Development and Application of Universal Hanging line Fixtures for 66-220kV Pointed cross-head
Abstract
For traditional fixtures, replace insulator string conductors as horizontal side hanging points in the linear pole tower of the transmission line. Its versatility is not strong, when using the wire rod and soft slings or carriages can not be shared and other limitations. The development of a Universal Hanging line Fixtures for 66-220kV Pointed cross-head is proposed. First of all, the fixtures span can be adjusted by adjusting the bolts, so as to better avoid all kinds of cross-burden head bolts, and cross on the joint plate and the cross-load bolt. Makes it stable. Secondly, fitting the wire rod directly in the slot at the hanging points at both ends of the mount and lifting with a wire rod depends on the needs of the lifting wire. You can also install a pin rod in the trailer, the carriage set or tight-line soft sling hanging on the pin rod, with the carriage or soft sling lifting. Solved the problem when replacing the insulator with pointed cross-heads, the generality of the wire lifting is not good. And the wire rod and carriage set and soft sling between the lifting tool interchange.
