IEK YIS11-4-30-B is a step, power, with a bolt

IEK stepped insulators are designed for hard fastening and insulation of conductive tires inside electric shields, tire bridges and other equipment.

insulators can be used in electrical equipment of DC and AC with a frequency of 50 Hz and voltage up to 1000 V, and guarantee the absence of breakdowns between the tires.

the insulator case is made of a special, resistant to mechanical exposure, a non -combustible polymer with high electrical resistance.
