Description


IEK® brand stepped bus insulators are intended for rigid fixing and insulation of current-conducting buses inside the electric panels, busbar bridges and other equipment.

This insulator guarantees the absence of disruptive discharges between the buses and can be used in AC and D electric equipment of 50Hz and voltage under 1000V.

Insulator casing is made of special mechanical impact-resistant non-flammable polymer notable for its high electrical resistance ratings.
