The 1000 kVA Three Phase Dry Type Transformer can achieve heat dissipation through natural air cooling or forced air cooling. It does not require insulating oil as the cooling medium and has the advantages of reliability, energy saving, fire prevention, explosion prevention, and simple maintenance. Its core function is to convert high-voltage electrical energy into low-voltage electrical energy, or adjust voltage to meet the needs of different electrical equipment. A 1000 kVA dry-type transformer belongs to medium and large equipment and can support relatively large-scale power distribution needs. In addition to conventional industrial manufacturing and commercial building scenarios, its proportion in photovoltaic new energy applications has also been increasing in recent years.
About dry-type transformers
Dry-type transformers realize voltage conversion through the principle of electromagnetic induction and are mainly composed of an iron core, low-voltage winding, high-voltage winding, insulating materials, and cooling system. CHBEB’s iron core is made of new high-permeability silicon steel sheets stacked together to reduce energy loss; the windings can be customized according to customer requirements and wound with copper or aluminum conductors, then formed into an insulating layer through mature epoxy resin casting technology to improve heat resistance and mechanical strength.
About the cooling method of dry-type transformers
The cooling methods of dry-type transformers are divided into natural air cooling (AN) and forced air cooling (AF). Forced air cooling is more efficient than natural air cooling (forced air cooling requires additional fans), but the cost is also higher. Therefore, in actual applications, the appropriate cooling method should be selected according to specific needs and budget.

Application scenarios and adaptability
Commercial complexes, hospitals, data centers and other places are densely populated places, so they have higher fire prevention and explosion prevention requirements for electrical equipment. Dry-type transformers are the best choice. At the same time, the 1000 kVA capacity can meet the power distribution needs of the above scenarios. Thanks to the design of dry-type transformers, there is no need to regularly check oil levels or replace insulating oil. The maintenance cycle is long, making it suitable for long-term stable operating environments. In addition, the equipment is compact and can be installed in indoor distribution rooms, reducing floor space.
About the dimensions of dry-type transformers
Basic parameters
The common dimensions of a 1000 kVA dry-type transformer are as follows:
| Dimension | Range |
| Length | About 1800–2200 mm |
| Width | About 1200–1500 mm |
| Height | About 2000–2500 mm |
The above dimensions may vary slightly due to factors such as heat dissipation design and winding structure. For models with protective enclosures, the overall dimensions will increase by 150–300 mm.
Installation space planning
A more reasonable installation space is beneficial to the service life of the transformer:
- Heat dissipation channel: reserve at least 800 mm ventilation space on both sides
- Maintenance channel: keep more than 1000 mm operating distance at the front
- Load-bearing requirements: the foundation must be able to withstand 3–5 tons of weight
- Environmental adaptability: in humid environments, it is recommended to increase the bottom elevated height
Other factors
In addition to basic parameters, these details are also important:
- Transportation channel restrictions: confirm door opening and elevator load-bearing dimensions
- Modular design: segmented structure is more suitable for space-limited places
- Future capacity expansion: reserve 10%–15% space margin
- Noise control: large-size heat sinks can reduce operating noise by 3–5 dB

Technical highlights and actual performance
Compared with oil-immersed transformers, dry-type transformers have no oil leakage risk, lower fire hazards, and do not produce harmful gases during operation, meeting environmental protection requirements. The dry-type transformers produced by our company have strong overload capacity and can withstand 120% rated load for a short time, adapting to power load fluctuations. At the same time, our company has optimized the winding structure and cooling air ducts to ensure continuous and stable operation of the equipment at an ambient temperature of 40°C, with strict temperature rise control and extended service life. In addition, customers can equip an intelligent temperature control system to monitor the winding temperature in real time, automatically alarm in case of abnormalities, and improve operational safety.
