Epoxy Resin Cast Dry-Type Transformers | Fireproof, Maintenance-Free & Energy Efficient

This series of epoxy resin cast dry-type transformers is designed for modern power distribution systems that require high safety, reliability, and environmental performance. Using high-quality thin insulation materials and fully encapsulated coils, these transformers offer excellent flame-retardant, fireproof, and explosion-proof characteristics, making them ideal for indoor installations and load center applications.

With a compact structure and advanced vacuum casting technology, the transformer is completely sealed against moisture, dust, and contaminants. The optimized electromagnetic design ensures low partial discharge, reduced noise levels, and efficient heat dissipation, enabling long-term stable operation even under demanding conditions.

Under forced air cooling conditions, the transformer can operate continuously at up to 140% of its rated load, significantly improving system flexibility and overload capacity. An intelligent temperature controller is integrated to provide real-time monitoring, alarm functions, and centralized control, ensuring safe and efficient operation.

Standards Compliance

This dry-type transformer series is manufactured in strict accordance with international standards to ensure performance, safety, and reliability:

IEC 60076-11: Power transformers – Part 11: Dry-type transformers
IEC 60529: Degrees of protection provided by enclosures (IP Code)

Key Features and Advantages

The dry-type power distribution transformer is engineered for energy efficiency, low operational cost, and long service life. Its low-loss core design helps reduce energy consumption, making it a cost-effective solution for industrial, commercial, and infrastructure projects.

The epoxy resin encapsulated coils provide excellent insulation performance and do not absorb moisture or dust, ensuring stable electrical performance even in humid or polluted environments. High mechanical strength improves resistance to short circuits and external impacts, enhancing overall system reliability.

This transformer is inherently safe, featuring flame-retardant and non-polluting materials, eliminating the risk of oil leakage or environmental contamination. Its maintenance-free design reduces operational costs and simplifies installation, especially in load centers where space and safety are critical.

Optional temperature monitoring and display systems can be configured according to project requirements, providing enhanced protection and operational visibility.

Normal Service Conditions

The transformer is designed to operate reliably under the following standard environmental conditions:

Installation altitude: Not exceeding 1000 meters above sea level
Maximum ambient temperature: +40°C
Maximum daily average temperature: +20°C
Minimum outdoor ambient temperature: -25°C
