An underground transformer is a compact distribution facility in which the transformer, protective fuses, and other components are housed within a single oil-filled tank.
Overview
An underground transformer is a compact distribution device in which the transformer, protective fuses, and other components are housed within a single oil-filled tank. It is designed for installation in a pit and can meet the requirements of single-ring high-voltage power supply, making it suitable for long-distance, low-load high-voltage distribution systems in applications such as roads, bridges, airports, tunnels, and scenic areas.
Model Meaning
Terms of Use
◆ Altitude not exceeding 1000 m
◆ Ambient air temperature +40℃
◆ Low temperature: -25°C
◆ Average daily temperature +30℃
◆ Average annual temperature: +20°C
◆ Pit operating conditions: Sufficient water immersion to exceed the transformer top cover by 1 meter, with continuous operation possible for up to 120 days.
Note: Depending on customer requirements, ring-network type geographic transformers can be equipped with four-position load switches, while terminal-type transformers can be equipped with two-position load switches.Main Technical Parameters
