Product Overview
  • Outdoor Environment Tolerance: Relying on an efficient oil-cooled heat dissipation system and combined with a customized protective shell (made of galvanized steel plate + fluorocarbon coating, with weather resistance grade reaching C4), it can be directly installed in outdoor open-air sites without the need to build a power distribution room, saving 40%-50% of the single-project site construction cost. Even under high-temperature conditions in summer (above 40℃) or short-term high-load (120% rated load for 1 hour) working conditions, it can still maintain stable operation, avoiding equipment shutdown due to overheating.
  • Strong Load Adaptability: The thermal buffering capacity of mineral oil enables it to cope with load fluctuations common in basic power distribution scenarios (such as load changes during the rural irrigation season and the peak production season of suburban factories). No frequent adjustment of operating parameters is required, ensuring the continuity of power supply.
