Product Overview
Transformer radiators are vital components designed to dissipate heat generated within transformer oil. They maintain the desired operating temperature and enhance the performance and lifespan of the transformer. Our radiators are suitable for both power and distribution transformer, available in standard pressed Steel or customer built designs specifications.
Different Types of Radiators
- Flange to flange type radiator
- Swan Neck radiator (Bend pipe)
- Goose Neck radiator with embaded fins. (Shorter and longer fins)
- off centered radiator (LHS & RHS)
- Hot Dip Galvanized radiator
- Stainless Steel radiator
- Weldable type radiator
- Designed for easy assembly and disassembly.
- Widely used for distribution and power transformers.
- Ideal for transformers requiring frequent maintenance or transport.
- Manufactured from high-quality cold-rolled steel.
- Available with flanges for detachable or welded mounting.
- Suitable for natural oil circulation (ONAN) or forced oil/air circulation (ONAF).
- Permanently fixed type for compact transformers.
- High mechanical strength and oil-tight design.
- Designed to meet specific dimensional and thermal requirements.
- Options for special coatings, materials, and connections.
