This 400kVA dry type distribution transformer integrates a fully enclosed IP54-rated cabinet, offering dependable dustproof and moisture-proof power distribution for manufacturing plants, production workshops, and industrial facilities. Designed with a 20kV primary voltage and a 0.38kV secondary, the unit delivers clean, stable low-voltage power without the use of insulating oil. Its cast resin windings and sealed enclosure make it an excellent fit for indoor and sheltered outdoor installations where airborne particles, humidity, or water splashes are constant operational factors.

• Complete IP54 Dust and Moisture Protection: The sealed steel cabinet blocks dust ingress and resists water splashes from any direction, keeping internal components clean and dry in busy manufacturing plants.
• Fire-Safe Dry Type Construction: With zero flammable insulating oil and self-extinguishing cast resin coils, this dry type transformer significantly lowers fire risk, making it ideal for factory floors, data centers, and upgrading aging oil-filled units.
• Energy-Conscious Low-Loss Core: High-permeability grain-oriented silicon steel and multi-step lap joint core construction minimize no-load and load losses, contributing to lower total operating cost over the equipment lifespan.
• Smart Thermal Management Inside a Sealed Cabinet: Engineered air channels, filtered ventilation, and optional forced-air cooling keep temperature rise well within Class F limits, even with the IP54 enclosed design.
• Reduced Noise and Vibration: Precision core stacking, rigid structural supports, and dampening pads result in quiet performance suitable for noise-sensitive areas within a manufacturing plant or data center.

New and Upgraded Manufacturing Plants: Process dust, lubricant mist, and frequent wash-downs expose electrical equipment to early failure. The solution is the IP54 dry type distribution transformer. All live parts are sealed within the cast resin insulation, and the dustproof cabinet prevents fiber buildup and condensation.

Industrial Workshops and Heavy Assembly Lines: Large air quantities moved by overhead cranes stir up fine metallic dust. The design incorporates high-efficiency inlet filters on the IP54 enclosure that trap metallic particles before they reach the windings.

Large Data Centers and IT Facilities: Power reliability, fire safety, and low audible noise are critical. The dry type cast coil transformer eliminates the fire risk of liquid-filled units and meets strict FM Global or local fire codes.

Retrofit and Capacity Expansion Projects: Replacing older oil transformers with this 400kVA dry type unit solves multiple concerns at once. The compact footprint, pre-fitted power terminations, and sealed IP54 construction allow installation in previously unsuitable locations.

It is rated IP54 for indoor and sheltered outdoor locations. The dustproof and moisture-proof enclosure repels splashing water and high humidity, but it is not designed for direct heavy rain or continuous water immersion. For outdoor sites without a canopy, a custom rain hood or higher IP65 cabinet can be provided.

Ventilation within the enclosure follows a carefully calculated cooling path. Filter-protected intake openings at the bottom and hot-air outlets at the top create natural convection without allowing dust inside. The cooling is sufficient for the rated 400kVA under AN (natural air) conditions.

Yes. As a dry type transformer using epoxy resin cast coils, the insulation is self-extinguishing and emits no toxic fumes that would otherwise trigger gas-based fire suppression systems in a data center. It does not contain mineral oil, so the risk of a pool fire or explosion is eliminated.

Maintenance is minimal compared to liquid-filled units. Operators should visually inspect the IP54 cabinet gaskets and ventilation filters every 6 to 12 months, and clean or replace the filter mats depending on dust load in the environment.

Absolutely. These dry type distribution transformers are built to order. High-voltage taps give ±2*2.5% or other standard adjustments; a different low voltage such as 0.4/0.23kV or 0.48kV is common.

Standard factory-assembled units are shipped fully tested with an N2-sealed internal atmosphere. Delivery includes comprehensive dimensional drawings, lifting instructions, and maintenance manuals, enabling straightforward integration into the plant electrical room.
