KYN28 Metal-Clad Withdrawable Switchgear

KYN28 metal-clad switchgear is one of the most widely used medium-voltage switchgear solutions worldwide. It is extensively applied in power plants, substations, industrial facilities, and commercial complexes.

The switchgear adopts a fully metal-enclosed design that separates the busbar compartment, circuit breaker compartment, cable compartment, and relay/instrument compartment. This compartmentalization significantly enhances operational safety and fault containment capability.

KYN28 switchgear is equipped with a withdrawable vacuum circuit breaker truck, enabling convenient maintenance and improved service efficiency. Its comprehensive interlocking system effectively prevents operational errors and enhances personnel safety.

XGN Fixed Metal-Enclosed Switchgear

The XGN series fixed switchgear features a compact design and can be configured with SF6 load break switches, vacuum circuit breakers, or environmentally friendly solid-insulated technologies. It is widely used in ring main units, compact substations, and renewable energy projects.

Compared with conventional metal-clad switchgear, XGN switchgear requires less installation space and offers lower investment costs, making it particularly suitable for urban distribution networks and space-constrained applications.

For environmentally conscious markets, especially in Europe, we also provide Clean Air and solid-insulated solutions that eliminate SF6 gas and comply with the latest F-Gas regulations.

GIS Gas Insulated Switchgear

GIS (Gas Insulated Switchgear) is an essential solution for modern urban power grids and large infrastructure projects. GIS integrates circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, and busbars into a fully enclosed gas-insulated compartment.

Compared with conventional AIS (Air Insulated Switchgear), GIS can reduce installation space by more than 70%, significantly lowering maintenance requirements while improving operational reliability.

GIS is particularly suitable for underground substations, rail transit systems, high-rise buildings, offshore platforms, and urban locations where land availability is limited.

Advantages of IEC and ANSI Dual Certification

For international projects, compliance with local standards is one of the most important factors in equipment procurement.

IEC standards are widely adopted across Europe, Asia, the Middle East, Africa, and Australia, while ANSI/IEEE standards are primarily used in the United States, Canada, and parts of Latin America.

Our products are tested and certified according to IEC 62271 and ANSI C37 standards. We can provide dual-standard designs to help customers meet local utility requirements, simplify project approval, and reduce procurement risks.

Main Applications

Utility substations and power transmission projects.

Solar power plants and wind farm substations.

Oil, gas, and petrochemical facilities.

Railway, metro, and transit systems.

Data centers and cloud computing infrastructure.

Steel mills, cement plants, and mining operations.

Airports, ports, and large commercial complexes.

International EPC and turnkey projects.

How to Select the Right High Voltage Switchgear?

If your project has sufficient installation space and requires flexible feeder expansion, KYN28 metal-clad switchgear is often the preferred solution.

If project budget is a primary concern and fast deployment is required, XGN fixed switchgear provides a cost-effective option.

For locations with extremely limited space or harsh environmental conditions, GIS gas insulated switchgear delivers superior reliability and a longer service life.

Frequently Asked Questions (FAQ)

What is the difference between KYN28 and GIS switchgear?

KYN28 uses air insulation and offers lower investment costs with convenient maintenance, while GIS utilizes gas insulation, providing a much smaller footprint and higher operational reliability.

What voltage ratings are available for high voltage switchgear?

Common voltage levels include 3.6kV, 7.2kV, 12kV, 24kV, 36kV, and 40.5kV.

Do your products support smart substation applications?

Yes. Our switchgear can be equipped with IEC 61850 communication systems, online monitoring devices, and intelligent protection relays for digital substation integration.

Can you provide both IEC and ANSI compliant products?

Yes. We can customize switchgear according to the standards and utility requirements of the target market.
