Distribution porcelain disc suspension insulator
Distribution porcelain disc suspension insulator is most commonly used by many countries. And it is one of the products of Orient Power, which is a professional insulator supplier. We can manufacture the insulator to meet the requirement of the clients. Except the distribution porcelain disc suspension insulator, the 120KN Porcelain disc suspension insulator and 120KN composite suspension insulator and 160KN composite suspension insulator are also our product.
The function of each parts of distribution porcelain disc suspension insulator:
Distribution porcelain disc suspension insulator shall be furnished with a hump-type cotter key, which can prevent the cotter bolt being pulled out of the insulator cap during the normal handling and use. So the material of the cotter key is critically important.
The material of the cotter key is usually bronze, brass, austenitic stainless, or aluminum. Right material can promise good function of the Distribution porcelain disc suspension insulator.
