Sealed Solid-Insulated Medium-Voltage Switchgear | SXGN-12

Overview

The solid-insulated fully enclosed medium-voltage switchgear (SXGN-12 series) is a power distribution solution that redefines reliability and sustainability in medium-voltage systems. As a solid-insulated switchgear, it uses advanced solid insulating materials to encapsulate key conductive components, achieving full insulation and full enclosure.

Designed for 12kV power grids, this product caters to power grid upgrading, industrial transformation, and urban infrastructure projects, offering versatile solutions for circuit protection, load control, and power supply. Its modular design and environmental friendliness make it a cornerstone of modern smart grid development, ensuring safe, efficient, and long-lasting power distribution.

Key Features

• Solid insulation — advanced solid insulating materials encapsulate the key conductive components, achieving full insulation and full enclosure.
• Composite insulation material — the solid insulation uses a composite blend of epoxy resin, rubber particles, spherical silicon stone particles, strip-shaped silicon stone particles and silica fume, combined with a shielding net.
• Insulation, mechanical strength and crack resistance — the blend offers excellent insulation and mechanical strength together with resistance to heat, cold and cracks.
• Compact design — narrow cabinet widths, down to 375mm for the lower isolation type, suit small installation spaces.
• Modular design — modular construction supports flexible configuration of circuit protection, load control and power supply.
• Advanced monitoring and control — supports advanced monitoring and control functions, integrating seamlessly with intelligent terminal base stations for data-driven management.
• Environmental friendliness — a solid-insulated, fully enclosed design without reliance on insulating gas.
• Low noise operation — quiet operation suits urban installations such as subways, hospitals, stadiums and shopping malls.

Technical Specifications

Applications

• Power grid upgrading projects — ideal for smart grid upgrading and transformation, supporting advanced monitoring and control functions and integrating with intelligent terminal base stations.
• Industrial park power transformation — provides reliable protection for production lines, transformers and auxiliary equipment in industrial parks with high power demands and complex operating conditions.
• Special environment power distribution — suitable for high-altitude regions, coastal areas with high salt spray, and cold zones with extreme temperatures, and ideal for tunnels, mines and chemical plants where corrosion and dust are prevalent.
• Urban infrastructure construction — compact, safe and quiet operation suits subways, hospitals, stadiums and shopping malls, where space is limited.

Installation Conditions

• The compact design with cabinet widths down to 375mm suits small installation spaces such as basement utility rooms, tunnel control cabinets and compact industrial facilities.
• The switchgear maintains stable operation in high-altitude regions, coastal areas with high salt spray, and cold zones with extreme temperatures.
• It is suitable for tunnels, mines and chemical plants where corrosion and dust are prevalent.
• Where advanced monitoring is required, allow for integration with intelligent terminal base stations and associated data connections.

How to Select

• The circuit protection, load control and power supply functions required.
• The available cabinet width — the lower isolation type is 375mm wide.
• The environmental conditions at the site, including altitude, salt spray, extreme temperatures, corrosion and dust.
• Whether advanced monitoring and control functions and intelligent terminal base station integration are needed.
• The installation space constraints, particularly for basement utility rooms, tunnel control cabinets and compact industrial facilities.
