Rectifier Duty Transformers Dealers

Rectifier duty transformers introduced not just only for transmission for electricity to entire networks but also for other purposes. These transformers used to withstand against entire harmonics occurred by converter of rectifier. While electric power supply rectifier duty transformers also used for earthed screen between two windings to decrease disturbance of radio frequency.

• capacity range: 10 KA DC
• voltage: 33 KV.

Rectifying transformers are suitable for 6 or 12 pulse operation with options of different winding connections on primary & secondary windings with or without inter phase transformer. The capacity ranges up to 10 KA DC with primary voltage up to 33 KV. It is used in metallurgic and chemical procedures, Rectifier transformers (also called furnace transformers) are used for their power to support the current in an extreme short-circuit. The rectifier circuit used in most electronic power supplies is the single-phase bridge rectifier with capacitive filtering, usually followed by a linear voltage regulator.

We manufacture quality Rectifier Duty transformers up to 6300 KVA capacity in Oil cooled type having various voltage and current ratings as per the relevant IS standard.Besides all standard fittings as specified in IS standard, optional fittings such as lowhigh frequency, short circuit and overload protections cutoffs can be provided as per customer’s requirement.

In view of the requirement of Indian Industry, we have introduced VOLTAMP Cast Resin (Dry Type) Transformers. This introduction will supplement our existing product viz. Vacuum Resin Impregnated Dry Type Transformers. Dry Type Transformers of both the above varieties are in use in the Indian Industry. To offer time proven designs substantiated by reliable field experience we have entered into Technical Collaboration with Ms. HTT, Hann Munden, Germany.They manufacture Cast resin Power and Distribution Transformers, Converter Transformers, Transformers with On Load Tap Changers (OLTC), Motor - starting Transformers, Testing Transformers, etc. Their specialty is to make special transformers to meet customers' requirements.

Raychem RPG offers various types of Furnace transformers like Arc furnace, Induction arc, Submerged arc, Rectifier duty & Ladle furnace transformers. These transformers are rigidly designed to withstand repeated short – circuit conditions and high thermal stress and to be protected from operational voltages resulting from the arc process. The furnace transformer supplying power to furnace has to handle extremely high value currents in the order of kAmps depending upon furnace ratings.

We manufacture Cast-Resin Dry Type Transformers upto 3000 KVA; 33KV class as per Indian & International Standards i.e. IS, IEC & ANSI etc. Our transformers are design to withstand high humidity, temperature, adverse service conditions & short circuit levels & all these make our products an ideal choice. Designing, selection of raw materials, state of the art – Casting Plant, in house testing facility & highly experienced manpower make our products very reliable & cost competitive. Maintenance FreeDue to encapsulation of coils with cast resin the coils dimensions are stable & no coil tightening is required to maintain the short circuit strength. Also no check of oil level and electrical insulation/oil is required. Non- HygroscopicIn cast-resin dry-type transformers, the complete encapsulation of primary and secondary winding in epoxy resin prevents penetration of moisture into windings. The cast resin offers very good protection against adverse ambient conditions. These transformers can work without disruption of service at 100% humidity. Non Inflammable and Self ExtinguishingDue to high quality insulation material the transformer is practically non-inflammable by an electrical arc, special fire protection measures are not required. Resistant against Temperature FluctuationThe insulation material used is glass fibre reinforced with epoxy resin of class 'F' which can withstand wide temperature variation. Higher Impulse StrengthContrary to the conventional dry type transformers the cast coil transformers are better in respect of impulse voltage withstand strength. Higher Short Circuit StrengthHigher dynamic short circuit withstand strength as compared to oil immersed and conventional dry type transformers because of fibre glass reinforced epoxy encapsulation. Free of Partial DischargesNo partial discharges can occur during operation. Instant SwitchingDue to the high grade insulation material, coils are non hygroscopes & the transformer can be switched on directly without pre-drying even after a long period of service interruption. No Leakage or Pilferage of OilAs cast resin transformers are solidly cast, problem associated with oil filled transformers like oil leakage and pilferage of oil is completely avoided. Saving in SpaceThese transformers are generally smaller in dimensions and lesser in weights. The construction and installation cost for the sub-station can be reduced by adopting dry type transformers. Eco-FriendlySince no oil is used in these transformers, there are no chances of contamination of ground water due to oil leakage. Saving in Civil work cost and LT cablesWithout fire or danger of explosion, it is possible to place the transformers near to the load centre. Also, these transformers do not need construction of special fibre brick walls or oil pits, which reduces the overall civil works. Additionally, since LT cables are not required, thers is also saving in cost on account of expensive cable laying works.     Public Places and High rise buildings Shopping Malls Railway Fixed traction installation Underground Cranes Seaports and Offshore platforms Drives Gas ,Turbines , Generators and Drilling system Solar Application Mining Ranging up to 3000 KVA Capacity Up to 33 KV Class Three-Phase, 50 / 60 Hz Single / Dual Ratio Naturally Cooled (AN) or Forced Air Cooled (ANAF) Sheet metal enclosure with vents for air circulation IP-23 or as per customer's requirement Accessories / Fittings as desired by customer Insulation Class F / H, others on request Applicable Standards IS:11171, IEC:60726 Tap Changer: Tap Links / On Load Tap Changer (OLTC) with RTCC & AVR Temperature Sensors for alarm and trip protections        

CG offers converter transformers, which operate at the fundamental frequency of an alternating system. These are designed for one or more output windings connected to the rectifier loads. We offer Induction Thyristor duty transformers suitable for 3 Pulse 6 Pulse 12 Pulse 18 Pulse drive configurations. It is possible to make major changes in the output current and voltage by using a transformer with a different rectifier configuration. Extra care is taken in design and manufacture of Induction Thyristor transformers due to the harmonics that are likely to appear in the transformer windings. These harmonics are likely to increase the stray losses in the transformer.

We are offering rectifier duty transformers. Which is suitable for diode and thyristor rectifiers to be used for electrolysis processes.

Linear Voltage Regulating Transformer has been designed to meet a wide range of heavy-duty industrial application as well for Electricity Supply Utilities. Globally, these have become an established method of control, wherever continuously variable on-load control of voltage and power is needed. These can also be used to control many industrial processes like adjusting temperature, flow speeds, drive speeds, etc. to a pre-set programme.Voltage Regulating Transformers & Regulating units combine fixed ratio transformers with regulating transformers to extend their rating, connection, designs range from low order KVA's to several hundred KVA as a stand alone unit. Using multiple voltage regulators, in combination with fixed ratio

• voltages: 11kV, 22kV , 33kV

Furnace transformers supply power to electric furnaces of various types like Arc furnace, Induction arc, Submerged arc, Rectifier duty & Ladle furnace transformers. In order withstand repeated short – circuit conditions and high thermal stress and to be protected from operational voltages resulting from the arc process, these transformers are designed after considering demanding conditions. The furnace transformer supplying power to furnace has to handle extremely high value currents in the order of kAmps depending upon furnace ratings.
