Outdoor High voltage disconnect switch 126kV

The disconnector consists of three single-pole units and an operating mechanism. Each pole comprises a galvanized steel base, rotating post insulators mounted at both ends, and a conductive assembly with self-lubricating rotating contacts. The V-type opening motion ensures a compact footprint while maintaining adequate phase-to-phase and phase-to-earth clearances.

The RDS-126 is widely used in 110 kV and 132 kV class substations for busbar and feeder isolation, line disconnection, and bus-transfer current switching. It is well-suited for distribution substations, industrial power parks, wind farm collection stations, and utility primary substations.

A  earthing switch can be installed on one or both sides, available with manual or motor operation. The disconnector supports both single-pole and three-pole linkage operation.

Technical Parameters

• 110 kV / 132 kV primary substations ：Busbar and feeder isolation in utility distribution and sub-transmission networks
• Wind farm collector stations：Isolation of wind turbine feeders at the collection substation before step-up to the transmission grid; compact V-type design fits constrained turbine substation layouts
• Industrial power distribution ：Isolation for large industrial loads such as steel mills, mining operations, and petrochemical plants connected at 110 kV or 132 kV
• Substation brownfield refurbishment:Direct replacement for existing center-break disconnectors without modifying foundation layout, reducing outage time
• Rural electrification substations:Cost-effective disconnector solution for remote substations where reliable isolation and low maintenance are priorities
