Super-flexible fireproof power cable adopting ceramic silicone rubber insulation and stainless steel interlocking sheath

Abstract

The invention relates to a super-flexible fireproof power cable adopting ceramic silicone rubber insulation and a stainless steel interlocking sheath, which effectively solves the problems that the insulating layer of a conventional cable is easy to absorb water to get damp, the bending radius of the cable is large. The cable adopts the solution that the cable comprises a cable conductor, wherein a lapping inner layer is arranged in the outer layer of the cable conductor; a ceramic silicone rubber insulating layer is extruded on the cable conductor; an oxygen separation strap is lapped on the ceramic silicone rubber insulating layer; the exterior of the lapping inner liner layer is wrapped with an interlocking armor layer made of stainless steel straps. The cable adopts a novel and unique structure, fundamentally solves the problem that the insulating layer of the cable absorbs water and gets damp, enhances the flame retardance function, greatly reduces the bending radius, improves the flexibility, and improves the fire emergency guarantee level.

Description

technical field [0001] The invention relates to the technical field of wire and cable manufacturing, in particular to a super-flexible fireproof power cable with ceramic silicon rubber insulation, stainless steel interlocking armor. Background technique [0002] The flexible fireproof cables currently promoted in the market are insulated with multi-layer mica tape, and the sheath technology of argon arc welding of copper tape is covered with embossing, which requires strict drying and moisture-proof treatment during production, laying and jointing of cables; Production and laying require that the bending radius is not less than 40 times the diameter of the cable, etc., but a slight negligence in the production, laying, and joint links can easily cause the cable insulation to absorb water and get damp. Once the fire is sent after laying, the fire protection cannot be started due to grounding short circuit. Equipment, resulting in undue losses to users, the protection rate is ...

AI Technical Summary

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a ceramic silicon rubber insulation, stainless steel interlocking armor, ultra-flexible fireproof power cable, which effectively solves the problem that the existing cable insulation layer is easy to absorb water and get wet. Problems such as large cable bending radius

[0005] The invention has a novel and unique structure, which fundamentally solves the problem of water absorption and dampness of the cable insulation layer, improves the flame retardant and fire prevention function, greatly reduces the bending radius of the cable, increases its flexibility, and improves the protection level of the cable fire emergency
