■An overview of the

FDL type lightning protection test electrical grounding ring is a kind of installation in the load side line insulator, specifically designed to prevent 10-20kv overhead insulated wire lightning strike and used to repair the check during the construction of electricity and grounding device of new type of seal products. 10-20kv and below the current distribution network is generally used to overhead line insulation wire, but lightning resisting level of congenital deficiency of aerial insulation line, and disturbing. Because of the check electrical grounding pole side often hang ring, fault indicator, arc clamp, branch clamp and so on a series of line messy indecent. This product is easy to installation, 2 for one, line is concise and reduce costs, to provide more cost- effective products to power sector, according to user needs with peeling of the piercing type electrical grounding ring type risk prevention check-upis: a 50/240 FDL b; The piercing type anti ?

■Specifications and performance parameters

■Model specification

■The main items

1、In thunderstorm season to line before and after inspection, check whether the product is in a normal state of installation, or is damaged, should be adjusted or replaced when necessary.

2、As in the line between installation of relay protection device, with automatic reclosing adjust good parameters can effectively reduce the line power frequency.

■Structural characteristics of

1, mainly by the insulation shield, gland nut, briquetting, clamp and multi-purpose insulation ring, etc.

2 with organic composite materials, insulation shield hoe-scr-r-ritch, with good insulation performance, ageing resistance and flame retardant properties.

3, multi-purpose ring is the arc rod and check electrical grounding ring parts together. When lightning occurs, are bar insulator discharge between metal parts, and make the stream power frequency arc moved to the arc burning on the rod, thus protecting insulated wires from damage. When maintenance construction, can be used to test electrical and temporary grounding device.

4, this product has many USES, installation is convenient, reliable performance, can greatly reduce the labor intensity of operators.

5, tolerated about five big power frequency current arc burning.
