概述

该型避雷器采用合成外套作为外绝缘并采用树脂构成一种特殊的加强结构，使其具有良好的抗弯曲强度。这种集常规避雷器和绝缘子二者功能为一体，具有复合功能的结构形式和新颖的避雷器，总体上达到国际先进水平。

Overview

This type  of arrester  uses  synthetic coat as outer  insulation and  resin to form a  special  strengthening structure,  so  that  it  has  good  bending  strength.  This  product, which  integrates  the  functions  of  both conventional arrester and insulator, has the structural form of composite function and novel surge arrester, and generally reaches the international advanced level.

Product feature

1. The core and shell of the arrester are molded into a dense whole without cavities, eliminating moisture absorption caused by respiration and fundamentally eliminating accidents caused by moisture in the arrester chip;

2. The arrester adopts a special strengthening structure, so that it has good mechanical properties, which can be used as an insulator;

3. The  synthetic  shell  of the arrester  is  made  of  silicone  rubber  material,  which  makes  it  strong  in  anti-fouling performance and has good anti-explosion performance, with light weight and long service life;

4.  The  arrester  is  designed  and  produced  according  to  the  m-grade  heavy  pollution  resistance,  the  minimum creepage ratio distance of the insulation coat is 25mm / KV, and the creepage distance is 320mm;

5. The overall structure of the arrester is optimized and designed with a sorting function.

(1) There are both grounding memes, which can meet the needs of power detection and grounding, and can simplify the tower installation.

(2) Special reinforced structure, which gives it good mechanical properties and can be used as a pillar insulator.

(3) The connecting terminal  row  can  be  segmented  cable  fault,  narrow  the  power  outage  range,  and  have  the function of cutting off the switch.

The  arrester  adopts  the  full  insulation  design,  which  can  effectively  avoid  the  occurrence  of  accidents  such  as external force damage.
