Backed by decades of expertise in power distribution, Schneider Electric voltage transformers combine reliability, precision, and innovation. From dry-type to oil-filled models, our solutions deliver consistent performance while helping you step into the future of connected, efficient energy management.
"Our Dry-Type Distribution Transformers offer high levels of reliability and safety. With low flammability, they are ideally suited to critical applications. Best-in-class cast resin transformers are engineered to maximise your investment through reliable performance and a long service life.
- Dry-type distribution transformers are essential components in electrical power distribution, offering an alternative to traditional oil-filled transformers by using air or gas for insulation.
- Filled with environmentally friendly, solid, and resin-based insulation materials, the absence of oil reduces the environmental impact making them safer and less prone to fire hazards and suitable for indoor installations and areas where environmental safety is a concern.
- Low Maintenance: With no oil to manage, dry-type transformers require minimal maintenance, reducing operational costs over time.
- Compact Design: Suitable for limited space installations, such as urban and industrial settings.
Types of Dry-Type Transformers:
- Cast Resin Transformers (CRT): Use epoxy resin to insulate the windings, providing high mechanical strength and moisture resistance.
- Vacuum Pressure Impregnated (VPI) Transformers: Use a vacuum and pressure process to impregnate the windings with resin, offering enhanced insulation and protection against environmental factors.
The digital transformation of MV transformers is helping to provide the operations teams a greater level of collating data-driven information regarding equipment conditions. It allows to take proactive measures, which helps in lowering downtime, promoting the concept of predictive maintenance, as well as keeping maintenance requirements and costs at an all-time low.
Dry-Type Transformers are widely used in:
- Commercial Buildings: For lighting and power distribution in office buildings, malls, and hospitals.
- Industrial Facilities: Powering machinery and processes in factories and plants.
- Data Centres: Providing reliable power with minimal risk of fire.
- Renewable Energy Projects: Supporting solar and wind energy installations where safety and environmental considerations are critical.
