Product Parameter

Operating Environment

The operating environment of the 11KV Input 0.4KV Output Three phase Oil Immersed Transformer must meet core conditions such as temperature, humidity, and altitude to ensure insulation performance and heat dissipation efficiency.

Core Environmental Requirements

Ambient Temperature: The normal operating temperature range is -25℃ to 40℃. The maximum ambient temperature shall not exceed 45℃, and the minimum shall not be lower than -40℃ (customization is required for special low-temperature scenarios).

Relative Humidity: The ambient relative humidity shall be ≤95% (at 25℃). Avoid condensation-induced insulation dampness.

Altitude: The default applicable altitude is ≤1000 meters. For altitudes exceeding this limit, enhanced insulation design or increased heat dissipation capacity is required.

Installation Site: Suitable for both indoor and outdoor installation. Outdoor installations require rainproof and sunshade facilities. Keep away from flammable, explosive, corrosive gases and dust sources.

Other Conditions: No severe vibration (vibration acceleration ≤0.1g). Adequate ventilation shall be maintained to ensure unobstructed heat dissipation channels.
