The Application Of Three Levels Of Lightning Arresters In Various Fields

Three levels of 69 kv lightning arrester can deal with surges from different sources respectively: T1 level 9kv 5ka lightning arrester is responsible for protecting against direct lightning strikes. This type of 9kv lightning arrester is often installed at the main distribution point of the building to absorb lightning energy and guide it to the ground wire; T2 level lighting arrester 11kv is responsible for protecting against induced surges. This type of lighting arrester 33kv is usually arranged in the distribution box or sub-distribution cabinet to protect equipment from the transient voltage caused by lightning induction or switching operation; T3 level lightning arrester 20 kv is responsible for protecting against low-energy surges and provides the final precision protection for precision electronic equipment such as computers, control modules, communication devices, etc.
