Embodiment Construction

[0005] The figure includes a silicone rubber insulated fire-resistant flexible cable, including a cable inner core and a cable outer layer wrapped outside the cable inner core. The inside of the cable inner core is a conductive core 1, an insulating layer 2 and a fire-resistant layer 3 in sequence from the inside to the outside. Inside the outer layer of the cable is a flame retardant tape 4 and a sheath layer 5 in sequence from the inside to the outside, and a flame retardant filler 6 is provided in the gap between the outer layer of the cable and the inner core of the cable. Flame-retardant fillers 7 are arranged in the gaps between the inner cores of the cables.

[0006] The conductor monofilament of the conductive core is a round copper monofilament. The round copper monofilament is a bare round annealed copper wire or a round copper monofilament whose surface is coated with tin, and the copper wire is made of high-purity oxygen-free copper. The number of cable inner core...

Abstract

The invention aims to provide a silicone rubber insulating fire-resisting flexible cable and can effectively solve the problems that a control cable in the prior art has a high halogen content, is inflammable, generates toxic gas after combustion, and the like. The invention relates to a silicone rubber insulating cladding high temperature resisting flexible cable which comprises an inner core and a cable outer layer clad outside the inner core, wherein the inside of the inner core comprises a conductor wire core, an insulating layer and a fire-resisting layer from inside to outside in sequence; the inside of the cable outer layer comprises a fire-retardant tape and a cladding layer from inside to outside in sequence; and a flame-retardant filler is arranged in a gap between the cable outer layer and the inner core. The invention can realize fire resistance of the cable mainly by cladding mica on the surface of a silicone rubber insulated wire core, and can achieve the effects of fire resistance and flame retardant by using filling materials, tapes, cladding materials and metal materials which are not inflammable or have flame-retardant performance.

Description

technical field [0001] The invention relates to a flexible cable, in particular to a silicone rubber insulated fire-resistant flexible cable. Background technique [0002] At present, all kinds of power cables widely used in many domestic buildings are wrapped with a layer of cable insulation. Most of the cable insulation materials contain halogens. This kind of power cable is an extremely dangerous material that transmits flames and expands the scope of the fire. When such insulation materials are ignited, a large amount of dense smoke and highly corrosive hydrogen halides will be produced. The gas endangers human life, endangers equipment and pollutes the environment. Once a fire breaks out in a building, it will endanger life and seriously pollute the environment. Contents of the invention [0003] The object of the present invention is to provide a silicone rubber insulated fire-resistant flexible cable, which can effectively solve the problems of high halogen content...
