Description

Technical Field

[0001] This utility model relates to the field of tension clamps, and in particular to a tension clamp with good compressive strength. Background Technology

[0002] Tension clamps are hardware used to fix conductors to withstand conductor tension and to hang conductors on tension strings or towers. Based on their structure and installation conditions, tension clamps can be broadly divided into two categories. As an indispensable component in power lines, tension clamps come in many types, mainly including bolt type, pre-stirred wire type, and compression type. Among them, bolt type tension clamps are distinguished by their unique fixing method.
