HV Switchgear
KYN28A-12 | KYN28A-24
Indoor metal-clad drawout switchgear for 12 kV and 24 kV utility and industrial networks.
Product Overview
KYN28A-12/24 switchgear is an indoor metal-clad switchgear with a drawout vacuum circuit breaker, designed for 12 kV and 24 kV medium voltage distribution networks. The segregated busbar, breaker and cable compartments improve safety and simplify maintenance. It is suitable for utility substations, industrial plants, rail systems and data centers where reliable MV feeder protection is required.
The switchgear is available with rated currents up to 5000 A and can be configured with different CT/VT, protection relays, metering and busbar arrangements. It is manufactured according to IEC 62271 and GB3906 and supports CQC and CB certification. Every panel is factory assembled, wired and tested before export.
As a medium voltage switchgear manufacturer, Haiyue provides drawings, test reports, export packaging and commissioning support with each order. We also confirm the protection scheme, incoming and outgoing feeder arrangement and local grid standard during technical review.
Before production, our engineers review the project single line diagram, protection scheme, metering requirements, cable entry and local grid standard. After approval, we complete factory assembly, routine testing, export packaging and documentation, and provide commissioning and after-sales support after delivery.
