  • CSA Certified

• Rated Power: 100 KVA to 30,000 KVA
• Voltage Class up to 72 kV
• HV Winding: Vacuum Cast In Mould
• LV Winding: Vacuum Cast / Pressure Cast
• Designed for extreme ambient conditions

• Distribution Transformers
• Power Transformers
• Earthing Transformers
• Marine & Offshore Transformers
• Isolation Transformers
• Rectifiers

Compact Design
• More compact size
• Require less space than oil cooled units

Low Maintenance
• Only need air to cool
• Liquid testing becomes obsolete
• Smooth coil surface eliminates heavy dirt build-up
• Routine visual inspection is required

Echo Friendly & Safe
• Zero risk for oil leaks and pollution
• Self extinguishable Non-toxic substances utilized
• Suitable for heavy condensation
• Withstand abrupt environmental changes from -25ºC to +40ºC
• Obtained C2/E2/F1 tests according to IEC 60076-11

Low Noise Level
• Due to design flux densities and flexible winding supports, the noise levels during operation are reduced by a considerable amount.

Zero Oil Usage
• Only needs air to cool
• No extra costs for liquid-level checking
• No oil testing
• No oil recycling costs
• No dielectric testing for moisture absorption

Moisture Resistant
• The complete embedding of the transformer winding in resin prevents the penetration of moisture.

Low Installation Cost
• No restrictions on the installation site
• No ground water protection costs
• Service life expectancy of 20+ years
• Low failure rate when operated within designed parameters

Crack Resistant
• Due to historical cracking of cast resin transformers, the latest technology has introduced glass fiber reinforcement in the windings that eliminates cracking due to its heating and cooling curves.

Self Extinguishing
• Insulation of Epoxy resin and Quartz powder
• Winding is flame-retardant
• No need for costly fire extinguishing equipment
• No toxic gases are produced
