Dry Type Transformers are constructed with epoxy resin insulation that reliably stops arcing and separates electrical currents. Unlike oil-filled versions, the three-phase dry type transformer setup relies on air for cooling. It uses either natural airflow or forced air. This approach provides safer performance and better dependability. The design removes the requirement for upkeep. It also delivers low partial discharge and moisture resistance. These features make it perfect for tough settings. Moreover, the dry type transformer advantages feature explosion-proof qualities. This boosts its safety in vital uses.

Features:

• Peak Efficiency: Notable for its low operational losses, quiet function, and controlled partial discharge. It excels in heat dissipation, allowing it to run at 120% of its rated capacity with forced air cooling.

• Moisture Resilience: Able to perform in extremely humid conditions (up to 100%) and can immediately continue operations after halts, without the need for drying.

• Safety and Eco Compliance: Fire-resistant and devoid of pollutants, making it a safe addition to any load center.

• Temperature Regulation: Incorporates an advanced system for temperature control that secures reliability and safety during operations.

• Installation and Maintenance Ease: Designed for quick installation and is maintenance-free, which significantly reduces operational costs.

• Reliability Assurance: Field performance aligns with top international standards, confirming its reliability.

Our Advantages:

1. High-Performance Windings:

   High-voltage winding: It is vacuum-cast with epoxy resin insulation. Glass fiber mesh adds strength for low partial discharge and strong electrical power. This boosts its ability to handle short circuits.

   Low-voltage winding: It employs a foil build for even ampere turns. An axial cooling air duct helps with better heat removal. DMD epoxy resin cloth provides firm bonding between winding layers.

2. Efficient Core Design: The iron core comes from quality cold-rolled silicon steel sheets. It features a three-stage slanted joint setup. Plus, epoxy resin wrapping lowers no-load loss, no-load current, and core noise.

3. Advanced Cooling System: It includes a low-noise, high-wind-pressure cross-flow top-blowing cooling fan. This raises overload capacity for improved results.

4. Intelligent Temperature Control: A built-in temperature controller boosts operational safety. It also ensures steady, dependable work.

5. Explosion-Proof & Moisture Resistance: The dry type transformer enclosure gives IP33 protection. Materials such as aluminum alloy, cold-rolled steel, or stainless steel provide lasting strength and moisture resistance.
