Overview:

A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device,

 essentially an air gap between an electric wire and ground, used on electric power transmission and 

telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning. 

The typical lightning arrester has a high-voltage terminal and a ground terminal. When a lightning surge

 (or switching surge, which is very similar) travels along the power line to the arrester, 

the current from the surge is diverted through the arrester, in most cases to earth.

Our advantages:

1. Specalizeding in this industry since 1998.

2. Has lots of experienced engineers,can resolve problems in time

3.Main factory located in the "capital of electronic and electric“ for high/low voltage products ,

can get higher quanltiy material in time.

Thanks for the advantage of it, we can supply higher quality goods with competitive prices.

4.Has sub -factory in African,can ship the goods in time

6.Has built a good sales net in African market---lots of distributors in the market.

7.A little famous in the worldwide.

FAQ:

How does a lightning arrester work?

The typical lightning arrester has a high-voltage terminal and a ground terminal. 

When a lightning surge (or switching surge, which is very similar) travels along the power line to the arrester,

 the current from the surge is diverted through the arrester, in most cases to earth.

Where is lightning arrester placed?

Lightning arresters are generally located on both the high and low side of 

a substation transformer to protect it from strikes coming in either direction.

How much distance does a lightning arrester cover?

The total length of the lightning arrester is 1 meter and the diameter of 25 mm.

 The dimension of the base plate is 9*9 cm. 

This 1kg and 100gm weighted offers a coverage of 45 degrees, that is the surrounded area with a 2-meter radius.

Which device is used as a lightning arrester?

A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device,
