Product ID: SILICON


Silicon Carbide Element

      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 devices.

Features:
  • Elements are available for normal duty distribution class arresters and design has been tested in accordance with ANSI / IEEE C62.1.
  • High reliability and excellent durability. More than 1,000,000 units have been manufactured.
  • Glazing of side treatment (nonflammable).
