The double-guide T-shaped wire clamp is a kind of tool for connecting the branch wire to the dry wire, which comprises a T-shaped matrix, a trunk slot in the transverse part and a line hole in the vertical part. The inner wall of the trunk groove and the inner wall of the branch hole are provided with a metal liner, and the two metal liners are connected into one body. The upper surface of the longitudinal part of the matrix is fixed by screw connecting the supporting wire pressing screw. In addition, the trunk slot cover is inserted into the trunk slot, and its upper surface is threaded with the dry wire pressing screw to hold the dry wire. The T-shaped upper cover is buttoned with the T-shaped matrix to complete the whole connection process. This design makes the connection only need to carry out the simple work of fastening screws, and the operation is time-saving and labor-saving. The branch wire and the dry wire are in close contact with the metal liner through the pressing screw, and the contact area is large, so the connection is safe and reliable 1. Double guide T-type wire clam6p is not only suitable for the branch connection of 10kV overhead insulated cable, but also suitable for power plant, substation electrical equipment and overhead bus matching use, play the role of insulation protection 2, the design and use of this wire clamp reflects its important role in power transmission and distribution, by providing reliable electrical connection and mechanical support, to ensure the stability of power system Operation.
