Due to the different cross-sectional areas of the wires of the main line, the J-type clamps are classified into A, B, C types, and the size is small to large. Stage a is for conductors with cross-sectional areas 702, 952, 1202, stage B is for conductors with cross-sectional areas 1502, 1852, and stage C is for conductors with cross-sectional area 2402. In order to ensure that the power users continuously use the electricity, the connection work of the lead wires of the branch lines and the lead wires of the main line is realized by installing the J-shaped wire clamp in a live working mode. When the insulating bucket arm vehicle can not reach the working position, live working personnel need climb the live wire pole, keep certain safe distance with electrified wire, carry out the installation of J type fastener through insulating bar.
In the prior art, there are two types of tools for installing a J-type wire clamp:
1. through the clamping device unanimous with J type wire clamp wire casing direction, fix J type fastener on insulating bar's instrument head, there are two live working personnel on the pole, first electrician lifts up the insulating bar who passes through J type fastener with having installed the lead wire, the mounted position that makes trunk conductor enter into, the second electrician inserts the lead wire mounted position of J type fastener through insulating bar with the lead wire, first electrician passes through the built-in anchorage bar of action bars and fastens J type wire clamp bolt.
