11-33KV porcelain pin insulator
11-33KV porcelain pin insulator Definition：
Porcelain pin insulator is a kind of porcelain insulator, and it is made up of one or several porcelain parts by cement. Pin insulators play a supporting role to the wire and insulation in power distribution lines, installed on the crossarm of electrical poles via insulator pin.

The main usage of 11-33KV porcelain pin insulator:
11-33KV porcelain pin insulator is mainly used on transmission overhead lines and distribution lines, the main usage is to insulate and support the conductors.
The applied voltage of porcelain pin insulator:
Pin insulator applied voltage: 6KV, 10KV, 11KV, 12KV, 15KV, 22KV, 24KV, 25KV, 33KV, 35KV, 36KV
Some of these voltage means rated voltage such as 11kv, 22kv, 33kv, but some of the voltage means system voltage such as 12KV, 24KV, 36KV. So, 11-33KV porcelain pin type insulator means the pin type insulator classified by rated voltage.
11-33KV porcelain pin insulator Cantilever Strength：
Pin insulator should withstand certain cantilever strength, and this is the main parameter of high voltage insulator. ANSI standard requires 11KN, 13KN failing load strength, and BS standard and IEC Standard only requires 10KN.
