Description
Technical field
Technical field of electric wires and cables is the utility model is related to, specially a kind of long-life electric wire cable.
Background technology
For in general PVC insulated electric conductors service life at 15 years or so, the heatproof air aging performance of insulating barrier was poor, makes for a long time
With insulating barrier aging can be caused to rupture, easily cause the security incidents such as puncture short.And current electric wire insulation layer uses Halogen
Low-smoke flame-proof polyolefin material, because adding substantial amounts of aluminium hydroxide and flame retardant of magnesium hydroxide in material prescription, this two kinds of things
Matter (because being thermally decomposed into aluminum oxide, magnesia and water) moisture-sensitive and water suction, have a strong impact on the insulating properties of product.
Traditional architecture uses individual layer polyvinyl chloride insulation with electric wire, has the following disadvantages：Operating temperature (70 DEG C) and short circuit
Temperature (160 DEG C) is low, therefore ageing properties are poor, easy aging, there was only 20-30 service lifes under regular service conditions, makes
Service life is also shorter if it excess load or extreme climate situation be present in.In recent years, trigger due to electrical wiring aging
Fire incident has increased trend year by year, and the portion of building is lived for this and has put into effect two building wires and the recommendatory mark of cable for building
It is accurate, it is desirable to which that building wire service life is not less than 70 years, synchronous with Building life cycle, it is clear that using traditional architecture electric wire
It is that can not meet this requirement.Additionally due to polyvinyl chloride insulation is polar material, insulaion resistance is high and easy moisture absorption,
Electric wire once makes moist, and easily produces electric leakage, or even lead to a disaster；Polychloroethylene insulation material can also produce a large amount of poisonous when burning
Pernicious gas, smog, very big threat is caused to personal safety and property.Therefore exploitation is synchronous with Building life cycle, and green,
The long-life electric wire of environmental protection, can effectively prevent electric wire premature aging, reduce the Probability of fire, significant.
In order to solve the above problems, current wire structure is complex, is provided with multilayer dielectric layer and multilayer screen layer,
But this considerably increases the production technology of electric wire and production cost.
The service life of electric wires many at present is shorter, and broken string, protection occur during much time using
The situation that layer corrosion comes off.
Utility model content
