Description

Anti-cryocable

Technical field

The utility model relates to cable, relates in particular to a kind of anti-cryocable.

Background technology

Wind energy is one of following green energy resource technology as a kind of clean energy resource, and wind power generation system is arranged on the bigger area of wind-force usually.And the bigger area of wind-force is usually located at the high latitude zone, and temperature is lower equally, all is arranged in the environment that work temperature is lower than-25 ℃ such as, most of wind generator systems of China.The low-temperature working environment causes very big influence to peripheral auxiliary system, the especially cable of wind generator system.

Use common cable to serve as transmission cable in a lot of wind power generation systems at present, the design applied environment of common cable is a normal temperature environment, is not low temperature environment, and therefore the useful life and the performance of common cable all can be subjected to very big influence under low temperature environment.

The utility model content

The utility model is intended to propose a kind of anti-cryocable, has heat-insulation layer to adapt to the low temperature environment that wind power generation system is used.

According to the utility model, a kind of anti-cryocable is proposed, comprising:

Conductor, conductor are positioned at the center of cable;

The insulating sleeve layer is coated on outside the conductor, and the insulating sleeve layer is a thermoplastic elastomer (s);

Heat-insulation layer is coated on outside the insulating sleeve layer.

Conductor is zinc-plated soft copper conductor.Heat-insulation layer is the irradiation neoprene.

Anti-cryocable of the present utility model provides the heat-insulation layer of irradiation neoprene, can be effectively the insulating sleeve layer and the conductor of its inside be incubated, and avoids the aging performance that occurs owing to low temperature.

Description of drawings

Fig. 1 has disclosed the structure chart according to warp resistance cable of the present utility model.

Embodiment

With reference to figure 1, Fig. 1 has disclosed the structure chart according to anti-cryocable of the present utility model.This anti-cryocable has three-decker, is respectively from the inside to the outside: conductor 10, insulating sleeve layer 20, heat-insulation layer 30.

Conductor 10 is positioned at the center of cable, and conductor 10 is zinc-plated soft copper conductor, and enough conductivity and mechanical tenacity are provided.Insulating sleeve layer 20 is coated on outside the conductor 10, and insulating sleeve layer 20 is a thermoplastic elastomer (s).In one embodiment, insulating sleeve layer 20 is irradiation second third elastomeric insulating material.Adopt irradiation second third elastomeric insulating material to make insulating barrier, have elasticity and ductility preferably, reliable insulation property are provided simultaneously.Heat-insulation layer 30 is coated on outside the insulating sleeve layer 20, and the effect of heat-insulation layer 30 is to provide insulation to parcel conductor and insulating sleeve layer within it, with the cryogenic applications environment of reply wind power generation system.In one embodiment, heat-insulation layer 30 is the irradiation neoprene.The irradiation neoprene has the low-temperature working characteristic, is difficult for taking place the phenomenon of embrittlement or cracking at low temperatures.

Anti-cryocable of the present utility model provides the heat-insulation layer of irradiation neoprene, can be effectively the insulating sleeve layer and the conductor of its inside be incubated, and avoids the aging performance that occurs owing to low temperature.
