Lightning Protection Test Ring

Overview

FDL type lightning protection grounding ring is installed in the line insulator load side, specifically used to prevent 1O-20kv overhead insulated wire lightning wire breakage and for the maintenance of the construction of the electricity and grounding device of the new two-in-one products. The current distribution network 1O-20kV and below the overhead lines generally use insulated wire, but the overhead line of the inherent lack of lightning level, but also worrying more than. Because the pole side hanging hanging between the electromechanical grounding ring, fault indicator, anti-arc clip, branch clamp and a series, resulting in messy lines. This product is easy to install, combined, make the line simple and reduce costs for the power sector to provide more cost-effective products, according to the user needs to use stripping type non-puncture-type lightning protection grounding ring model: FDL-50 / 240B; puncture type lightning protection grounding ring model: FDL-50 / 240A.

Technical parameters and selection table

1. Mainly by the insulation shield, compression nut, puncture block, wire clip, lead rod and insulation sleeve and other components.

2. The lead rod and the wire clamp assembly are connected together. When the lightning strike occurs, the arc between the lead rod and the insulator (or the crosspiece) is discharged, so that the freewheeling arc is moved to the arc of the arc. Protect the insulated wire from damage.

3. CFH-50/240 type puncture-type anti-arc clamp with puncture-type tingling structure, easy installation and installation, without stripping insulated wire insulation layer, to avoid the core of water and corrosion, reduce the labor intensity of the operator.

4. can withstand about 5 times the frequency of high current arc burning.
