Know About Raychem RPG’s Transformer Range

OIL FILLED TRANSFORMER

Raychem RPG's Oil Immersed Power Transformers are manufactured in accordance with the most demanding industry and international standards. Transformers can be provided with off-Load and on-load tap changers.

 PRODUCT FEATURES

• Low Loss CRGO Silicon Steel for core
• Oil Filling through Oil Impregnation procedure (Adopted generally for EHV Transformer). It leads to enhanced life
• Mineral oil or Silicon Oil or as per requirement.
• Electrolytic Grade Copper Winding
• Step lap construction and mitred joint for core
• Designed for extreme system supply and ambient temperature
• Losses as per star rating, (if required ) as per BEE
• Low Power Loss and Low Noise Loss

DRY TYPE TRANSFORMER FOR MOTOR DRIVE / CONVERTER DUTY APPLICATIONS

Dry Type Transformer with phase-shifted secondaries provides 18-pulse or better input harmonic cancellation with a power factor above 0.95 under any operating conditions. This eliminates the need for input harmonic filters or power factor compensation, while completely avoiding any common-mode voltages from being imposed on the motor. The quality of the output voltage is so close to perfect sine-wave shape that motors of literally any type old or new, low-speed or high-speed can be operated without any additional stress.

PRODUCT FEATURES

• Transformer with Multiple Secondaries.
• Each Secondary is made of extended Delta to control phase of terminal voltage. 3. Phase shift with secondary are provided with +25°, +15°, +5°, -5°, -15°, -25°
• The other phase shift depending on customer will be provided
• More Efficient

FURNACE TRANSFORMER - ARC / INDUCTION ARC/ SUBMERGED ARC / RECTIFIER DUTY

Furnace Transformers are used in the steel melting and metallurgical industry. They are characterised by high secondary current (for steel up to 90 kA and for ferroalloy up to 160 kA electrode current) and a wide secondary voltage range. The secondary voltage is normally regulated by an on-load tap changer (OLTC) located in the high voltage winding or in an intermediate circuit of a two-cored design within the transformer tank.

PRODUCT FEATURES

• Suitable for large voltage variation on LV side
• LV Voltage variation is ON-Load Type
• Requires 2 Nos. Interconnected Transformer
• Weight is nearly 2 times that of normal Transformer
• Designed to withstand the harmonics generated due to furnace operation
