AI Technical Summary
Existing cable distribution boxes are prone to shaking when cables are pulled, leading to sealing failure, rainwater leakage, affecting the firmness of cable connections and corroding internal cables.
The sealing assembly of the underground branch box includes a sealing body and a cold shrink tube. Through the cold shrink tube and sealing ring in the sealing cavity, combined with the filling of sealing resin, the stable connection between the cable and the sealing assembly and the anti-seepage performance are ensured.
It improves the connection strength between the cable and the sealing components, prevents rainwater leakage, and enhances the sealing and protective performance of the cable branch box.
