Product Description

Product Description

Lightning arrester is another important device often used to prevent lightning damage to communication cables. Suitable for over-voltage protection of transformers, transmission lines, distribution panels, switch cabinets, power metering boxes, vacuum switches, parallel compensation capacitors, rotating electrical machines and semiconductor devices.
 

An electrical appliance used to protect various electrical equipment in the power system from damage caused by lightning overvoltage, operating overvoltage, and power frequency transient overvoltage impact. The main types of arresters include protection gaps, valve-type arresters and zinc oxide arresters. The protection gap is mainly used to limit atmospheric overvoltage, and is generally used to protect power distribution systems, lines and substation incoming line sections.
