Wish FRP outdoor insulation power cross arm won the national invention patent.

Wish FRP outdoor insulation power cross arm 

Traditional power cross arm is commonly two kinds of materials, metal materials and wooden materials.But these two kinds of material with natural flaws.The metal material is not insulated, rain and damp environment have obvious disadvantages, and is easy to rust that increased maintenance costs.Wood materials have insulation advantages, but the wind, sun, rain in the outdoor environment make the use life of the big discount. And it is flammable.
Wishpower Composite Insulator Co.,ltd professional designed and manufacturing invented FRP outdoor insulation power cross arm have overcame the shortcomings of the above two kinds of materials.Use this opportunity that the country vigorously promote new technology of new materials at present, FRP composite Insulation material FRP cross arm was born.PATENT NO.：【ZL 2010 1 0013559.X】
FRP outdoor insulation power cross arm of Wishpower adopt vacumm injection pultrusion process,high temperature secondary curing molding.The power frequency withstand voltage,leakage current and bending failure load,completely meet and exceed the high voltage line porcelain cross arm insulator of the size characteristics and technical conditions.Its characteristic is:
1、Its surface using the surface mat of the polyester, so as to improve the aging resistance of products;
2、Tube inside with polyurethane foaming agent, in order to increase the strength of the cross arm and prevent the rain infiltration;
3、The rectangular tube with a plastic cover on both ends.
4、FRP outdoor insulation power cross arm effectively solves the existing wooden cross arm and iron cross arm poor anticorrosion performance and flame retardant performance, low strength,poor Insulation, such as short service life of faults.
5、This product have the advantage of light weight ,good strength,impact resistance, excellent dielectric properties, as well as good corrosion resistance and heat resistance.
FRP outdoor insulation power cross arm of Wishpower have the shape specifications:angle bar,rectangular tube filled foam,square tube filled foam.also we can design and manufacture according to customer’s requirement.
