The disconnector adopts a double-column horizontal telescopic structure, consisting of base frame, insulator columns, conductive blade assembly, and operating mechanism. The telescopic contact system forms a reliable insulating break when opened, providing a clearly visible air gap for safe maintenance isolation.
The SRCJ2 motor actuator provides single-pole operation with three-pole linkage capability. The earthing switch can be installed on one or both sides and is available with manual or motor operation.
- Robust telescopic structure：Double-column horizontal telescopic design provides a clearly visible isolating gap when open, with reliable plug-type contacts ensuring positive engagement
- EHV-grade insulation performance：Designed for 550 kV class insulation coordination, with power-frequency, lightning impulse, and switching impulse withstand levels meeting stringent EHV substation requirements
- Reliable earthing switch ：the earthing switch with two-step opening and closing motion ensures reliable contact under heavy short-circuit conditions; available on one or both sides
- Flexible operation：Motor actuator supports single-pole operation with three-pole linkage capability, enabling both independent phase control and synchronized three-phase switching
- High mechanical endurance：Robust mechanical design rated for extended operating cycles, suitable for frequent switching in transmission substations
- Large creepage distance options ：Standard and heavy-duty creepage distances available for clean and polluted environments
- Low radio interference：Optimized contact design and smooth surface profiles control corona discharge, maintaining low radio interference voltage levels
- IEC 62271-102 compliant ：Fully type-tested in accordance with IEC 62271-102 for disconnectors and earthing switches
