Product ID: SILICON
Elements are ceramic bonded
blocks of a chemically and electrically stable refractory material. This
material is capable of carrying high surge current with a resulting low
discharge voltage, while offering high impedance to 60Hz power follow current.
The valve block's uniform density results in equal current distribution
throughout each block. The blocks are coated with an insulating surface along
its circumferential length. Each end contact surface is sprayed with a
conductive metallic coating to provide an efficient current interchange point.
Silicon carbide has proved to be an excellent material for the production of
voltage dependent resistors for surge arresters and other voltage protection
Especially, the SIC∮45mm ×10mmH block connected with sparkgap and applied in short duration over voltage protection.
