Fire-retardant, heat-resistant and explosion-proof cable

Abstract

The invention discloses a fire-retardant, heat-resistant and explosion-proof cable. The fire-retardant, heat-resistant and explosion-proof cable comprises a cable core. The fire-retardant, heat-resistant and explosion-proof cable is characterized in that the cable core is formed through stranding at least one set of conductor; the peripheries of the conductor are wrapped with insulating layers; the cable core is wrapped with a wrapping tape layer; the periphery of the wrapping tape layer is wrapped with a shielding layer; the periphery of the shielding layer is wrapped with a tensile compressive layer; the periphery of the tensile compressive layer is wrapped with a heat-resistant and flame-retardant glass fiber tape; the periphery of the heat-resistant and flame-retardant glass fiber tape is wrapped with a protective layer; and a flame-retardant sealant is filled between the cable core and the wrapping tape layer. The fire-retardant, heat-resistant and explosion-proof cable of the invention is advantageous in simple structure, excellent mechanical performance, low cost, safe operation, convenient use, improved performance, low capacitance, low inductance, improved explosion-proof and safety performance as well as more convenient and reliable use. Influence on explosion-proof and safety performance of the cable, which is caused by an accident in construction and installation, can be avoided.

Description

technical field [0001] The invention relates to the field of explosion-proof cables, in particular to a flame-retardant, heat-resistant and explosion-proof cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires, and each group is twisted with at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulated overlay. With the rapid development of the economy, there are various special requirements for cables, but the current cable waterproof, anti-static field, explosion-proof performance, and pressure resistance performance are poor, especially the cable can not have any problems during use, the single cable structure It has been unable to meet the diverse requirements. [0003] Therefore, there is an urgent need for an improved technology to solve this problem in the prior art. Contents of the invention ...
