The KYN series indoor metal-clad withdrawable switchgear is a new type of center-mounted switchgear developed by extensively incorporating the advantages of similar products both domestically and internationally. The cabinet is equipped with vacuum circuit breakers and is suitable for 6–10 kV power distribution systems in industrial and mining enterprises, high-rise buildings, power plants, and substations, serving as a single-busbar system for receiving and distributing electrical energy.
The KYN61-40.5 type AC metal-enclosed switchgear and control equipment (hereinafter referred to as the switchgear) is an indoor, complete set of power distribution equipment for three-phase AC systems at 50 Hz and a rated voltage of 40.5 kV. It is used in substations and industrial and mining enterprises for the reception and distribution of electrical energy, providing circuit control, protection, and monitoring functions, and is also suitable for applications involving frequent switching operations. This switchgear complies with standards such as GB/T 11022-1999, GB 3906-2006, and DL 404-1997, and incorporates the international standard IEC 62271-2000:2003 as a reference.
The HXGN-type 10 kV modular SF6 ring-main unit is an advanced-generation metal-enclosed switchgear that uses SF6 circuit breakers as the main switching devices. The entire cabinet features air insulation, a compact and simple structure, flexible operation, and easy installation. It is equipped with multiple interlocks and can be configured with electric actuators, potential transformers (PTs), current transformers (CTs), UPS systems, and other components for use in distribution network automation systems. Coupled with modern sensing technologies, advanced protection relays, superior technical performance, and a lightweight, flexible assembly solution, this equipment fully meets the ever-changing demands of the market.
SF6 switchgear is suitable for 10 kV, 50/60 Hz AC distribution systems and is widely used in urban grid construction and renovation projects, as well as in industrial and mining enterprises, high-rise buildings, and public facilities. As a ring-main unit and terminal equipment, it performs functions of power distribution, control, and protection of electrical equipment. It can also be installed in packaged substations, forming a fully sealed system in which all live components and switches are enclosed within a stainless-steel enclosure. The entire switchgear is unaffected by external environmental conditions, thereby ensuring operational reliability and personal safety while achieving maintenance-free operation.
