(III) Material and Style
Conductor Material
The core part of the cable uses pure copper (Copper) conductors. Pure copper, as a conductor material, has many significant advantages. Firstly, pure copper has excellent electrical conductivity, which means that current can flow smoothly during power transmission, greatly reducing resistance loss and thus improving the efficiency of power transmission. Secondly, pure copper has good thermal conductivity. When the cable generates a certain amount of heat during operation, it can dissipate quickly, avoiding the impact on the performance and service life of the cable due to heat accumulation.
Moreover, pure
Copper Conductors have good mechanical strength and can withstand a certain amount of tension and pressure, so they are not easy to break or be damaged during the laying and use of the cable. At the same time, pure copper has good corrosion resistance and can resist the erosion of some corrosive substances in the external environment, further extending the service life of the cable.
Insulation Layer Material
The insulation layer is made of cross - linked polyethylene (XLPE) material, which is an excellent insulating material. It has excellent high and low temperature resistance and can work stably for a long time in an environment of - 40℃ to 90℃. Its insulation performance will not be affected in cold winters, hot summers, or some industrial environments with temperature fluctuations.
XLPE material also has the characteristic of chemical corrosion resistance, which can resist the erosion of a variety of chemical substances, ensuring that the insulation layer will not be damaged in some environments with chemical pollution, thus ensuring the safety of power transmission. In addition, its insulation performance is stable, with a small dielectric constant and large insulation resistance, which can effectively prevent current leakage, reduce power loss, and ensure the efficiency and safety of power transmission. At the same time, XLPE material has strong anti - aging properties and will not easily crack or harden after long - term use, extending the insulation life of the cable.
Sheath Layer Material
The sheath layer is made of polyvinyl chloride (PVC) material. PVC material has good wear resistance. During the laying, handling and use of the cable, it can resist external friction and collision, reducing damage to the sheath layer. It also has excellent weather resistance and can withstand the impact of natural environments such as sunlight and wind and rain erosion, maintaining good performance when used outdoors.
Furthermore, PVC material has flame - retardant performance. When exposed to an open flame, it can inhibit the spread of the flame, reduce the risk of fire accidents, and provide additional safety guarantees for power transmission. The sheath layer can provide reliable protection for the internal structure of the cable, resisting external mechanical damage, moisture and chemical erosion, and ensuring that the cable can work normally in various complex environments.
Style Design
The cable adopts a multi - core structure (
4 Cores), which meets common power transmission needs. The 4 - core structure can meet the power requirements of the three - phase four - wire system. In the power system, three - phase electricity can provide stable power, and the neutral wire is used to balance the three - phase current to ensure the normal operation of electrical equipment.
The overall appearance design is simple and elegant. The sheath layer has a uniform color and a smooth surface, which is easy to identify and lay. Cables of different specifications are distinguished by the difference in cross - sectional area in appearance, making it convenient for users to choose according to actual needs.
(IV) Production Process
Conductor Manufacturing
The manufacturing of pure
Copper Conductors goes through a strict process. Firstly, high - quality pure copper raw materials are selected to ensure that the purity and performance of the raw materials meet the requirements. Then, the copper material is drawn into
Copper Wires of the required diameter through a wire drawing process. During the wire drawing process, the drawing speed and tension need to be precisely controlled to ensure the dimensional accuracy and mechanical properties of the copper wires.
After that, multiple copper wires are stranded to form a conductor. The stranding process can improve the
Flexibility and bending performance of the conductor, making it easy to lay the cable. During the stranding process, it is necessary to ensure that the copper wires are arranged evenly and tightly to avoid looseness and broken wires. After stranding, the conductor is annealed. Through heating and cooling processes, the internal stress of the conductor is eliminated, and the electrical and mechanical properties of the conductor are improved.
Insulation Layer Extrusion
When extruding the XLPE insulation layer on the outer layer of the conductor, advanced extrusion equipment and processes are adopted. Firstly, the XLPE material is pretreated to remove impurities and moisture, ensuring the purity of the material. Then, the treated material is added to the extruder and melted and plasticized under high temperature and pressure.
The melted XLPE material is evenly coated on the surface of the conductor through a mold to form an insulation layer. During the extrusion process, the extrusion temperature, speed and pressure need to be precisely controlled to ensure that the insulation layer has a uniform thickness, a smooth surface and is closely combined with the conductor. After extrusion, the insulation layer is cross - linked. Through heating and other methods, the XLPE molecules form a cross - linked structure, thereby improving the performance of the insulation layer.
Sheath Layer Extrusion
The extrusion process of the sheath layer is similar to that of the insulation layer, but the process parameters need to be adjusted according to the characteristics of the PVC material. Firstly, the PVC material is mixed evenly with relevant additives (such as plasticizers, stabilizers, flame retardants, etc.) in a certain proportion to ensure that the material has good processing performance and performance indicators.
Then, the mixed material is added to the extruder, melted and plasticized, and then coated on the outer layer of the insulation layer through a mold to form a sheath layer. During the extrusion process, parameters such as extrusion temperature and speed should be controlled to ensure that the sheath layer has a uniform thickness, a flat surface and is closely combined with the insulation layer. After extrusion, the sheath layer is cooled to make it shape quickly.
Finished Product Inspection
The cables after production need to undergo strict finished product inspection. The inspection items include appearance inspection, dimension measurement, electrical performance testing, mechanical performance testing, etc. The appearance inspection mainly checks whether the sheath layer of the cable has defects such as damage, bubbles and depressions; the dimension measurement checks whether the conductor cross - sectional area, insulation layer thickness and sheath layer thickness meet the specification requirements; the electrical performance testing includes insulation resistance testing and voltage resistance testing to ensure that the insulation and conductive performance of the cable meet the standards; the mechanical performance testing includes tensile strength and elongation at break to inspect whether the mechanical strength of the cable meets the standards. Only cables that pass all inspection items can be judged as qualified products.
II. General Product Information
(I) Packaging
Packaging Materials
In order to ensure that the cable is not damaged during transportation and storage, appropriate packaging materials are used. For small - size cables, cardboard boxes are usually used for packaging. Cardboard boxes have a certain degree of strength and rigidity and can resist a certain amount of external impact. Moisture - proof paper is placed inside the box to prevent the cable from getting damp.
For large - size and long - length cables, cable reels are used for packaging. There are two types of cable reels: wooden and steel. Wooden cable reels are lighter in weight and lower in cost, suitable for short - distance transportation; steel cable reels have higher strength and stronger bearing capacity, suitable for long - distance transportation and multiple uses. The size of the cable reel is designed according to the specification and length of the cable to ensure that the cable can be neatly wound on the cable reel.
Packaging Methods
In the packaging process, the cable is first neatly wound on the cable reel or put into a cardboard box to avoid twisting and knotting of the cable. For cables packaged with cable reels, protective devices are installed at both ends of the cable to prevent damage to the cable ends. Then, the entire cable is wrapped with stretch film to play a role in moisture proofing and dust proofing.
In the cardboard box packaging, buffer materials such as foam and bubble film are filled inside the box to reduce the shaking and collision of the cable during transportation. After packaging, the product information such as product name, specification, length, quantity, production date and batch number is marked on the outside of the package to facilitate user identification and acceptance. At the same time, warning signs such as "Do Not Invert" and "Handle with Care" are also marked to remind transportation and handling personnel to pay attention.
