Overview
Description:

The cross-section parallel groove clamp is suitable for the non-bearing connection and branch of the overhead power line. It has the characteristics of convenient and flexible installation and large wire diagram. JBTL series copper and aluminum cross-section clamps are used for friction welding or fiber brazing. The insulating cover is used together with the wire clamp to prevent the protection.

Insulating Cover Features:

1.Power frequency withstand voltage: = 4kV for 1 minute without breakdown, no flashover;

2.Insulation resistance: >1.0×1014Ω

3.Ambient temperature: -300C~900C

4.Weather resistance: good performance after 1008 hours of artificial weathering test

5.This insulation cover is suitable for overhead power lines of 10kV and below.
