It features high fire resistance and flame retardancy, ensuring safe and stable long-term operation in densely populated areas, indoor power rooms, high-rise buildings and flammable and explosive industrial scenarios, with ultra-low operational risk.
2.Eco-Friendly & Pollution-Free
Adopting full dry-type design without any liquid medium, the transformer has no risk of oil leakage, soil or water pollution. The epoxy resin encapsulation material is non-toxic, corrosion-resistant and aging-resistant, producing no harmful substances during operation. It fully complies with international environmental protection standards and green engineering construction requirements, being an ideal green power equipment for sustainable power system construction.
3.Ultra-Low Maintenance & Long Service Life
Thanks to the fully sealed cast resin structure, the internal windings and core are completely isolated from external air, dust and moisture, effectively preventing oxidation, corrosion and insulation aging. There is no need for regular oil detection, oil replacement, cleaning and other complicated maintenance work required by oil-filled transformers. The equipment features stable performance and ultra-long service life, greatly reducing later-stage maintenance labor costs and equipment downtime losses for users.
4.High Energy Efficiency & Cost Saving
Optimized electromagnetic structure design and high-quality raw materials endow the transformer with extremely low no-load loss and load loss, achieving excellent energy-saving performance and high power conversion efficiency. Long-term operation can effectively reduce power consumption and operational electricity costs, bringing stable economic benefits for industrial production and power distribution projects.
5.Wide Application Range & Custom Capacity
This 6KV/10KV three-phase cast resin dry-type transformer is widely applicable to diverse scenarios including urban and rural power grid distribution, power generation supporting projects, industrial manufacturing workshops, commercial buildings, medical institutions, transportation hubs and new energy power systems. To adapt to different project demands, the transformer supports flexible capacity customization, with a coverage range from several KVA to multiple MVA, which can perfectly match the power supply needs of small, medium and large-scale power engineering projects.
Our customers value the 6KV / 10KV Cast Resin Three Phase Dry Type Transformer for its stable performance, safe operation, and reliable quality in long-term power distribution projects. Many users choose this transformer for indoor installations because of its oil-free structure, low maintenance requirements, and strong insulation performance.

A 6KV / 10KV dry type transformer is commonly used in medium-voltage power distribution systems where safety and reliability are priorities. It is suitable for industrial plants, commercial complexes, office buildings, residential communities, power stations, mining facilities, and transportation infrastructure.
In industrial applications, it can supply stable power to motors, control systems, production machinery, and automation equipment. For commercial buildings, it is often installed in electrical rooms to support lighting, elevators, air conditioning, and general power distribution.
Because of its fire-resistant and low-maintenance features, the 3 phase dry type transformer is also widely used in places with high safety requirements, such as hospitals, schools, airports, metro stations, data centers, and public service facilities.
For renewable energy projects, such as solar and wind power systems, dry type transformers can also be used in power conversion and grid connection applications, especially where indoor or containerized installation is required.
The Cast Resin Dry Type Transformer is a preferred solution for many modern power distribution projects because it combines safety, durability, and efficiency. Its epoxy resin insulation helps protect the windings from moisture and contamination, while the dry-type design eliminates the environmental risks associated with transformer oil.
For projects requiring indoor installation, reduced maintenance, and strong fire safety performance, a dry type cast resin transformer is often a practical and cost-effective choice. It is especially suitable for buildings and facilities where reliable electrical performance and safe operation are equally important.
Whether used in industrial production, infrastructure construction, or commercial power systems, the 6KV / 10KV Cast Resin Three Phase Dry Type Transformer provides stable voltage transformation and long service life for medium-voltage applications.

View MoreA dry-type transformer does not use insulating oil for cooling or insulation. A cast resin transformer is one type of dry-type transformer, where the windings are encapsulated with epoxy resin for better protection and insulation performance.
A cast resin dry-type transformer is a transformer with its windings sealed in epoxy resin. It is oil-free, fire-resistant, moisture-resistant, and suitable for indoor power distribution applications.
A cast resin transformer is used to step up or step down voltage in power distribution systems. It is commonly used in factories, buildings, hospitals, data centers, airports, rail systems, and renewable energy projects.
Common transformer types include power transformers, distribution transformers, dry-type transformers, and oil-immersed transformers. They are selected based on voltage level, installation environment, and application requirements.
A dry type transformer is a transformer that uses air or solid insulation instead of insulating oil. It is safer for indoor installation and requires less maintenance than oil-filled transformers.
Cast resin is used to insulate and protect transformer windings. It helps improve moisture resistance, mechanical strength, electrical insulation, and fire safety performance.
