1.The disconnector consists of a base, an insulating pillar, a conductive part, and an operating mechanism. There are two pillars at each pole, and the upper end of each pillar is equipped with a conductive knife, and the contact of the knife on both sides is in the middle of the two pilars. The lower ends of the pillars are each equipped with bearing sleeves. Driven by the operating mechanism, the knife can be rotated horizontally by 90° to meet the requirements of opening and closing.
2.The disconnector is a unipolar type, and the three poles can also be connected into a three-pole type that can be linked by a connecting rod. Equipped with CS11 type or CS8-6D type manual mechanism operation. Among them, CS17 is used for disconnector with double grounding devices. (The motor mechanism can be equipped as needed).
3.The disconnector has a reasonable structure and flexible operation; it can be used as a single pole or as a three-pole, and it is easy to install; the opening distance of the contact knife is large, and the insulation is safe and reliable. It can also be ungrounded or equipped with single-sided grounding or double grounding according to user needs.
