Abstract

The utility model discloses a corrosion-resisting inflaming retarding power cable, comprising conductors, inner wrapping tape layers, insulators, filler, an outer wrapping tape, an inner sheath, an armor layer, a bituminous coating and an outer sheath. The conductors use a structure of bunch strand. The inner wrapping tape layers are extruded outside the conductors. The insulators are extruded on polyester tapes, and using steam crosslinking, three insulating wire cores are stranded with the filler. The armor layer is extruded outside the inner sheath. The power cable has good mechanical strength and flame retardant property. In addition, galvanized steel strip interlocking with armor improves longitudinal tension of the cable, and has a function of electromagnetic shielding.

Description

A kind of corrosion-resistant flame-proof power cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of corrosion-resistant flame-proof power cable.

Background technology

Along with The development in society and economy, the electric wire consumption increases rapidly, the electrical fire accident also takes place again and again, people are from the heaviness lesson of electrical fire accident, recognize gradually in some important places, as electric equipments in the circuits such as naval vessel, production platform, petroleum chemical enterprise, large-scale power station, large-scale command and control center and skyscraper, underground structure, tunnel, subway, it is very important keeping being in stable running status in the certain hour under fire condition.Along with progress of science and technology, also more and more higher to the requirement of cable, require cable to have corrosion-resistant, oil resistant gas, do mechanical strength and performance such as fire-retardant, and existing cable for petroleum flat is difficult to reach above-mentioned requirements.

Summary of the invention

In order to overcome the defective of above-mentioned prior art, the purpose of this utility model provides a kind of good anticorrosion, fire-retardant that has, the corrosion-resistant flame-proof power cable of the advantage of mechanical strength height, good bending property.

The utility model takes following technical scheme to realize: a kind of corrosion-resistant flame-proof power cable is made up of conductor, interior belting layer, insulator, obturator, outer band, inner sheath, armour, bituminous coating and oversheath.The structure that tangles is restrainted in described conductor employing, and described conductor outside is extruded with described interior belting layer, and described insulator is extruded on the polyester belt, and adopts vapor crosslinking, and three eradication edge cores and described obturator are stranded together, and described inner sheath is extruded with described armour outward.

The utlity model has following beneficial effect in sum:

1, good anticorrosion, fire-retardant, mechanical strength height, good bending property;

2, the galvanized steel strip lock armo can improve the cable longitudinal pulling force, also has the effect of electromagnetic shielding.
