Product Description
The KXHXGN Environmental Protection Gas Insulated Ring Main Unit is an innovative power solution utilizing non-toxic, harmless materials. By employing N2 or dry air as its insulation medium, it ensures a safe and sustainable operation, transforming the landscape of eco-conscious design. It significantly reduces gas emissions and facilitates recycling after its life cycle, promoting environmental conservation.
Key Product Features
1 Extensive Application Range
This environmentally friendly GIS cabinet does not utilize any toxic or harmful gases. It is ideal for basements, tunnels, ships, and extreme conditions such as high altitudes, strong sandstorms, or low-temperature climates. The unit is fully insulated and enclosed, allowing it to resume operation even after brief water exposure.
2 Maintenance-Free Innovation
Meticulously sealed high-voltage switch components minimize the need for cleaning and maintenance. Equipped with advanced automation and real-time online detection, it enhances distribution network efficiency while reducing manual labor costs.
3 Unmatched Safety
A robust interlocking system ensures maximum safety with visible three-phase isolation fractures. By eliminating SF6 gas and using explosion-proof vacuum interrupters, it prevents interphase short circuits and explosion risks.
4 User-Friendly Operations
Simplified single-handle operation for disconnector grounding switches eliminates confusion. The solid sealing pole, crafted using the epoxy resin APG process, delivers exceptional mechanical and electrical performance.
Conditions of Use
- Temperature: -25~45ºC, designed for diverse climatic resilience.
- Maximum Daily Temp: Maintained at an upper limit of 35ºC for optimal performance.
- Protection Degree: IP67 for charged body seals; IP4X for the cabinet shell.
- Environment: Pristine surrounding air, free from corrosive or combustible gases and moisture.
- Vibration: Designed for areas devoid of frequent intense vibrations.
