AI Technical Summary
Existing high-voltage cable joint equipment is prone to loosening and slackening when subjected to factors such as gravity and wind, affecting the firmness and safety of the cable connection.
A 110KV cable intermediate joint was designed, which includes a sleeve, a loose sleeve, a wedge groove, a wedge plate, a spring, and a locking assembly. Through the cooperation of the wedge plate and the spring, the cable is firmly clamped and tightened to prevent loosening and slack.
It effectively prevents cable connections from loosening and slackening, ensuring the strength of cable connections and the stability of power transmission, thus improving the safety and efficiency of cable connections.
