Low Pressure Seal Offs

According to the different shapes, there is another type called Y clevis. It’s because the structure is like letter “Y”. On the one hand of the ball clevis is a ball head. On the other hand, there is a steel pin or hex bolt going through the two holes of the ball clevis. So that, there is space for the U clevis to connect the ball clevis.

Pole top bracket is made to permit mounting on wood poles by two 16mm diameter bolts vertically spaced 203mm center to center. One of the bracket mounting holes is slotted to permit slight variations in mounting bolt spacing. The insulator mounting surface is at a height approximately 125mm above the top bracket mounting hole.

A pole band is designed to suitable for use on poles of pole top diameter 150mm to 280mm. We have supplied a diameter of 155mm, 185mm, 230mm, and so on.

The pole band has a stay tension strength not exceeding 29kn. While the result will be different if a gain grid or some other device is used to transfer the shear load from the pole bolt.
