HV Switchgear
KYN61-40.5
Indoor metal-clad drawout switchgear for 40.5 kV substation and industrial power systems.
Product Overview
KYN61-40.5 switchgear is an indoor metal-clad switchgear designed for 40.5 kV medium voltage networks. It uses a drawout vacuum circuit breaker and is built with segregated busbar, breaker and cable compartments, which makes operation and maintenance safer than open-frame designs. The switchgear is available from 1250 A to 3150 A and can be configured for utility, industrial, oil and gas, mining and renewable energy projects.
As a medium voltage switchgear manufacturer, Haiyue builds the KYN61-40.5 with CNC-fabricated sheet metal, robotic welding and complete HV testing before shipment. For buyers looking for an indoor switchgear supplier in China, we supply the panel as a complete tested assembly with drawings, test reports, export documentation and commissioning support.
The design focuses on mechanical reliability and maintainability. The breaker can be withdrawn for inspection, the cable compartment provides practical working space, and interlocking prevents incorrect operation. Every KYN61-40.5 order is reviewed, manufactured and tested according to the approved single line diagram.
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.

Applications
Utility substations require reliable switchgear for incoming supply, feeder protection, metering and bus coupling. This product is configured to operate safely under normal and fault conditions, with drawout or fixed units selected according to maintenance requirements.
Industrial plants use this equipment for main incoming supply, transformer feeders and motor circuits. The assembly is designed for continuous industrial duty and can be customized with protection, metering and control options for process reliability.
Oil and gas projects require dependable electrical equipment in demanding site conditions. We can supply enhanced enclosure protection, anti-condensation heating and customized protection schemes for process plant reliability.
Mining sites need robust switchgear for surface and underground power distribution. The design supports safer inspection, maintenance and fault containment in high-demand electrical networks.
Solar and storage projects use this equipment to connect generation and collection systems to the grid. We configure protection, metering and interlocking according to the project grid code and utility requirements.
