Rubber insulated wires are widely used in electrical equipment and lighting equipment. The rated AC voltage is 500 volts. The long-term working temperature of the conductive core is 65 degrees. Most of them are fixedly laid. Copper conductive wire core rubber flexible wire), the cross-sectional range is 0.75-630 square millimeters, the conductive wire core is 1-4 cores, the basic structure of the wire is a conductor, rubber insulation, cotton yarn or glass fiber woven and waxed. There are also BXF and BLXF type copper-aluminum conductive core neoprene wires, which have a relatively simple structure and are only covered with a layer of neoprene rubber on the outside of the conductor, which improves sunlight resistance, flame resistance, and salt resistance, and can save cotton yarn and natural glue.
