What material is the mechanical power cord made of?

The materials of mechanical power cords mainly include bare copper wire, PVC, rubber, etc. Specifically, the core material of mechanical power cords is mostly bare copper wire, which has good conductivity and corrosion resistance, and can ensure the stability and safety of current transmission. The sheath material can be PVC or rubber, both of which have excellent insulation performance and durability, and can protect the internal core from the influence of the external environment, while increasing the service life of the power cord. In addition, the specifications and certifications of mechanical power cords are also one of its important characteristics. For example, some mechanical power cords may pass CCC or VDE certifications, which indicate that the safety and quality of the product have reached specific standards. In the classification of power cords, in addition to mechanical power cords, there are also various standard power cords, such as American standard power cords, which include NISPT-2 double-layer insulated flat wire, SPT-1W single-layer insulated grooved flat wire, SJTW waterproof power cord, SJTO oil-proof power cord, etc. These power cords are designed and manufactured according to different usage environments and needs3. At the same time, the specifications of the wiring harness also depend on the number of wires and cables, cross-sectional area, insulation materials and other factors. According to the insulation material classification, there are silicone wires, low-smoke halogen-free electronic wires (XLPE electronic wires), PVC wires, Teflon wires, etc. These classifications reflect the differences in electrical performance, heat resistance and service life of wires.
