Forced air cooling (AF) uses fans installed on the transformer body to accelerate the flow of hot air on or inside the equipment. It utilizes forced convection to rapidly dissipate heat from the transformer windings and core, or to force heat exchange between the air and the external environment, thus achieving efficient cooling.
Core Advantages:
Strong Heat Dissipation: Temperature rise reduced by 15-20K, rated capacity increased by 30%+.
Small Size: 20-30% smaller than AN type for the same power, saving engine room space.
High Temperature Resistance: Ambient temperature up to 45℃, suitable for tropical engine rooms.
Intelligent Energy Saving: Fans start and stop according to temperature, saving energy and reducing noise when not fully loaded.
Safe and Reliable: Oil-free design eliminates leakage and fire risks; can operate stably with a 22.5° tilt and a 15° sway.
Application Scenarios (Ships and Offshore Platforms):
Engine Room Main Power Distribution: Power supply for main engine, auxiliary engines, and steering gear (100-1000kVA). Deck equipment: cranes, anchor winches, winches (200–2500 kVA).
Living and lighting: kitchen, air conditioning, lighting (50–200 kVA).
Offshore platforms: drilling, oil production, and wind power platforms (preferred for high-temperature and high-humidity environments).
