Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable transformer manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations and high and low voltage complete sets of equipment.The equipment put into production and operation of the project advocates energy saving, intelligence, information and mechanization. The company has established the Henan Triangle Energy-saving Transformer Engineering Technology Research Center,with 71 utility model patents and 15 invention patents.With years of accumulation in the transformer industry and strong technological innovation capabilities, HZEC products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa and other regions, covering more than 40 countries.
Dry-type transformer is a high-performance electrical equipment. It adopts advanced insulation technology, does not require oil immersion, and is safe and environmentally friendly. It is fireproof and explosion-proof, and its operation is stable and reliable. Compared with oil-immersed transformers, dry-type transformers are more adaptable to various environments and have lower maintenance costs. It is widely used in areas where it is particularly suitable for use in locations where fire protection is high, such as mines, oil fields, subways, power plants, schools, hospital, commercial centers, high-rise buildings and all within in the configuration system.
The glass fiber and other insulating materials for winding coils have self-extinguishing characteristics, which will not produce arcs due to short circuits, and the resin will not produce toxic and harmful gases under high heat.
Safety: Fire retardant, no pollution, good corrosion resistance, can be directly installed in the load center.
Moisture-proof: It can operate normally at 100% humidity.
Maintenance-free: It's easy to install, low overall operating cos.
Excellent performance: Low loss, low local discharge, low noise, high mechanical strength, strong short-circuit resistance, strong heat dissipation ability, can run 130% rated load under forced air cooling conditions.
Temperature control guarantee: It's equipped with a perfect temperature protection and control system to provide reliable guarantee for the safe operation of the transformer.
According to the operation report of the products that have been put into operation, the reliability index of the products has reached the international advanced level.

Our company can provide non-standard products according to user requirements.
1. Altitude ≤1000m, ambient temperature: -25ºC--40ºC, indoor type.
2. For air self-cooling and forced air cooling transformers, it is necessary to ensure that the transformer has good ventilation capacity.
3. When the transformer is installed in the basement or other environments with poor ventilation capacity, heat dissipation and ventilation devices must be added.
4. Protection levels are IP00, IP20, IP23 and other types.
5. When the altitude is >1000 meters or the ambient temperature is greater than 40 ° C or less than -25 ° C, the product must be in accordance with the requirements of GB1094.11 Power transformers Part 11: Dry-type transformers to adjust the relevant ratings accordingly.
