Description:
lightning arrestor zinc oxide arrester
1.Housing resistant rough handling
2.Low residual voltage
3.High energy input cap
Polymeric Lightning Arrester Nominal Discharge Current 5kA
Application:
Massive productions of lightning arrester (MOA),either with porcelain or polymeric housing, are suitable in thesystems of power generation, power transmission, powertransformation, and power distribution under AC 220kV and below.They are mainly used to keep the amplitude of lighting impulsewithstand voltage and switching impulse withstand voltage to theprescribed level.
