Huawan Dry Type Transformers provide a fire-safe, eco-friendly solution without oil spill risks. Ideal for populated/sensitive areas, they feature recyclable construction and reduced ownership costs through minimal maintenance. Certified to IEC, ANSI & ISO 9001 standards, our ≤35kV units deliver reliable performance in extreme conditions. Advanced engineering ensures superior quality and exceptional longevity.
Primary winding connected to grid AC; high-permeability iron core generates and conducts closed alternating magnetic flux for energy transfer.
Alternating flux induces electromotive force in secondary winding; voltage step-up/step-down is achieved by primary-secondary turn ratio adjustment.
Epoxy-cast/impregnated solid insulation isolates circuits, preventing leakage and short circuits for safe multi-scenario installation.
Two cooling modes: AN (natural convection for stable loads); AF (fan-forced cooling for high loads/short-term overloads).
Two operation modes: continuous operation (rated capacity supply); short-time/periodic load operation (peak loads, loaded-no-load alternation).
No insulating oil medium, no risks of combustion, explosion or oil leakage, and it can be directly installed in high-rise buildings, crowded places and other scenarios.
Adopting epoxy resin casting or impregnated solid insulation structure, it has high thermal class, stable electrical insulation and outstanding short-circuit resistance.
No hidden danger of oil leakage pollution, lower operating noise than oil-immersed transformers, suitable for application scenarios with strict requirements on environmental protection and noise control.
Step down grid-supplied high-voltage electricity (e.g., 10kV, 35kV) to low-voltage power (e.g., 0.4kV) for power distribution systems and terminal equipment, enabling safe power transmission and distribution.
With its oil-free, fire and explosion-proof structure and excellent insulation performance, it is suitable for scenarios like distribution rooms and high-rise buildings, reducing short-circuit and explosion risks and improving the operational reliability of power distribution networks.
Supporting continuous operation and short-term overload operation modes, it can match load fluctuations in scenarios such as commercial buildings and industrial plants, ensuring stable power supply for various electrical equipment.
