IEEE C135.90 Insulator Pins for Overhead Line Struction

Insulator Crossarm Pins

Yokelink Insulator Crossarm Pins forged from one piece steel. The base distributes load and provides a firm seat on the Cross arm. Each pin is shipped with assembled hardware. All components are Hot dip Galvanized to meet ASTM A153 specification.

The Crossarm pins are mainly used in transmission lines. It is used to connect crossarms, thereby joining the crossarms. By joining crossarms together, they are made stronger and more resistant to vibration.They are attached in cross arms of overhead transmission lines for supporting and connecting the crossarms by means other than Welding.  They join two crossarms or a cross arm with an insulator mounted on it. It is also put into one crossarm for joining cross arms together.
The cross arm pins have three parts – the crossarm pin base, a crossarm pin body, and the crossarm pinhead. The cross-arm pin base is fitted in an opening of a cross arm.The cross-arm pin body connects the cross arm with another cross arm or a crossarm insulator. The crossarm pinhead is placed on the top end of the cross-arm pin body and holds it into position so that it cannot move outwards.
