​we can provide short stud or long bolt for insulator assembly .

Applications:

The ANSI 57-4 porcelain line post insulators are used on distrbution lines  with voltage up to 55kV. These insulators are commonly installed vertically on metal base to support the
conductor . tie top procelain can hold conductor firmly and suitable for different size of conductors.

Competitive Advantage:

high strength aluminum porcelain C-130 is used for insulation body .

the insulator have very light net weight yet high mechanical strength .​

​the insulator have excellent self-clean character , much easier for maintenance..
