Detailed Introduction
- Environmental Parameters of a Stand-Alone Gas-Insulated Voltage Transformer
Ambient Temperature: Conventional products exhibit strong environmental adaptability, with an operating temperature range of -40°C to +40°C.
Altitude: Applicable up to 2,500 m above sea level.
Contamination Level: Suitable for D‑class contaminated environments; the insulator exhibits excellent resistance to pollution flashover, fog, and condensation.
Ice thickness: Can accommodate operating conditions with ice thickness not exceeding 20 mm.
Maximum wind speed: The maximum wind speed it can withstand does not exceed 35 m/s.
Application: Suitable for 110 kV outdoor and indoor open-air (AIS) substations; can be directly mounted on substation structures or supports.
