Abstract
The utility model relates to a novel fireproof silicone rubber insulation low-pressure power cable. The novel fireproof silicone rubber insulation low-pressure power cable comprises a cable core and an outer sheath, wherein the cable core internally has multiple leads formed by conductors, the conductor is formed by intertwisting copper wires and then wrapping the intertwisted copper wires with an insulation layer, flame retardation filler is arranged among the multiple leads, and a flame retardation belting layer, a lining layer and a metal armor layer are arranged between the cable core and the outer sheath in order. The novel fireproof silicone rubber insulation low-pressure power cable has great flame retardation performance and fireproof performance, so the cable is not burned to spread even if a fire disaster occurs, and the cable still remains great insulation performance, can work in a relatively long term, is helpful to carry out rescue work and reduces personal casualty and property loss to the greatest extent.
Description
Technical field
The utility model relates to a kind of lv power cable, especially a kind of Novel fire-resistant lv power cable.
Background technology
For improving the lsafety level of electric wiring, fire-retardant, the fire resistance that are used for the lv power cable of electric wiring seem more and more important.The structure of existing lv power cable and performance are difficult to adapt to fire-retardant, the fire-resistant requirement when using in electric wiring.
Summary of the invention
In order to overcome the deficiency of existing lv power cable, the purpose of this utility model provides a kind of Novel fire-resistant silicon rubber insulation lv power cable.
A kind of Novel fire-resistant silicon rubber insulation lv power cable that the utility model provides, comprise cable core and oversheath, have several wires being consisted of by the stranded conductor outer cladding insulating barrier that forms of copper wire in the cable core, between several wires, be provided with fire-retardant filler, between cable core and oversheath, be provided with successively fire-retardant belting layer, inner covering, metal armouring layer.
The beneficial effects of the utility model are: have good fire-retardant, fire resistance, in case run into fire, cable can propagating combustion, still can keep good insulation property, can work the long period, help carrying out of rescue work, reduce as far as possible casualties and damage to property.
