Abstract

The utility model relates to a novel flame retardation power cable, comprising a first conductor, a second conductor arranged nearby the first conductor, a third conductor arranged nearby the second conductor, and an insulating layer arranged on the outside of the third conductor. Shielding layers are arranged on the outsides of the second conductor and the third conductor of which the outside is equipped with the insulating layer, and foil polyester films are arranged on the outsides of the shielding layers; filling layers are arranged on the outsides of the first conductor and the foil polyester films, armored layers are arranged on the outsides of the filling layers, and outer sheath layers are arranged on the outsides of the armored layers. The novel flame retardation power cable of the utility model has a higher flame resistance, at the same time, is higher in overall intensity and better in use effect.

Description

A kind of New flame-retardant power cable
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of power cable.
Background technology
Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application are increasing.Present common flame retardant cable generally adopts polyvinyl chloride or crosslinked polyethylene as insulation, and sheath material is polyvinyl chloride.This flame retardant cable is owing to its design feature, and refractory temperature is low, and fire-resistant reliability is not strong.Common fireproof control cable does not have very high anticollision function simultaneously.When fire occured, common fireproof control cable can't guarantee that circuit works on, and was difficult to strive for time of more growing for escape and rescue.The flame-retardant layer of general cable all is to adopt glass fiber to fill, glass fiber is filled to cable direct labor and site operation personnel and is brought very large trouble, the workshop workman is flown upward in the full workshop of glass fiber when doing glass fiber filling stranding, get on the skin not only pain but also itch and can not take out, workman's occupational health will be had a strong impact on, and not environmental protection, glass fiber is filled the fire retardancy that has only satisfied cable, and is more harm than good.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of and have than high flame retardant, and bulk strength is higher simultaneously, and result of use is New flame-retardant power cable preferably.
Technical scheme: in order to solve the problems of the technologies described above, a kind of New flame-retardant power cable described in the utility model, it comprises the first conductor, at other second conductor that is provided with of described the first conductor, at other the 3rd conductor that is provided with of described the second conductor, outside described the 3rd conductor, be provided with insulating barrier, outside described the second conductor and outside the 3rd conductor that is provided with insulating barrier, be provided with screen, outside described screen, be provided with the paper tinsel polyester film, outside described the first conductor and paper tinsel polyester film, be provided with packed layer, outside described packed layer, be provided with armour, outside described armour, be provided with external sheath layer.
Described the first conductor, the second conductor and the 3rd conductor are a kind of in copper conductor, aluminium conductor and the tinned copper conductor.
The diameter of described the first conductor is greater than the diameter of the second conductor, and the diameter of the second conductor is greater than the diameter of the 3rd conductor.
Described packed layer is composite material of silicon carbide packed layer or asbestos packed layer.
Described external sheath layer is flexible polyvinyl chloride restrictive coating or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model can be applied to some special occasions, packed layer adopts composite material of silicon carbide, Effective Raise the intensity of product, external sheath layer adopts halogen-free and low-smoke flame-retardant polyolefin sheathed layer, improve the anti-flammability of product, outside screen, set up the paper tinsel polyester film, can strengthen shield effectiveness.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein:
1, the first conductor; 2, the second conductor; 3, the 3rd conductor; 4, insulating barrier; 5, screen; 6, paper tinsel polyester film; 7, packed layer; 8, armour; 9, external sheath layer
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, a kind of New flame-retardant power cable described in the utility model, it comprises the first conductor 1, at described the first conductor 1 other second conductor 2 that is provided with, at described the second conductor 2 other the 3rd conductors 3 that are provided with, outside described the 3rd conductor 3, be provided with insulating barrier 4, outside described the second conductor 2 and outside the 3rd conductor 3 that is provided with insulating barrier 4, be provided with screen 5, outside described screen 5, be provided with paper tinsel polyester film 6, outside described the first conductor 1 and paper tinsel polyester film 6, be provided with packed layer 7, outside described packed layer 7, be provided with armour 8, outside described armour 8, be provided with external sheath layer 9; Described the first conductor 1, the second conductor 2 and the 3rd conductor 3 are a kind of in copper conductor, aluminium conductor and the tinned copper conductor; The diameter of described the first conductor 1 is greater than the diameter of the second conductor 2, and the diameter of the second conductor 2 is greater than the diameter of the 3rd conductor 3; Described packed layer 7 is composite material of silicon carbide packed layer or asbestos packed layer; Described external sheath layer 9 is flexible polyvinyl chloride restrictive coating or halogen-free and low-smoke flame-retardant polyolefin sheathed layer.The utility model can be applied to some special occasions, and packed layer adopts composite material of silicon carbide, Effective Raise the intensity of product, external sheath layer adopts halogen-free and low-smoke flame-retardant polyolefin sheathed layer, improve the anti-flammability of product, outside screen, set up the paper tinsel polyester film, can strengthen shield effectiveness.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
