Outdoor AC High Voltage Disconnect Switch

This product is a double-column horizontal design with a central opening, capable of being equipped with groundingswitches on one or both sides. The 90" actuated disconnector utilizes a CS17 manual operating mechanism for three-polelinkage operation; the 180*actuated disconnector employs either a CJ6 electric motor operating mechanism or a CS17Gmanual operating mechanism for three-pole linkage operation; the grounding switch uses a CS17G manual operatingmechanism for three-pole linkage operation.
The disconnector is of the double-column V-shaped horizontal opening desian, with each stage composed of a base, postinsulators, outlet sockets, and contacts, lt features two supports and two post insulators mounted at an angle on thebearings at both ends ofthe base, perpendicular to the base. The main electrical components are mounted above the twopillar insulators,rotating approximately 90" along with the insulators.The copper braided strip in the outlet socket is flexibly connected to the conductive rod and the terminal block, whichusers useto connect the circuit.The contact fingers of the middle contact section are assembled in pairs, utilizing self-actuated contact fingers in arotating design to minimize wear between the contacts and fingers during opening and closing, thereby enhancingdurability.
When the disconnector is paired with a grounding switch, the base's fan-shaped and arc-shaped plates ensure that themain electrical circuit cannot be closed while the grounding switch is closed, and vice versa.
