GTXGN-12 AC Metal Solid Insulation Ring Network Switchgear

The GTXGN-12 AC Metal Solid Insulation Ring Network Switchgear is a medium-voltage distribution unit designed for three-phase AC systems with a rated voltage of 12kV and a frequency of 50Hz. 

Product Advantages
Eco-Friendly Solid Insulation
Uses solid dielectric materials instead of SF₆ gas or other greenhouse gases, aligning with sustainable energy goals.Reduces the risks associated with gas leakage and environmental contamination.

Enhanced Operational Safety
Fully enclosed design isolates live components, reducing the possibility of accidental contact.Integrated interlock systems help prevent incorrect operations, supporting safe maintenance and handling.

Compact and Modular Configuration
Modular structure allows for flexible system expansion and reconfiguration based on specific grid needs.Compact layout supports installation in limited-space environments, including urban substations and industrial units.

Minimal Maintenance Requirements
Solid insulation eliminates the need for gas monitoring or refilling procedures.The enclosed system structure reduces exposure to environmental degradation, contributing to long-term performance stability.

Product Features
Solid Insulation Technology
All high-voltage components are encapsulated in solid insulation, providing high dielectric strength and resistance to partial discharge.Solid-insulated busbars and switches enhance the system's performance in harsh or variable climates.

Metal-Enclosed Structure
The enclosure is built from corrosion-resistant sheet steel, offering protection against dust, moisture, and mechanical impacts.Partitioned internal compartments support independent module operation and fault isolation.

Product Applications
Urban Distribution Networks
Used in city power grids where reliability, space-efficiency, and environmental compliance are priorities.Fits well into underground substations, high-rise buildings, and roadside cabinets.

Industrial Power Systems
Applied in production plants, warehouses, and commercial complexes for power control and distribution.Helps ensure stable energy supply to sensitive equipment and machinery.
