Introduction
Isolation Handcart is a popular selection of vacuum circuit breaker parts. Our TAG2 indoor assembly poles type isolation handcart is the latest domestic achievement. It is suitable for Air-insulated Switchgear (Ampower-KYN28A, ABB-Unigear, Siemens-Nxair, Schneider-Nvnex and so on) and able to be interchanged with similar products. And it is available in many varieties, excellent in performance, and widely applicable to:
1. Energy and infrastructure: power plants, 220KV/110KV substations, primary and secondary distribution systems.
2. Industrial production: power supply systems for pulp and paper, construction materials (glass, cement, ceramics), steel and metal products, aluminum, petrochemical and other industrial productions.
3. Building: power supply system of large, medium-sized buildings and residential areas.
4. Other: petrochemical, transportation, and mining areas.
