Problems solved by technology

[0002] The braided layer on the traditional insulated cable is often made of armored layer, and the main material of the armored layer is stainless steel or steel wire. As the stainless steel or steel wire material is used for a long time, it will often be damaged. As a result, the quality and life of the entire cable will be greatly reduced. Therefore, in view of the above problems, it is necessary to design a 3000V rated voltage 3000V shielded braided silicone rubber insulated cable.

Abstract

The invention discloses a shielding braid layer silicone rubber insulated cable with rated voltage of 3000V, which belongs to the technical field of cables. The cable comprises a conductor, an isolating layer, an insulating layer, a braid layer and a sheath, wherein the isolating layer is wrapped on the surface of the conductor, the insulating layer is sleeved outside the whole formed by the isolating layer and the conductor, the braid layer is arranged outside the insulating layer, and the sheath is sleeved outside the braid layer. The coating layer composed of the resin, the cross-linking agent, the elastomer, the antioxidant, the flame retardant, the mildew preventive and the moisture-proof agent is coated on the glass fiber to form the braid layer, and then the insulating layer, the sheath and the isolating layer are utilized to form the cable. In comparison with the armored layer, the cable has the characteristics of easy bending, pressure resistance, moisture resistance, fire resistance, aging resistance, low temperature resistance, high temperature resistance and the like.
