ECR Rods

   ECR rods have good stress-corrosion resistant performace as well high temperature resistant performance. ECR rods passed 7200h stress-corrosion resistant test(96h according to standard), suitable for application to all kinds of composite insulators manufacture techniques, especially to injection technique. Advise for application to outdoor insulators in heavy pollution area or acid rais area.

* ECR Rods for composite insulators produced by Jinwang Electrical for many countries, 15 year’s manufacture experience.

* ISO9001:2008, SGS and rods passed tests in domestic, including WHVRI, CEMT, XIHARI.

* Standards: IEC, ASTM, GB, DL.

* Application: Rods operate in high voltage lines up 1000KV.

Features:

*Range:Diameter Φ8-130mm;length:0-13M.

* Type:  E-glass Fiberglass rod (FRP Rod)
