Problems solved by technology

[0002] In recent years, with the continuous development of social economy, the need for urban power transmission and distribution lines to be equipped with utility poles, the application of cables has become a significant development trend, and the number of cables and cable kilometers on the line are also increasing day by day. Due to urban development According to planning requirements, more and more cable tunnels are used. In order to save channel resources, the application of small-diameter tunnels, pipes + cable wells for laying cables is very common. While bringing convenience to people, there are also many problems. Among them, due to the influence of human factors, construction, and environmental factors, when a fire, breakdown or even explosion accident occurs, an accident will occur in the cable, and the heat and energy generated by the cable are enough to threaten the surrounding cable lines, facilities, and people. , resulting in a more serious secondary accident

Abstract

The invention discloses a cable fireproof and explosion-proof blanket, and relates to the technical field of cable protection. The cable fireproof and explosion-proof blanket comprises a Kevlar fiberlayer, a flexible fireproof and explosion-proof inner layer and a plain weave fabric surface layer coated on the flexible fireproof and explosion-proof inner layer, wherein the plain weave fabric surface layer is formed by hot pressing a plurality of layers of ultrahigh molecular weight polyethylene fiber base cloth infiltrated with vinyl ester resin particles, the vinyl ester resin particles arediscretely arranged on the ultrahigh molecular weight polyethylene fiber base cloth at intervals of 1-2 mm, the flexible fireproof and explosion-proof inner layer comprises a flexible fireproof layer,a flexible heat insulation layer, an explosion-proof core layer, an arc-proof metal layer and an epoxy organic glass fiber reinforced plastic layer which are sequentially arranged in a matched mannerthrough mutually matched meshing parts, and a connecting structure is arranged outside the plain weave fabric surface layer. According to the fireproof and explosion-proof blanket for the cable, thecable is good in fireproof performance, flame retardance and explosion-proof performance.
