Abstract
A high flame-retardant low-smoke environment-friendly low-voltage cable comprises an insulating layer arranged on the periphery of a main core, two pairs of conductors are distributed in a cross shape by taking the main core as the center, the insulating layer is arranged on the periphery of each conductor, steel belts are arranged on the peripheries of the two pairs of conductors, high flame-retardant glass fibers are filled between the peripheries of all the insulating layers and the inner peripheries of the steel belts, and sheaths are arranged on the peripheries of the steel belts; the utility model discloses not only fire-retardant, fire resistance is good, and mechanical strength is excellent, and chemical stability is good moreover, and the environmental protection is pollution-free.
Description
Technical Field
The utility model relates to a power cable field especially relates to a low cigarette environmental protection low tension cable of high fire-retardant.
Background
Modern life relies on electric power more and more, the cable is indispensable as the circuit of power transmission in the modern building, along with high-rise building, hospital, hotel, station and airport etc. constantly increase, and subway, urban rail transit, the construction of large-scale public facility, the importance of fire safety also shows day by day, the laying amount of cable increases at double in the building, the building begins to adopt fire-resistant flame retardant cable to supply power the imperative, as fire-resistant cable, the flame retardant coating is under flame or high temperature condition, not only fire-retardant fire-resistant, but also have higher adiabaticity in order to guarantee that external high temperature does not harm internal insulation, guarantee the integrality of circuit in certain time after catching fire of cable.
In view of the above, a high flame retardant, low smoke and environment friendly low voltage cable has been developed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming not enough among the prior art, provide a low cigarette environmental protection low tension cable of high fire-retardant, not only fire-retardant, refractiveness is good, and mechanical strength is excellent, and chemical stability is good moreover, and the environmental protection is pollution-free.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a high flame-retardant low-smoke environment-friendly low-voltage cable is composed of: the cable comprises a conductor, an insulating layer, high-flame-retardant glass fiber, a steel belt, a sheath and a main core; the periphery of main core sets up the insulating layer, and two pairs of conductors use main core to be the cross distribution as the center, and the periphery of conductor sets up the insulating layer, and the periphery of two pairs of conductors sets up the steel band, the periphery of all insulating layers and the interior week of steel band between fill high fire-retardant glass fiber, the steel band periphery sets up the sheath.
The conductor is fan-shaped.
The sheath adopt heat-resisting low cigarette material PVC material.
The utility model has the advantages that: the utility model discloses a conductor intussuseption is filled with high fire-retardant glass fiber for the conductor can transmit the electric energy at high fire-resistant and high fire-retardant condition safe and reliable ground, the utility model discloses not only fire-retardant, fire-resistant good, mechanical strength is excellent, and chemical stability is good moreover, and the environmental protection is pollution-free.
Drawings
The present invention will be further explained with reference to the accompanying drawings:
FIG. 1 is a schematic view of the assembly structure;
in fig. 1: the cable comprises a conductor 1, an insulating layer 2, high-flame-retardant glass fibers 3, a steel belt 4, a sheath 5 and a main core 6.
Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings:
the periphery of main core 6 sets up insulating layer 2, and two pairs of conductors 1 use main core 6 to be the cross distribution as the center, and the periphery of conductor 1 sets up insulating layer 2, and the periphery of two pairs of conductors 1 sets up steel band 4, the periphery of all insulating layers 2 and the interior week of steel band 4 between fill high fire-retardant glass fiber 3, 4 peripheries of steel band set up sheath 5.
The conductor 1 is in a fan shape.
Sheath 5 adopt heat-resisting low smoke material PVC material.
