Description
Technical field
The utility model relates to a kind of Novel low-smoke halogen-free polyvinyl chloride cable, belongs to field of cable technology.
Background technology
At present, the operational environment of cable is very changeable, often can be faced with adverse circumstances.Under severe operational environment, common cable is owing to cannot bear working temperature and impaired or hydraulic performance decline, cause signal or electric power transfer fault, causing the fault trip of main equipment, stoppage in transit, even damage, there is very big hidden danger in the safe handling for main equipment.And cannot enter in this severe region in normally running, bring extreme difficulty to repair and maintenance work.Above-mentioned situation all brings high risks to the safety of power equipment, economy.
Utility model content
The purpose of this utility model is to provide a kind of Novel low-smoke halogen-free polyvinyl chloride cable, to provide a kind of energy the fire-retardant cable that can use in adverse circumstances, is convenient to use as required, avoids cable impact when adverse circumstances use and disturb.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of Novel low-smoke halogen-free polyvinyl chloride cable, comprise inner restrictive coating, reinforced inserts is provided with in inner restrictive coating, oxygen-free copper conductor is distributed with in reinforced inserts, oxygen-free copper conductor arranged outside has low-smoke non-halogen flame-retardant polyvinyl chloride insulation layer, and low-smoke non-halogen flame-retardant polyvinyl chloride insulation layer arranged outside has barrier layer; Side, barrier layer is provided with reinforcement, and reinforcement is flame-proof silicon rubber layer, and flame-proof silicon rubber layer internal package has high-temperature fibre silk; Inner restrictive coating arranged outside has braid, and braid arranged outside has flame-retardant layer, and flame-retardant layer arranged outside has external sheath layer; Barrier layer adopts mineral matter separator, and weaves one deck fire-retardant fiber band outward at mineral matter separator, extrudes one deck mineral matter separator outward again at fire-retardant fiber band.
Further, braid adopts tough copper wire braid.
Further, flame-retardant layer adopts flame-retardant crosslinking polyethylene materials processing to form.
Further, external sheath layer is polyolefin oversheath.
The beneficial effect of this utility model is: in this utility model, low-smoke non-halogen flame-retardant polyvinyl chloride insulation layer is had in oxygen-free copper conductor arranged outside, anti-flammability and the resistance to acids and bases of cable core can be improved, property indices in adverse circumstances is more excellent, barrier layer adopts mineral matter separator, and weave one deck fire-retardant fiber band outward at mineral matter separator, extrude one deck mineral matter separator outward again at fire-retardant fiber band, further improve its performance; Jacket layer material is thermoplastic polyurethane, and it is ageing-resistant, wear-resisting.This cable combination property is better, has good adverse environment resistant characteristic, extends its useful life, have good result of use, expand its scope of application.
