Lighting Arrester TBP-C
Three phase integrated lighting arrester is a new type lightning arrester which mainly used to protect transformer, switch, bas bar, electrometer, parallel comensating capacitor in 35kV electric system, it also can limit over-voltage of air, vacuum circuit breaker, phase to earth, phase to phase.
Three phase intergrated lightning arrester consists of our lightning arresters by four-stars type, So it can protect each phase to earth and phase to phase from over-voltage, because of its smart stuctures, its function is equals to six lightning arresters, it also solve the problem that lightning arresters can 't protect phase to phase very well.Three phase integrated lightning arrester can be either gap or no series.
