1.Good electrical specification,strong mechanical strength,tensile bending intension of the epoxy glass fiber rod of internal load bearing is double than normal rolled products,8-10 times of high strength porcelain material,can effectively improve the reliable of safe operation.

2.Fine anti-pollution,strong prevent flash accident, and the wet withstand voltage and pollution withstand voltage is 2-2.5 times than the same creepage distance porcelain insulator,and not to clean up,can safe operate in the serious pollution areas.

3.Small volume,light weight(only 1/6-1/9 of the same voltage grade of porcelain insulator),lightness structure,and it are easy for transportation and installation.the shed has favorable waterproof performance which thewhole structure assures the internal insulation is not wet,not needs to test of prevent insulation and clean up,to reduce the routine maintenanace work capacity.

4.Good sealing performance,strength anti-eectrolytic corrosion,the shed has good anti-ageing,corrosion,proof,performance and the level is TMA4.5 class, is applied to -40℃-±50℃ areas.They have strong resistance to impact and quakeproof performance,good brittle resistance and creep resistance,unbreakable,anti-bend,high anti-bend strength,loading internal force and strong explosion proof,can exchange use of porcelain,glass insulator each other.

5.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.
