Cable insulation material field in our country

Cable insulation materials, especially high voltage cable insulation materials commonly used in plastics polyethylene, polypropylene, PVC, and other special plastic.
1. PE class cable insulation material
Polyethylenes cable insulation material high insulation resistance, voltage resistance performance is good, especially the dielectric constant and dielectric loss is small, the influence of temperature and frequency is small, and it has good physical and mechanical properties and water resistance, solvent resistance, drug resistance. Related patents on PE class cable insulation materials mainly involved polyethylene cable insulation materials on the flame retardancy, water tree electrical resistance, anti-aging, oxidation and resistance against wear and charred aspect as well as the effect of preparation technology on the improvement.
2. Polypropylene cable insulation material
Polypropylene class cable insulation material density is the smallest and lightest, its heat resistance and mechanical strength is better than that of PE, especially the high frequency characteristics, the modified flame retardant is tasted, can be obtained from foaming.
3. PVC insulated cable material
PVC insulated cable material resistant to high voltage and insulation resistance, flame retardant, oil proof, weather resistance, chemical resistance, corona resistance and water resistance performance, but its dielectric constant and dielectric loss is bigger, cold resistance is poorer, is often used to 1kv and below the wire and cable, semiconduction shielding and all kinds of wire and cable sheath.
4. Other cable material
In addition to the three general plastic formation of the cable insulation materials, fluorine plastic, polystyrene, polyimide and polyamide, polyester and other plastics is also used as cable materials, these materials have a certain feature is also used in some special occasions, such as ptfe, its thermal performance is good, continuous working temperature is 250 ℃, and electrical properties, flame retardancy is better also. But since they don't melt at high temperature, which is unfavorable for processing, and high mechanical strength is not enough, so often as the second polymer and three general plastic copolymerization or blending to improve the properties of the insulated cable materials, through special processing method, a small, separate and high frequency cable insulation materials used for high temperature wire.

In addition, in the field of application for a patent in China is more dispersed, patent quality remains to be improved, there are few enterprises or scientific research institutions formed by a series of interlocking technical patent protection. Anytekabel Co.,Ltd.(www.anytecable.com) the cable has passed CCC, CSA, TUV, CE...Such as certification. At the same time made the patent management system, fully mobilize the employees' innovation enthusiasm.
