SF6 Gas Isolator

SF6 gas isolators are enclosed in a casting chamber made of epoxy resin and sealed with a sealed pressure system; they are 3-pole and 2-position. The opening and closing operations of the isolator mechanism are performed manually. The closing operation of the grounding isolator is independent of the operator’s movement, as it is carried out by setting the spring, while the opening operation is defined as dependent on the operator’s movement. The operating mechanism monitors the position indicators that reliably indicate the open and closed positions of the contacts. As standard, 2NA+2 NK auxiliary contacts are provided, and additional contacts can be provided upon request.
