2023 Pinggao DFLT-145P (ZHW1‑145) 145kV 2000A hybrid switching module

The Pinggao ZHW1‑145 hybrid switching module is a high-voltage substation component used for controlling and protecting electrical power systems at 145 kV. It’s commonly deployed in outdoor substations, especially where space, installation time, or maintenance access is limited.

This is a complete unit that was going to be installed in a utility project that was cancelled, so it is a turn-key ready module. It includes everything including some spares. 

Packing list is available on request.

Combines the benefits of both:

• GIS (compact, sealed, low maintenance)
• AIS (air-insulated, more flexible, lower cost)

Integrates multiple switching and protection functions into a single modular unit:

• Circuit breaker
• Disconnector
• Earthing switch
• Current and voltage transformers

Usage examples:

1. 145 kV substations in:

• Transmission and distribution networks
• Industrial facilities (e.g. mining, steel plants)
• Renewable energy sites (e.g. wind/solar farms)
• Rail electrification systems (e.g. 25 kV traction substations)

1. Substation retrofits and upgrades:

• Ideal when replacing old AIS components without requiring major civil works
• Can connect to either AIS busbars or GIS switchgear

1. Space-constrained installations:

• Urban areas
• Mountainous terrain
• Mobile substations
