The ZHW13-123 (145) HGIS electrical equipment is a new type of high-voltage power equipment. Based on the advantages of GIS combined electrical apparatus such as compactness, high reliability, and low operation and maintenance workload, it retains the on-site installation and docking busbars of GIS as conventional AIS layout, while cleverly solving the disadvantages of conventional AIS equipment such as large footprint, many connection links, and large maintenance workload. It is suitable for power plants, substations, stations and docks, large industrial and mining enterprises and other 145kV and below power transmission/distribution systems, especially for mountainous substations, urban substations and other projects with tight land use. It can be used for indoor, outdoor or rooftop installation.

Product Advantages

HGIS is a gas insulated metal composite combined electrical apparatus that concentrates circuit breakers, disconnecting/earthing combination switches, current transformers, and voltage transformers in one device.

This characteristic of HGIS equipment determines that, compared with GIS and AIS, it has the following advantages:

High operation reliability and small maintenance workload (basically maintenance-free for 25 years);
Can be directly installed outdoors, with extremely small civil engineering and electrical installation workload, and simple installation;
Small SF₆ gas consumption (only 20% of GIS usage), green and environmentally friendly;

Low full life cycle cost;
Small size and light weight (silicone rubber bushings, aluminum tanks), high pollution resistance, hydrophobicity, and seismic resistance;
Short installation time and few power outages, very suitable for expansion or renovation projects of power plants and substations.
