10KV 35KV HV Switchgear GTXGN Series SIS Solid Insulated Switchgear Medium

To rank effectively for GTXGN Solid Insulated Switchgear (SIS), the content must emphasize its environmental friendliness (SF6-Free), compact safety, and maintenance-free nature. Engineering firms and utility providers are increasingly moving away from SF6 gas due to environmental regulations, making "Solid Insulation" a high-intent search term.
The following English product page is written with a professional, technical, and authoritative tone to capture B2B procurement and infrastructure project leads.

12kV - 40.5kV Medium Voltage Switchgear | SF6-Free & Eco-Friendly | Compact Modular Design

The GTXGN Series Solid Insulated Switchgear represents the next generation of medium-voltage power distribution. Unlike traditional GIS that relies on SF6 gas for insulation, the GTXGN utilizes solid epoxy resin encapsulation to house all live high-voltage components.
This "Green" switchgear is designed for 10kV to 35kV (up to 40.5kV) systems, offering a completely sealed, fully insulated, and maintenance-free solution. It is the ideal choice for environmentally conscious projects, urban distribution networks, and high-altitude or harsh-climate installations where gas leakage and environmental impact are major concerns.

• 100% SF6-Free (Eco-Friendly): By replacing sulfur hexafluoride gas with solid epoxy insulation, the GTXGN eliminates the risk of greenhouse gas leakage, making it compliant with the strictest global environmental standards and "Net Zero" initiatives.

• Fully Encapsulated & Safety-First: All primary conductive circuits are encapsulated in high-performance epoxy resin. This provides a total shield against dust, humidity, salt spray, and small animals, preventing accidental contact and phase-to-phase short circuits.

• Smart & Modular Architecture: The compact, modular design allows for flexible combinations of "Incoming," "Outgoing," and "Metering" units. It is easily extensible, making it perfect for future grid expansions.

• Maintenance-Free Longevity: With no gas pressure to monitor and no contacts exposed to air, the GTXGN offers a service life exceeding 30 years with minimal operational maintenance.

• Compact Footprint: The solid insulation technology allows for smaller phase-to-phase distances, resulting in a cabinet that is up to 40% smaller than traditional air-insulated switchgear—critical for basement substations and mobile power containers.

1. Smart Urban Grids: High-reliability ring network distribution for densely populated cities.

2. High-Altitude & Low-Temp Zones: Unlike gas-insulated units that lose pressure in extreme cold or high altitudes, solid insulation remains perfectly stable.

3. Coastal & Humid Environments: Ideal for shipyards, tunnels, and tropical regions where salt-air corrosion is a constant threat.

4. Green Energy Infrastructure: Perfect for wind farms, solar PV collector stations, and EV charging hubs seeking "Green" certification.

• Smart Grid Intelligence: Our units are equipped with integrated sensors for temperature, partial discharge, and circuit breaker status, fully compatible with SCADA and remote monitoring protocols.

• Advanced "Five-Proof" Interlock: Features a mandatory mechanical and electrical interlocking system to ensure zero operational errors and maximum staff safety.

• Vacuum Interruption Technology: High-end vacuum interrupters ensure arc-free switching and an exceptionally high mechanical endurance rating.

• Project-Specific Customization: We provide bespoke cabinet layouts and protection relay integrations (ABB, Schneider, or SEL) to match your specific engineering blueprints.

Q: Is Solid Insulated Switchgear (SIS) more expensive than SF6 GIS?

A: While the initial material cost of epoxy encapsulation can be higher, the Total Cost of Ownership (TCO) is lower due to zero gas-refilling costs, zero leakage monitoring requirements, and a significantly longer maintenance-free lifespan.

Q: Does it suffer from "Aging" of the epoxy resin?

A: No. We use high-purity, vacuum-cast epoxy resin with anti-aging additives that maintain dielectric strength for over 30 years under standard operating temperatures.

Q: Can this be used in 40.5kV systems?

A: Yes. The GTXGN series is specifically optimized for both 12kV and 40.5kV applications, providing a standardized look and feel across your entire medium-voltage network.
