Embodiment Construction

[0005] The figure includes 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 wire core 1, a refractory layer 2, and an insulating layer 3 in sequence from the inside to the outside. The inside of the cable outer layer is from the inside to the outside. The outer layer is a flame-retardant tape 4 and a sheath layer 5 in turn, 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 number of cable inner cores in the outer layer of the cable is one or more, generally three, four or five are selected. The conductive wire core has two or more layers, each layer has several wire groups with the same cross-section, each wire group has several conductor monofilaments, and the layers are twisted in opposite directions. The conductive co...

Abstract

The invention relates to a fluorine plastic insulated fireproof control cable which comprises an inner cable core and an outer cable layer coated outside the inner cable core, wherein the interior of the inner cable core sequentially comprises a conductor wire core, a fireproof layer and an insulating layer from inside to outside; the interior of the outer cable layer sequentially comprises a flame retardant coating belt and a jacket layer from inside to outside; and a gap between the outer cable layer and the inner cable core is internally provided with a flame retardant filler. Both the insulating layer and the jacket layer of the cable are made of fluorine plastic, and the cable is a chemically stable, flame retardant, halogen free and environmental-friendly material resistant to high and low temperature, fire and corrosion. During combustion, the cable release no harmful gas and smog, can be used in hostile and special environment at about 200 DEG C and has clean and smooth appearance, weather proofing, chemical corrosion resistance, good stability, high and low temperature resistance, low smog, no halogen, environmental protection and flame retardance.

Description

technical field [0001] The invention relates to a control cable, in particular to a fire-resistant control cable with fluoroplastic insulation. 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 task of the patent of the present invention is to provide a fluoroplastic insulated fire-resistant control cable, which can effectively solve the problems of the contr...
