Epoxy Resin Cast Dry-Type Distribution Transformer | Safe, Maintenance-Free & High Efficiency

The epoxy resin cast dry-type distribution transformer is a reliable and energy-efficient solution designed for modern power distribution systems. With advanced casting technology and high-quality insulation materials, it ensures excellent safety performance, environmental protection, and long-term operational stability. Its flame-retardant and pollution-free design allows direct installation in load centers, making it ideal for industrial, commercial, and infrastructure applications.

This transformer features a maintenance-free structure, easy installation, and low overall operating costs. Its superior moisture resistance enables stable operation even in environments with up to 100% humidity, ensuring consistent performance in harsh and demanding conditions.

With optimized electromagnetic design, the transformer delivers low loss, low partial discharge, and low noise performance. It also offers strong heat dissipation capability and can operate safely at up to 150% of rated load under forced air cooling conditions, providing flexibility for variable load demands.

An advanced temperature protection and control system is integrated to ensure safe operation. Equipped with a BWDK series signal thermometer, the temperature sensor is embedded within the low-voltage coil to monitor real-time operating temperature. The system supports automatic temperature detection, display, over-temperature alarm, and trip functions, enhancing operational safety and reliability.

The low-voltage winding is manufactured using high-quality copper or aluminum foil with Class F insulation. Produced on specialized foil winding machines, this design effectively improves short-circuit resistance, reduces ampere-turn imbalance, enhances heat dissipation, and ensures consistent product quality. The winding ends are sealed with resin for moisture-proof and anti-contamination protection, while copper conductors are welded using advanced argon arc welding technology for superior conductivity and durability.
