Abstract
The utility model relates to a kind of rat-and-ant proof environment-friendly type orbit traffic direct current power cable, described cable comprises conductor, insulating barrier, water blocking layer, oxygen barrier layer and outer jacket, described conductor is stranded conductor and outer extruded insulation layer, described insulating barrier is outward water blocking layer, water blocking layer extrudes oxygen barrier layer outward, and oxygen barrier layer extrudes outer jacket outward; Described water blocking layer is made up of waterstop and aluminum plastic belt bonding sheath.This cable rat-biting proof protection reaches more than 98%; termite-proof moth erosion protection reaches the more than 2 grades of national standard; waterproof and uvioresistant are effective, not only have the characteristic of low-smoke bittern-free highly fire-proof, good humidity resistance; good environmental-protecting performance; also extend the useful life of cable, reduced cable cost, diverse in function; nontoxic, science environmental protection.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of rat-and-ant proof environment-friendly type orbit traffic direct current power cable.
Background technology
Along with the high speed development of urban rail transit in China cause, the demand of cable for rail transit also constantly increases.The infringement of nibbling that a lot of areas of China often can run into the animal such as mouse and termite causes the subway generation of the phenomenon of cable bad, makes the conductor wire core of subway in cable form short circuit power cut, causes huge economic loss.The rat-and-ant proof method that at present subway is taked with cable product mainly contains two kinds of chemical method and Physicals.Chemical method adds chemicals exactly in cable jacket material, with toxicology poisoning mouse ant; Physical is exactly to adopt the material that hardness is higher to make cable cover(ing) as nylon, modification gather Halogen alkene.Along with the reinforcement of people's environmental consciousness, above-mentioned chemical method and physics method rat-and-ant proof cable are serious to natural pollution, and useful life is short and cost is high, there is no good waterproof antiultraviolet effect, function singleness, the demand of the society that is difficult to meet high speed development to cable feature.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of rat-and-ant proof environment-friendly type orbit traffic direct current power cable, prevents that cable for rail transit from being nibbled by the animal such as mouse and termite.
For realizing above object, by the following technical solutions:
A kind of rat-and-ant proof environment-friendly type orbit traffic direct current power cable, described cable comprises conductor, insulating barrier, water blocking layer, oxygen barrier layer and outer jacket, described conductor is stranded conductor and outer extruded insulation layer, described insulating barrier is outward water blocking layer, water blocking layer extrudes oxygen barrier layer outward, and oxygen barrier layer extrudes outer jacket outward; Described water blocking layer is made up of waterstop and aluminum plastic belt bonding sheath.
Described insulating barrier adopts irradiation crosslinked polyolefin insulating material.
Described oxygen barrier layer adopts polyolefin oxygen barrier material.
Described outer jacket adopts the low smoke halogen-free flame-retardant polyolefin of rat-and-ant proof antiultraviolet.
The utility model beneficial effect:
Adopt irradiation crosslinked polyolefin insulating material to do insulating barrier, not only ensured the electrical property of insulation, thereby improved the mechanical and physical performance of cable product, its temperature tolerance, freedom from cracking, ageing-resistant, useful life, the performance such as fire-retardant.
Water blocking layer is by adopting wrapped waterstop and aluminum plastic belt bonding sheath to combine, and block-water effect is good.Make cable not only there is rat-and-ant proof anti-ultraviolet function, also improved waterproof and dampproof performance, nontoxic, science environmental protection.
Adopt high flame retardant oxygen barrier layer structure, can make cable reach the requirement of fire-retardant A level, anti-flammability is high.
Sheath has adopted rat-and-ant proof antiultraviolet low-smoke halide-free fireproof composite polyolefine material, reduce production cost, improve cable waterproof anti-ultraviolet function, overcome the defect of cable jacket in the past, can not only rat-and-ant proof, can also reduce the pollution to environment and soil, improve electric property and the useful life of cable, made cable there is protection against rodents, anti-ant, Halogen, low cigarette, low toxicity, uvioresistant, fire-retardant feature, diverse in function, reduce and pollute, science environmental protection.
