core 1X185mm, 1X300mm² flame-retardant XLPE insulated aluminium cable is complex and rigorous. Every link from raw material processing to finished product inspection is strictly controlled to ensure product quality.
Conductor manufacturing is the first step of production. First, high-purity aluminium ingots are smelted to remove impurities, and the purity of aluminium is increased to ≥99.5%. The smelted aluminium liquid is made into aluminium rods through continuous casting and rolling process, and the diameter of the aluminium rods is determined according to the final conductor cross-sectional specification. Then, the aluminium rod is drawn into
Aluminium Wires of the required diameter through a wire drawing machine. During the wire drawing process, it is necessary to control the wire drawing speed and die precision to ensure that the diameter of the aluminium wire is uniform, the surface is smooth, and there are no scratches or burrs. After that, the aluminium wires are stranded or compacted according to a certain process to make a single-core conductor. The compaction process can improve the filling coefficient of the conductor and reduce the outer diameter of the conductor.
Insulation layer extrusion is one of the key processes. The single-core conductor is fed into the extruder, and at the same time, the flame-retardant XLPE material is heated to a molten state. The molten XLPE material is evenly wrapped around the outside of the conductor through an extrusion die to form an insulation layer. During the extrusion process, it is necessary to strictly control the extrusion temperature, extrusion speed and die pressure to ensure that the thickness of the insulation layer is uniform, closely combined with the conductor, and free of bubbles, material shortages and other defects. The extruded
Insulated Core needs to undergo cross-linking treatment, usually by means of warm water cross-linking or steam cross-linking, so that the XLPE molecules form a three-dimensional network structure, thereby improving its mechanical properties, heat resistance and electrical properties. The cross-linked insulated core should be cooled to set.
The application of the shielding layer is carried out after the insulation layer is processed. The shielding layer is made of semi-conductive material, which is applied to the surface of the insulation layer by extrusion or lapping. The extrusion method is to heat and melt the semi-conductive material and extrude it to the surface of the insulation layer through a die, which is closely combined with the insulation layer; the lapping method is to lap the semi-conductive tape on the surface of the insulation layer with a certain overlap rate. The thickness of the shielding layer should be uniform to ensure that it can effectively and evenly distribute the electric field.
Sheath layer extrusion is the last major process. The core with shielding layer is fed into the sheath extruder. PVC or PE material is heated and melted in the extruder, and then evenly wrapped around the outside of the shielding layer through an extrusion die to form the sheath layer. During the extrusion process, various parameters should be controlled to ensure that the thickness of the sheath layer is uniform, the surface is smooth, closely combined with the internal structure, and free of bubbles, cracks and other defects. The extruded cable is cooled, pulled, and taken up to form coiled finished cables.
During the production process, multiple quality inspections are required. After the conductor is manufactured, its diameter, DC resistance, tensile strength and other indicators are tested; after the insulation layer is extruded and cross-linked, the thickness, insulation resistance, voltage resistance performance, flame retardancy and other properties of the insulation layer are tested; after the shielding layer is applied, its resistance, bonding force with the insulation layer and other properties are tested; after the sheath layer is extruded, the thickness, tensile strength, elongation at break, weather resistance and other properties of the sheath are tested. The finished cable also needs to undergo overall electrical performance tests, mechanical performance tests and environmental performance tests to ensure that all indicators meet relevant standards and design requirements.
The production environment also has an important impact on product quality. The workshop should be kept clean and dry, and the temperature and humidity should be controlled within appropriate ranges to avoid dust, impurities and other factors affecting product performance. Production equipment is regularly maintained and calibrated to ensure its operating accuracy and stability, and improve production efficiency and the consistency of product quality.
