產品規格

As a professional Gas Insulated Switchgear Manufacturer in China, Liyond provides a comprehensive range of compact and reliable GIS solutions for medium voltage power distribution systems. Our product portfolio fully covers conventional voltage ratings from 12kV to 40.5kV, and we excel in providing customized technical parameters to meet specific project demands. We offer a complete spectrum of gas-insulated technology for diverse global grid requirements.

HXGN-12 Series Ring Main Unit (RMU)

The HXGN-12 series is the ideal choice for 12kV secondary distribution, offering both SF6 gas insulated switchgear and eco-friendly insulation options.

• Environmentally Friendly Option: Includes the HXGN-12/630-20 Air Insulated AC Metal Enclosed Switchgear for projects prioritizing green energy standards.

• SF6 Gas Insulated Design: Features the HXGN-12 SF6 RMU, providing superior insulation and sealing performance in a compact enclosure.

• Compact & Robust: Specifically engineered for urban power grids and industrial facilities where space is at a premium.

Expandable Gas Insulated Switchgear (GIS)

Our medium and high-voltage GIS cabinets are engineered for both primary and secondary distribution, offering heavy-duty performance in a space-saving footprint across our entire 12-40.5kV range.

• Flexible Voltage Adaptation: Our technology platform seamlessly adapts to your specific system voltage, whether it is 12kV, 24kV, 35kV, or 40.5kV.

• Expandable Architecture: These units allow for flexible system scaling, ensuring your infrastructure can grow alongside your power demands.

• Enhanced Stability: Provides the superior insulation strength and breaking capacity necessary for stable operation in large-scale industrial and utility grids.

SF6 Free Combination Inflatable Switchgear

This series provides the ultimate flexibility for customized medium voltage configurations, supporting a modular approach for all standard voltage levels up to 40.5kV.

• Modular Free Combination: Features an inflatable cabinet design that allows for the modular assembly of various functional units based on your unique circuit scheme.

• Eco-Friendly Dry Air Insulation: In addition to standard SF6, we provide advanced solutions of dry air insulated switchgear, offering a sustainable, greenhouse-gas-free alternative without compromising on dielectric strength.

• Hermetically Sealed Protection: All primary switchgear components are sealed in a stainless steel gas tank, making the system immune to humidity, dust, and altitude.

• Maintenance-Free Service: The "sealed-for-life" gas tank technology significantly reduces operational costs and downtime over the equipment's 20+ year lifespan.

Technical Selection Guide

We provide tailored equipment covering the full 12kV to 40.5kV range with customizable parameters. To ensure the correct selection, please provide:

1. Rated Voltage: Specify your required level (e.g., 12kV, 24kV, 35kV, 40.5kV, or other customized ratings).

2. Rated Current and Breaking Capacity: Provide the main busbar rated current and the required fault breaking capability.

3. Insulation Preference: Indicate if you require standard SF6, environmentally friendly air insulation, or specialized protection for harsh environments.

4. Circuit Configuration: Detail the required functional units (e.g., incoming, outgoing, metering, or PT) and whether you require an expandable or non-expandable design.
