Application:
Suspension insulator can be used on power transmission and distribution overhead lines. Especially on the extreme high voltage transmission lines,it can not be replaced by other insulators.
Competitive advantage:
Outstanding crack resistance.
Low thermal expansion coefficient.
Convenient transportation and flexible installation.
Reasonable insulation structure high reliability of interturn insulation.
Low OSS. Low temperature rise.High mechanical strength, strong weather ability.
Stainless steel flange low magnetic inductivity high resistivity.Small volume light weight.
Our products are sold all over the world, you can rest assured.
