Composite Suspension Insulator
Good electrical specification,strong mechanical strenght,tensile bending intension of the epoxy glass fiber rod of internalload bearing is double than normal rolled products,8-10times of high strenght porcelain material,can effecti vely improve the reliable of safe operation.
Fine anti-pollution,strong prevent flash accident and the wet withstand voltage and pollution wishstand voltage is 2-2.5times than the same creepage distance porecelain,insulator and not to cleanup,cansafe operate in the serious pollution areas.
Composite insulator series products,which the mechanical performance and electric performance are better than porcelain insulator and the tolerance of safe operation is big and it is the renew product for electric power line.

Product structure Our company specially produces composite insulator for power transmission line, the important structure is made of shed housing, epoxy fiberglass core and metal end fittings. The surface of terminal end fittings is covered with zinc coating(hot-dip galvanization) for corrosion protection. Compared with same type ceramic and glass insulator, silicone rubber insulator has the following advantages:
(1)Small volume, light weight(is 1/7~1/10 times than ceramic insulator in the same voltage), sheds have good elasticity, not broken, convenient transportation and installation, economy.
(2)High mechanical strength. FRP ROD has high tensile strength, which is 5-10 times than ceramic materials, for core is small cross section, which makes the products small size, light weight, high tensile strength, and easy to manufacture more than 300KN large tons insulators.
(3)High antifouling property, good aging resistance performance, the sheds made of silicone rubber injection mold has good hydrophobicity and migration, which makes insulator high anti pollution flashover voltage and good electric corrosion resistance.
(4)Easy installation and maintenance, can greatly reduce outage loss which cause due to maintenance and maintenance charges which cause by manual labor intensity.
(5)Simple production process, short delivery time.
