The Solid-Insulated Fully Enclosed Medium-Voltage Switchgear (SXGN-12 series) is a revolutionary 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.
The core functionality lies in its solid insulation technology, which encapsulates vacuum interrupters, conductive connections, disconnectors, and busbars into integrated modules. This encapsulation uses a high-performance composite material (epoxy resin + rubber particles + silicon stone particles), providing excellent electrical insulation, mechanical strength, and resistance to extreme conditions.
Equipped with a three-position disconnector compliant with GB1985-2004 standards, the switchgear ensures no false breaks. The disconnector’s special process structure enhances operational reliability, supporting seamless switching between connection, disconnection, and earthing positions.
All critical components—including circuit breakers, disconnectors, and buses—integrate online monitoring technology. This functionality tracks insulation status, operating temperature, and mechanical performance in real time, providing early warnings for potential issues and enabling proactive maintenance.
The Solid-Insulated Fully Enclosed Medium-Voltage Switchgear features a modular design that allows on-site combination and expansion. It offers two structural options (upper and lower isolation) and multiple cabinet types, enabling customization to meet specific project requirements without extensive rework.
The surface of the main circuit module is equipped with an earthing grid and conductive shielding layer, directly and reliably earthed. This touch-safe design eliminates risks during maintenance or accidental contact, ensuring absolute safety for operators and maintenance personnel.
Fully insulated and enclosed, the switchgear is immune to pollution, corrosive gases, dust, and condensation. Its sealed insulation cabinet can be filled with dry air and pressurized to prevent moisture ingress, making it suitable for high-altitude, coastal, and industrial areas with harsh environmental conditions.
Rejecting SF₆ gas insulation, the solid-insulated switchgear uses eco-friendly materials that produce no greenhouse gases. All components are non-toxic and recyclable, aligning with global environmental regulations and supporting sustainable development initiatives.
With a 375-width design, the product can directly replace traditional SF₆-based equipment, simplifying grid upgrading projects. Its modular structure allows easy on-site expansion, accommodating changes in power demand without replacing the entire system, reducing project costs and downtime.
The solid insulation material and sealed design minimize wear and tear from external factors, significantly extending the product’s service life. It reduces the frequency of equipment replacement, lowering long-term operational costs for power enterprises and improving overall system reliability.
Ideal for smart grid upgrading and transformation, the switchgear supports advanced monitoring and control functions. It integrates seamlessly with intelligent terminal base stations, enabling data-driven management and optimizing power distribution efficiency for urban and rural grids.
Industrial parks with high power demands and complex operating conditions benefit from the switchgear’s robust performance. It provides reliable protection for production lines, transformers, and auxiliary equipment, ensuring uninterrupted power supply for manufacturing and processing activities.
Suitable for high-altitude regions, coastal areas with high salt spray, and cold zones with extreme temperatures, the Solid-Insulated Fully Enclosed Medium-Voltage Switchgear maintains stable operation in harsh conditions. It is also ideal for tunnels, mines, and chemical plants where corrosion and dust are prevalent.
Urban projects such as subways, hospitals, stadiums, and shopping malls require compact, safe, and quiet power distribution equipment. The switchgear’s space-saving design and low noise operation make it suitable for installation in limited spaces, supporting the development of modern urban infrastructure.
The solid insulation uses a composite material blend: epoxy resin + rubber particles + spherical silicon stone particles + strip-shaped silicon stone particles + silica fume, combined with a shielding net. This blend offers excellent insulation, mechanical strength, and resistance to heat, cold, and cracks.
Yes, the Solid-Insulated Fully Enclosed Medium-Voltage Switchgear features a compact design with narrow cabinet widths (down to 375mm for lower isolation type). It is ideal for small installation spaces such as basement utility rooms, tunnel control cabinets, and compact industrial facilities.
