GW5-40.5 (72.5) Series Outdoor High-Voltage AC Disconnect Switch

The GW5‑40.5(72.5) series outdoor high‑voltage AC disconnect switches are outdoor high‑voltage electrical apparatus rated for 50 Hz operation, with a nominal voltage of 40.5 kV. They are used to open and close high‑voltage lines under no‑load conditions and to provide electrical isolation for energized high‑voltage circuits associated with maintenance‑required busbars, circuit breakers, and other electrical equipment. They may also be employed to switch small capacitive or inductive currents.

KRC-12 Fully Sealed, Fully Insulated, Gas-Insulated Ring Main Unit

The KRC-12 fully insulated gas-insulated ring main unit is an SF6‑gas‑insulated, metal‑enclosed switchgear. It can be configured from modular units, including load‑switch units, load‑switch–fuse combination units, vacuum circuit breaker units, and busbar incoming units. Incorporating a range of advanced technologies and materials, it delivers outstanding electrical and mechanical performance, exhibits minimal sensitivity to environmental and climatic conditions, features a compact footprint, is easy to install, offers convenient operation, requires no maintenance, and supports flexible configuration options.

ZN63(VS1)-12 Indoor High-Voltage Vacuum Circuit Breaker / Draw-Out Type

The ZN63 (VS1) series indoor hand‑car type high‑voltage vacuum circuit breaker is a three‑phase, 50 Hz, 12 kV indoor switchgear designed for industrial and mining enterprises, power plants, and substations. It provides control and protection for electrical installations and is well suited to applications involving frequent operations. The product features an integrated operating mechanism and main body, allowing it to function as a fixed unit or to be combined with a push‑in mechanism to form a hand‑car assembly. The main circuit can be equipped with an integral solid‑enclosed pole, enabling compact design, high reliability, and maintenance‑free operation. It is compatible with KYN28A12 center‑mounted cabinets and XGN series fixed‑type switchgear.
