Abstract
The utility model provides a special two fire-retardant type power cable of fire control, includes high temperature resistant rubber, and the inside parcel side by side of high temperature resistant rubber has two core cables, is connected with the toughness area between two core cables, and the outside of core cable is low smoke flame-retardant band, low smoke flame-retardant inner sheath and steel band armor from inside to outside in proper order, and two center conductors are wrapped up in side by side in the inside of core cable, all wrap up insulating layer and shielding layer outward in proper order in two center conductors, pack fire-retardant material between low smoke flame-retardant band and the shielding layer. The utility model discloses set up high temperature resistant rubber layer outside two core cables, it is fire-retardant to carry out the fire protection to the cable, sets up the toughness area between two core cables, avoids the cable to be pulled apart when drawing when realizing two core cables, convenient to use.
Description
Technical Field
The utility model relates to the technical field of cables, especially, relate to a special two fire-retardant type power cable of fire control.
Background
The cable is usually a cable which is composed of several or several groups of conducting wires, each group is composed of at least two stranded wires similar to a rope, each group of conducting wires is insulated from each other and is usually twisted around a center, the whole outer surface is wrapped with a high-insulation covering layer, the cable has the characteristics of internal electrification and external insulation, the cable is composed of single-stranded or multi-stranded conducting wires and insulation layers and is used for connecting circuits, electric appliances and the like, the existing cable has extremely poor flame retardant effect, when the first cable and the second cable are pulled in a fire hazard, the first cable and the second cable can be burnt, a pulling mechanism is not arranged, a user cannot conveniently pull the first cable and the second cable, the first cable and the second cable cannot be pulled simultaneously, and therefore, a special double-flame-retardant power cable for fire fighting needs to be designed to solve the problem.
Disclosure of Invention
The utility model provides a solve above-mentioned problem, provide a special two fire-retardant type power cable of fire control.
The utility model discloses the technical scheme who takes:
the utility model provides a special two fire-retardant type power cable of fire control, includes high temperature resistant rubber, and the inside parcel side by side of high temperature resistant rubber has two core cables, is connected with the toughness area between two core cables, and the outside of core cable is low smoke flame-retardant band, low smoke flame-retardant inner sheath and steel band armor from inside to outside in proper order, and two center conductors are wrapped up in side by side in the inside of core cable, all wrap up insulating layer and shielding layer outward in proper order in two center conductors, pack fire-retardant material between low smoke flame-retardant band and the shielding layer.
The flexible belt is connected to the top and the bottom of the two core cables.
And the upper part and the lower part of the connecting surfaces of the two central conductors in the core cable are filled with anti-extrusion colloid.
The anti-extrusion colloid is wrapped with a flame-retardant sleeve.
The utility model has the advantages that: the utility model discloses set up high temperature resistant rubber layer outside two core cables, it is fire-retardant to carry out the fire protection to the cable, sets up the toughness area between two core cables, avoids the cable to be pulled apart, convenient to use when realizing that two core cables are drawn simultaneously and get.

Detailed Description
The utility model provides a special two fire-retardant type power cable of fire control, including high temperature resistant rubber 1, 1 inside parcel side by side of high temperature resistant rubber has two core cables, be connected with toughness area 6 between two core cables, the outside of core cable is fire-retardant band 4 of low smoke from inside to outside in proper order, fire-retardant inner sheath 3 of low smoke and steel band armor 2, two central conductor 11 of inside parcel side by side of core cable, two central conductor 11 all wrap up insulating layer 10 and shielding layer 9 outward in proper order, pack fire-retardant material 5 between fire-retardant band 4 of low smoke and shielding layer 9.
The flexible belt 6 is connected to the tops and the bottoms of the two core cables, the flexible belt 6 is made of plastic materials, and under the action of external force, the distance between the two core cables is changed during drawing, so that the flexible belt 6 cannot be broken, and the drawing work is facilitated.
And the upper part and the lower part of the connecting surface of the two central conductors 11 in the core cable are filled with anti-extrusion colloid 8.
The anti-extrusion colloid 8 is wrapped with the flame-retardant sleeve 7.
In the in-process that uses, the flame retardant material 5 of packing between outmost high temperature resistant rubber 1 and the core cable outside and inside for this cable plays high temperature resistant fireproof's effect, connect toughness band 6 between the core cable, in the use, avoided the cable to be qualified for the next round of competitions the condition emergence of tearing, be convenient for draw and get work, two center conductor 11 connect and connect the face upper and lower part packing anti extrusion colloid 8, make the anti extrusion performance difference of each position of cable reduce, extrusion deformation is little during the use, increase of service life.
The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
