ANSI 55-4 porcelain pin insulators,pin type ceramic insulator

ANSI 55-4 porcelain pin insulators have very long service life as because mechanical and electrical properties of ceramic do not be affected by aging, which is one of pin type ceramic insulator and ensures long life span and protect power line.

ANSI 55-4 porcelain pin insulators strength:
ANSI 55-4 porcelain pin insulators mechanical strength test should be done under apply certain electricity, that is to do combined mechanical and electrical strength tests. ANSI 55-4 pin insulators are normally designed in 12.5kN, according to insulator application and service conditions, the pin type ceramic insulators strength are designed in 4kn, 8kn, 6kn, 7kn, 9kn 10kn or 13kn.

Ceramic pin type insulator / pin type ceramic insulator models:
Models are the insulator symbols to easy remember, each model insulator can be designed in different sizes. Customers can choose the different pin type insulator in accordance with these models.  ANSI 55-4 porcelain pin insulators are one of ANSI 55 series porcelain pin type insulator, which also include ANSI 55-1, ANSI 55-2, ANSI 55-3, ANSI 55-4, ANSI 55-5 and ANSI 55-6.
