Double-layer insulation colour separation copper core BV wire

The utility model relates to a double-layer insulation colour separation copper core BV wire. The lateral side of the copper core is covered by a double-layer colour separation insulation layer. A middle insulation layer, which is between the copper core and the lateral insulation layer, is a fire-retardant insulation layer. The utility model overcomes the disadvantages of the ordinary BV wire made by the prior art, which are poor insulation property and fire retardance and unreliable security. Through the design mentioned above, the utility model greatly promotes insulation property of a BV wire and plays the function of fire retardance; The utility model has the advantages of simple structure, clear layer of the insulation layers and safe and reliable process of use.
