螺栓紧固式负荷转移线夹Bolt-On Load Transfer Clamps

技术领域 technical field

本实用新型涉及一种引流线夹的改进,具体地说是一种螺栓紧固式负荷转移线夹。主要应用于带电更换设备过程中,转移负荷挂接引流线。 The utility model relates to an improvement of a drainage wire clamp, in particular to a bolt-fastened load transfer wire clamp. It is mainly used in the process of replacing equipment with electricity, transferring loads and hooking up drainage lines.

During live work, it is often necessary to transfer loads to replace faulty equipment. In order to ensure the continuous power supply of the line, the use of the drain line is very frequent. In the past, the drainage wire used a sleeve-type clamp. During the hooking process, the sleeve needs to be unscrewed to realize the connection and fastening of the drainage wire and the wire. It is very inconvenient for the operator to wear insulating gloves during the operation, and the movement range is relatively large. Increased the unsafe factors and difficulty of operation of operators in the operation process.
