Искровой промежуток Для линейных опорных изоляторов SDI20.2 Ensto

SDI20.2 is used as a arcing protection device for covered conductors. The device is suitable for horizontal, covered conductor, suspension crossarms that are equipped with line post insulators. It can be used in straight lines and also at line angles that are allowed for the crossarms. Nominal plastic covering thickness of the conductor may vary from 2 to 3 mm. Short circuit current: Arc test 2 10 kA, 1 s Short circuit test: I1s = 11.5 kA, 1 s / Idyn = 29 kA
