In eastern Kazakhstan, winter temperatures plunge to -45°C, with an annual temperature variation exceeding 70°C, demanding power grid equipment capable of withstanding extreme cold. Meanwhile, global efforts to curb SF₆ greenhouse gas emissions have created an urgent need for eco-friendly yet reliable alternatives in Central Asia. The XGTD8, featuring nitrogen insulation and a fully sealed design, has emerged as the preferred choice for local grid upgrades.
1. XGTD8 Technical Response: Solving the Dual Challenge of Extreme Cold and Environmental Protection
To address extreme operating conditions, the XGTD8 delivers a proven technical solution with the following core parameters:
Insulation Medium: Nitrogen (N₂) – Liquefaction temperature: -196°C, ensuring a stable gaseous state even at -45°C.
Fully Sealed Welded Tank: IP67 protection rating, effectively sealing out moisture and dust, fundamentally eliminating condensation risks.
Stable Operation Across Wide Temperature Range: Designed for -45°C to +50°C, with an annual leakage rate ≤0.1%, mechanical life of 10,000 operations, and a micro-positive pressure design to maintain pressure stability.
2. More Than Eco-Friendly: Extreme Cold Adaptability with Uncompromised Performance
The XGTD8 eliminates SF₆ while delivering equivalent insulation performance. The combination of nitrogen insulation and a fully sealed design completely resolves challenges related to low-temperature liquefaction and condensation. The equipment has passed IEC and GB/T standard tests and has been successfully deployed in extreme cold regions such as Northern Europe and Northeast China.
