Metal-oxide 35kV 10KA Polymeric Lightning Arrester
Products Description
The surge arrester is designed to protect the insulation of equipment in 35 kV AC networks against lightning and switching overvoltages.
This is a gapless surge arrester adopting nonlinear metal oxide resistors.
It is engineered to withstand outdoor climatic conditions for UHL1 installation class.
The built-in pressure relief device minimizes the risk of housing rupture during fault operation.
