The Usune Dry Type Transformer is a static transformer suitable for low- and medium-voltage AC power systems. It abandons the traditional oil-cooled structure of oil-immersed transformers, using high-quality epoxy resin, insulating paper, and other solid insulation materials to wrap the core and windings, relying on air or inert gas for heat dissipation.
This product features a compact structure, small size, and light weight, overcoming the installation space limitations of oil-immersed transformers. It eliminates the need for oil storage equipment and dedicated fireproof distribution rooms, achieving an oil-free, pollution-free, and inherently safe operating mode. The equipment possesses excellent moisture-proof, dust-proof, and corrosion-resistant properties, enabling stable operation in complex and harsh environments. It also has strong short-term overload capacity, ensuring a continuous and stable power supply to the power system.
Utilizing integral epoxy resin casting and vacuum pressure impregnation processes, the equipment boasts high mechanical strength and excellent vibration and impact resistance. High-end solid insulation materials provide excellent electrical insulation performance, allowing for stable long-term operation under harsh conditions such as high humidity and dust, exhibiting outstanding weather resistance and stability.
Dry Type Transformers strictly adhere to the IEC 60076 international standard and domestic industry specifications. Through optimized core and winding structure design, they significantly reduce no-load and load losses, resulting in low operating noise, high energy efficiency, and a service life far exceeding that of ordinary transformers, effectively reducing equipment replacement costs.
The oil-free design eliminates the risk of insulating oil leakage, combustion, and explosion at the source. The insulation materials are self-extinguishing and non-flammable, posing an extremely low fire hazard. Suitable for enclosed indoor spaces and densely populated areas, effectively preventing major safety accidents caused by transformer failures.
Eliminating the need for insulating oil filling, there is no risk of soil or environmental chemical pollution. It eliminates the need for oil storage management and waste oil treatment processes, meeting the low-carbon and environmentally friendly requirements of modern urban construction and industrial production, and conforming to global green electricity development standards.
The all-solid-state insulation structure eliminates the need for regular inspection, filtration, and insulation oil replacement required by oil-immersed transformers. Daily maintenance is simple, resulting in low operating costs. The equipment operates stably with a low failure rate, significantly reducing the company's investment in manpower and materials for maintenance.
The equipment has a small footprint and is lightweight, eliminating the need for a dedicated independent power distribution room. It can be flexibly installed in confined spaces such as basement power distribution rooms and electrical shafts, effectively saving on project infrastructure costs and site layout space.
Excellent heat dissipation performance allows it to safely withstand short-term overload operation, easily handling sudden surges in power demand. It is highly adaptable to different temperature and humidity environments, comprehensively covering the power distribution needs of commercial, residential, and industrial scenarios.
High-rise buildings, shopping malls, hotels, office buildings, and other densely populated areas, ensuring indoor power safety.
Hospitals, subway stations, urban transportation hubs, and other public scenarios with extremely high requirements for power supply safety and stability.
Data centers, communication equipment rooms, and other locations requiring high-precision, uninterrupted, and stable power supply.
Indoor production workshops, precision manufacturing plants, and other industrial sites with stringent environmental and safety standards.
A 280-meter high-rise financial center in East China uses Usune 10kV cast-in-place Dry Type Transformers as the core transformer equipment. Addressing the characteristics of high-rise buildings—dense population, complex spaces, and stringent fire safety standards—the product's oil-free, explosion-proof, and self-extinguishing flame-retardant properties fully comply with building fire safety regulations, and its compact structure perfectly fits the limited power distribution space in basements. The equipment has operated continuously for 3 years without failure, exhibiting low noise and low power consumption, providing stable power for building offices, lighting, elevators, and intelligent systems.
A newly built subway line in a coastal city selected Usune 20kV high-performance Dry Type Transformers for power distribution in tunnels and underground stations. The enclosed operating environment of the subway places extremely high demands on the equipment's fire resistance, noise reduction, and weather resistance. This product operates with a noise level ≤55dB, and its inherently safe, oil-free design completely eliminates the risk of fire and explosion in tunnels. It is suitable for the long-term, high-frequency operation of the subway power supply system, and the equipment is currently operating stably throughout the line.
The core difference lies in the cooling and insulation methods. Usune Dry Type Transformers use epoxy resin solid insulation + air cooling structure, eliminating the need for insulating oil and thus preventing oil leakage, fire, and explosion hazards at the source. Compared to oil-immersed transformers, this product has lower noise, lower losses, and is easier to maintain, making it more suitable for indoor and high-safety-level power usage scenarios.
The later-stage maintenance costs of Usune Dry Type Transformers are extremely low. The equipment adopts an oil-free, fully sealed structure, eliminating the need for regular inspections and insulation oil replacements like oil-immersed transformers. Daily maintenance requires only simple dust removal and line inspections. The product boasts stable performance, a low failure rate, and a long service life, effectively reducing the manpower and financial investment required for long-term operation and maintenance.
