EST123-C39 SUB SAC

Cable termination and surge arrester in one

With the IXOSIL EST SUB SA/C, the surge arrester serves as a fixing point for the cable termination at the same time. No additional supporting elements are necessary. The cable connection and surge arrester are installed independently of each other.

  • Quick and esay to install
  • Oil and gas-free - leak-proof
  • Maintance-free
  • 100% electrically individually tested
  • Proven technology
