Dry type transformers are equipped with unique insulating materials that block current flow and inhibit electrical arcing. They differ from traditional units as their iron cores and windings are not soaked in insulating oil. Cooling can occur via natural air or forced air methods. The design offers a safer and more reliable performance, and it doesn't require ongoing maintenance.

Key Features:

1. High Efficiency: Achieves low operational losses, operates quietly, and minimizes partial discharge. Enhanced heat dissipation capabilities enable it to run at 120% of its rated load under forced air cooling.

2. Excellent Humidity Resistance: Functions optimally even in 100% humidity and can restart after shutdown without needing to dry.

3. Compliance with Safety and Environmental Standards: Offers fire resistance and is pollution-free, contributing to safer operations within load centers.

4. Sophisticated Temperature Control: Employs an advanced temperature protection system to maintain reliability and safety during operation.

5. Ease of Maintenance and Installation: Designed for straightforward installation and operates without the need for ongoing maintenance, reducing overall operational costs.

6. Tested Reliability: Field operational studies confirm that the transformer meets the highest international reliability standards.

Our advantages

1. The high-voltage winding is vacuum cast with epoxy resin filled with fillers, with low partial discharge and high electrical strength of the coil. The inner and outer walls of the winding are reinforced with glass fiber mesh plates, which increases the mechanical strength of the coil and improves the ability of the transformer to withstand sudden short circuits.

2. The low-voltage winding adopts a foil structure, which solves the problem of axial spiral angle when using wire winding, making the ampere turn more balanced. At the same time, the coil adopts axial cooling air duct, enhancing the heat dissipation capacity. The DMD epoxy resin pre impregnated cloth is used between the winding layers, and the overall solidification is formed.

3. The iron core is made of high-quality cold rolled silicon steel sheets, with a three-stage fully inclined joint structure. The core column is bound with F-class weft free straps, and the surface is wrapped with epoxy resin to reduce no-load loss, no-load current, and core noise. The clamps and fasteners are with special surface treatment, further improving the appearance quality of the transformer.

4. The transformer is equipped with a cross flow top blowing cooling fan, it is with low noise, high wind pressure, and beautiful appearance, enhancing the overload capacity of the transformer.

5. The transformer is equipped with an intelligent temperature controller, which improves the operational safety and reliability.

6. The casing can provide the further safety protection for the transformer, with the protection levels of IP20, IP23, IP30, IP33, etc. And the casing materials include aluminum alloy, cold rolled steel plate, stainless steel, etc.
