Application areas:

Dry-type pluggable composite bushing terminals for AC power transmission, including 66kV and 110kV cross-linked polyethylene insulated power cables.

Product Description

1. The external insulation of the terminal uses silicone rubber sheds, which have excellent dirt resistance, UV resistance, aging resistance and explosion-proof performance;

2. The cable handling length is only 1/6 of that of a conventional outdoor terminal, greatly shortening the installation time;

3. The terminal is plugged into the cable, making installation simple and maintenance easy;

4. The terminal has a completely dry structure, eliminating leakage problems.
