5. ANSI Approve

 

 

Applications:

 

Line post insulators are designed to provide rigid support of conducting cable while offering the maximum resistance to damage from electrical or mechanical events. Horizontal and gain-base line post insulators are often used in applications to avoid the need to install a cross-arm on the pole.

 

 

Competitive advantages:

 

Reasonable insulation structure high reliability of interturn insulation.

Stainless steel flange low magnetic inductivity high resistivity.Small volume light weight.

Convenient transportation and flexible installation.

Low OSS.Low temperature rise.High mechanical strength, strong weather ability.

Outstanding crack resistance.

Low thermal expansion coefficient.
