Description

Lightning arrester insulating sheath

Technical Field

The utility model relates to the technical field of lightning arrester sheaths, in particular to a lightning arrester insulation sheath.

Background

The arrester is connected between the cable and the ground, is connected with protected equipment in parallel generally, can effectively protect communication equipment, acts once abnormal voltage appears, plays a role in protection, does not act when the communication cable or equipment operates under normal working voltage, is regarded as circuit breaking for the ground, and is connected with wires at the end part of the arrester in the using process, so that the arrester can work normally.

In order to effectively protect the joint of the lightning arrester, an insulating sheath is usually sleeved at the joint, the insulating sheath can effectively prevent the damage of the power equipment caused by various reasons to the original exposed wiring terminal of the power equipment, so as to avoid huge economic loss, but it can be seen that the insulating sheath at the joint of the lightning arrester is usually directly and loosely sleeved at the wiring terminal, although the insulating sheath cannot fall off from the wiring terminal, since the bottom of the insulating sheath is not effectively attached to the surface of the end of the lightning arrester, if the weather of wind and rain is met, rainwater enters from the bottom of the insulating sheath, once the time is long, the wiring terminal is still affected greatly, and the wiring terminal of the lightning arrester is easy to fail
