HV / LV Switchgear

High-voltage switchgear (KYN, GGD and more) and low-voltage distribution panels covering generation, transmission and end-use scenarios.

Key Features

1

Full range: KYN28, GGD, GCS, MNS and more

2

Withdrawable and fixed designs for safe maintenance

3

Compartmentalised construction limits fault propagation

4

Smart interfaces available for remote monitoring

HV/LV switchgear is the backbone of any distribution system, performing switching, isolation, control, protection and metering functions. High-voltage switchgear (KYN28A-12, KYN61-40.5, etc.) serves 10 kV and 35 kV systems — the withdrawable circuit-breaker truck can be removed for maintenance, and fully compartmentalised construction contains faults effectively. Low-voltage distribution panels (GGD fixed, GCS/MNS drawout) serve 0.4 kV systems with modular drawer units for easy operation and maintenance.

SAD offers complete switchgear solutions from 0.4 kV to 35 kV. All products comply with GB/T 3906, IEC 62271 and related standards, supported by type test reports and CCC certification. Custom fabrication to design-institute drawings or client specifications is supported, including intelligent circuit breakers, power quality monitoring units (PMU) and remote I/O interfaces (RS-485 / Ethernet / IEC 61850).
