Wires and cables

Basic StructureConductor: It is the part of the wire and cable that is responsible for conducting current, usually made of copper or aluminum materials. Copper conductors have excellent conductivity and good oxidation resistance, but are more expensive; aluminum conductors are lightweight and cost-effective but have relatively lower conductivity and are prone to oxidation. The forms of conductors include single core, multi-core, and multi-stranded. Multi-stranded conductors are more flexible, suitable for mobile scenarios.Insulation Layer: Its main function is to prevent short circuits between conductors and ensure the safe operation of cables. Common insulation materials include PVC (polyvinyl chloride), XLPE (cross-linked polyethylene), and PE (polyethylene). XLPE insulation has excellent heat resistance and insulation properties, while PVC insulation is low-cost and flexible but has poor temperature resistance.Shielding Layer (optional): Generally made of materials such as copper mesh or aluminum foil, used to prevent external electromagnetic interference. Commonly found in control cables and communication cables, it ensures the stability and accuracy of signal transmission.Jacket Layer: Usually made of materials like PVC, rubber, or PE, it primarily provides external protection, making the cable abrasion-resistant, corrosion-resistant, and waterproof, thus protecting the internal structure of the cable from external environmental influences.Armored Layer (optional): Made of steel tape, steel wire, etc., primarily used to enhance the mechanical strength of the cable, increasing its resistance to external damages, suitable for underground or complex construction environments, such as direct burial underground, crossing rivers, etc.
