PRODUCT OVERVIEW
SG (H) series dry-type transformer is a high-performance transformer where the core and winding are not immersed in insulating oil.
It is available in two structural types: Solid insulation encapsulated winding and non-encapsulated winding.
It is ideal for fire-proof and explosion-proof environments.
PERFORMANCE CHARACTERISTICS
No oil, zero pollution, flame retardant, and self-extinguishing for superior fire prevention.
Low loss, high efficiency, and ultra-low noise operation.
Small local discharge (under 30 PC) with a reliable long-term service life of up to 30 years.
Excellent resistance to cracks, temperature fluctuations, and sudden short-circuits.
Superior moisture-proof properties; capable of running under 100% humidity without prior drying.
Cost-effective installation: No separate transformer room, oil collecting pits, or heavy load-bearing beams required.
TECHNICAL PARAMETERS
Rated Capacity: 100-2500kVA
Rated Voltage: Primary 10kV/6kV; Secondary 0.4kV (Customizable)
Frequency: 50Hz / Phase: Three-phase
Cooling Method: AN/AF
Insulation Grade: Grade H
APPLICATION AREAS
Suitable for environments with high fire protection requirements, large load fluctuations, or humid conditions including:
Airports, Power Plants, Metallurgy, Hospitals, High-rise Buildings, Shopping Malls, Petrochemical Industry, and Nuclear Power Stations.
