General rubber plastic power cord structure
1. Conducting power core: For power, lighting, and electrical equipment internal installation, copper core is preferred. For large-section conductors, tight-core cores should be used; conductors for fixed installation generally use type 1 or type 2 conductors. structure.
2. Insulation: Insulating materials are generally made of natural styrene-butadiene rubber, polyvinyl chloride, polyethylene, butyronitrile-polyvinyl chloride, etc .; heat-resistant power cords are made of polyvinyl chloride with a temperature resistance of 90 ° C.
3. Sheath: There are five kinds of sheath materials: polyvinyl chloride, cold-resistant polyvinyl chloride, ant-proof polyvinyl chloride, black polyethylene, and neoprene.
Special cold-resistant and outdoor overhead laying should choose black polyethylene and neoprene-sheathed power cords.
Under external force, corrosion, humidity, and other environments, rubber or plastic-sheathed power cords can be used.
1. Because the product is often moved, bent, twisted, etc., it is required that the power cord be flexible, stable in structure, not easy to kink, and have certain abrasion resistance; the plastic-sheathed rubber power cord can be buried directly in the soil.
3. The grounding wire adopts a yellow-gr...
