Description

Fire-fighting double-flame-retardant power cable Technical Field The utility model relates to the technical field of cables, in particular to a double flame-retardant power cable for fire protection. Background The cable is a cable similar to a rope and formed by twisting several or several groups of wires (at least two wires in each group), the wires in each group are mutually insulated, the cable has the characteristics of internal power supply and external insulation, the cable is divided into fire-fighting cables and the like, and at present, fire-proof cables are needed in places with high requirements on fire safety conditions such as domestic high-rise buildings, large-scale shops and high-rise residential buildings. At present, most of the existing power cables for fire protection are simple in structure, single in function and poor in flame retardant effect, and most of the outermost layers are provided with fireproof protection layers, so that the strength is low, and damage can be caused to the fireproof layers on the outer layers of the fire-fighting cables when the working environment is severe or the ground is too many in broken stone, so that the normal use of the fire-fighting cables is affected. Disclosure of utility model The utility model aims to solve the problems that the existing fire-fighting power cable is simple in structure, single in function and poor in flame-retardant effect, a fireproof protection layer is arranged on the most outermost layer, the strength is low, and the fire-fighting power cable is damaged due to the fact that fire-fighting layers on the outer layer are damaged due to severe working environment or excessive ground broken stone, so that the normal use of the fire-fighting cable is affected. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a fire control is with two fire-retardant power cable, includes cable body and anticorrosive rubber cover, cable body's surface has the fire prevention mica tape around the package, and the outside of fire prevention mica tape is crowded to be wrapped with the oversheath, and the surface integrated into one piece of oversheath has a plurality of protection strips, the anticorrosive rubber cover contains the wire net, and anticorrosive rubber cover parcel is in the outside of protection strip, and the surface coating of anticorrosive rubber cover has fire prevention coating, and a plurality of fixed clamps have been cup jointed in the outside of anticorrosive rubber cover. Further, the cable body comprises a plurality of groups of copper conductors, and an insulating layer is extruded outside the copper conductors. Further, a shielding layer is extruded on the outer side of the insulating layer. Further, the outside of shielding layer parcel has the armor. Further, the outer sides of the armor layers are extruded with filling layers. The beneficial effects of the utility model are as follows: 1. The cable body is enabled to have high fire resistance and heat insulation performance through the fireproof mica tape, so that a good fireproof effect is achieved inside, the fireproof effect is achieved outside through the fireproof coating, and accordingly a double-layer fireproof and flame-retardant effect is achieved, and normal use of the cable is guaranteed. 2. The cable body has anti-corrosion performance through the anti-corrosion rubber sleeve, abrasion is reduced, and the steel wire mesh increases the tensile strength and the pressure resistance of the cable body, so that the service life of the cable is prolonged. Drawings Fig. 1 is a schematic perspective view of a dual flame retardant power cable for fire protection according to the present utility model; FIG. 2 is a schematic cross-sectional view of a dual flame retardant power cable for fire protection according to the present utility model; fig. 3 is a schematic diagram of a part of an enlarged structure of a dual flame retardant power cable for fire protection according to the present utility model. The fire-proof protective sleeve comprises a protective strip, a fire-proof mica tape, a filling layer, an armor layer, a shielding layer, an insulating layer, a copper conductor, a corrosion-proof rubber sleeve, a steel wire mesh, a fire-proof coating layer, a fixing clamp and a fixing clamp.
