TC(H)GLO transformers are three-phase power dry-type transformers with forced air cooling and cast insulation type “GEAFOL”, thermal class “F” (155 °C), double-winding, general purpose with a capacity from 250 to 2500 kV•A and voltage up to 10 kV. They are designed for converting electrical energy in three-phase alternating current networks with a frequency of 50 Hz. Thanks to their high technical characteristics, reliability, and environmental safety, these transformers are widely used in various industries and national economy sectors.
Design Features
TC(H)GLO transformers have the following design features:
- GEAFOL Cast Insulation: ensures high mechanical strength, resistance to moisture and dust, and excellent thermal stability.
- Forced Air Cooling: allows for efficient heat dissipation generated during transformer operation, ensuring stable operation even under increased loads.
- Siemens Windings: made of high-quality materials, guaranteeing the longevity and reliability of the transformer’s operation.
- Overload Capability: the transformer design allows increasing the nominal capacity by up to 40% without reducing the service life, which is particularly important under variable load conditions.

Advantages of Using TC(H)GLO Transformers
- High Reliability: thanks to the use of quality materials and modern production technologies.
- Environmental Safety: the absence of oil eliminates the risk of environmental pollution.
- Fire Safety: GEAFOL cast insulation does not support combustion, which reduces the risk of fire.
- Compactness: transformers have smaller dimensions and weight compared to oil-filled counterparts.
- Reduced Operating Costs: no need for maintenance of the oil system and regular oil level checks.
Areas of Application
TC(H)GLO transformers are widely used in the following areas:
- Industrial Enterprises: for powering electrical equipment, machine tools, and other electricity consumers.
- Public Buildings: hospitals, schools, shopping centers, where environmental and fire safety are important.
- Residential Complexes: ensuring power supply for multi-story buildings.
- Energy Facilities: substations, power plants, where reliable voltage transformation is required.
- Infrastructure Objects: airports, railway stations, subways.
