High Voltage GIS TGP145 is a compact, metal-encapsulated switchgear designed for high reliability and space-constrained applications. Featuring self-arc-extinguishing circuit breaker technology, it ensures excellent breaking capacity, short arc time, and a long service life, with total breaking time within 3 wave cycles and up to 22 full-capacity break operations. Compliant with IEC 62271-203 and KEMA-certified components, this GIS switchgear is ideal for utility, oil & gas, industrial plants, hydropower stations, and offshore platforms. Its modular design supports flexible configurations such as single-bus, bus-tie, and double-bus, enabling seamless integration and future expansion. Constructed with high-precision aluminum casting alloy, it offers lightweight structure, low eddy current loss, and excellent corrosion resistance. The TGP145 is engineered to deliver stable and efficient performance in critical power infrastructure projects.More
The circuit breaker adopts self-arc-extinguishing technology with excellent performance of breaking capacity, short arc time, and long service life. Total breaking time is within 3 wave cycles and 22 times of full capacity breaking are possible.
Modular Design
The modular design facilitates the layout as well as future expansion and reconstruction. Catering to customers' requirements, the configuration mode includes sectionalized single-bus, Bus-tie, or double-bus.
High-Precision Aluminum Casting Alloy Material
Aluminum alloy enclosure brings about the lightweight and poses less foundation load. Corrosion-resistance performance is high and the eddy loss is low.
