Kyn28 Switchgear 20kv

The Usune Kyn28 Switchgear 20kV is an indoor three-phase AC metal-enclosed switchgear, primarily used in 24kV power systems, enabling the reception, distribution, control, protection, and monitoring of electrical energy.

The product uses air insulation + heat-shrinkable/epoxy coating insulation, with an IP4X protection rating (cabinet). Its compact structure and high insulation level make it suitable for various indoor power distribution scenarios. As a medium-voltage power distribution solution manufactured by a professional Chinese manufacturer, this product, with its stable performance and standardized design, has become a trusted high-quality supplier choice for customers worldwide. All core production is completed in our own factory.

Real-world application case

A power distribution station project in an industrial park. A key provincial industrial park includes multiple factory buildings, office buildings, and supporting power facilities, requiring extremely high reliability and safety in power supply. The project selected 16 Usune Kyn28 Switchgear 20kV units, with a rated current of 1250A and a short-circuit breaking current of 31.5kA.

For over two years since commissioning, the equipment has operated stably, quickly clearing short-circuit faults without any safety incidents. The front-mounted maintenance structure significantly reduces maintenance difficulty and downtime, earning high praise from the park's operations and maintenance department.
