DRY TYPE TRANSFORMERS
     -
Vacuum Pressure Impregnated

 

Applications :

  • Public and high rise buildings.

  • Windmill applications.

  • Provision of electrical power for marine propulsion and distribution systems.

  • Drives, frequency converters and rectifiers to provide complete solutions for pumps, fans, compressors, conveyors, drilling packages, mills, thrusters, gas turbines, generators, mixers and so on.

  • Railway fixed traction installations, underground stations, cranes and seaports, offshore platforms among other applications.

Dry Type Vacuum Pressure Impregnated Transformers are designed & tested to comply with national & International Standards IS/ BIS/ ANSI/ IEC & IEEE.

Vacuum Pressurization Impregnation (VPI) is Impregnation under Vacuum follewed by Pressure to ensure void free Impregnation. It is so called because of the use of Vacum and Pressure cycles during the process.

Main Advantages :

  • Less space and civil work needed

  • No special safety features required (fire detection)

  • Maintenance free

  • Longer transfomer life due to low thermal and dielectric ageing

  • Low cost of installation and maintenance

  • Can be installed closer to the point of consumption reducing load cables losses

Salient Features :

  • High dynamic short circuit & mechanical strength.

  • Good impulse withstand strength

  • Low partial discharge - VPI process ensures void free insulation system

  • Resistance to temperature fluctuations

  • Moisture ingress resistant & immune to polluted atmosphere

  • Initial higher cost than that of oil cooled

  • Ease of maintenance

  • Environment friendly

OIL IMMERSED TRANSFORMERS

 

Salient Features :

  • Oil Filling through Oil Impregnation procedure (Adapted generally for EHV transformer). It leads to enhanced life.

  • Mineral Oil or Silicone Oil or as per requirement

  • Electrolytic Grade Copper winding

  • Low loss CRGO Silicon steel for core

  • Step lap construction & mitered joints for core

  • Designed for extreme system supply variations and ambient temperature

  • Losses as per star rating, (if required) as per BEE

  • Low Power Loss and Low Noise

PACKAGE/ COMPACT/ UNITIZED SUBSTATIONS

 

Applications :

They are ideally suited for new residential and commercial complexes as it can be placed on Ground, partially or totally below/ above ground level. Mainly used by power utilities, Multiplexes, Hotels, Hospitals, Shopping Malls, Software Parks, Residential Complex, Airport etc.

Main Advantages :

  • Total economy in cost

  • Low civil/ foundation cost

  • Reduction in logistic costs as USS is delivered as a single unit

  • Reduced Electrical losses as USS can be provided near load center

  • A high degree of safety and operational reliability is achieved by HT and LT switchgears and protective relays to avoid overloading

Salient Features :

  • Design conforms to IEC 62271-202, IEC 130 (1995) and IS 14786: 2000 standards

  • Fully compartmentalized design

  • IP23/ IP33 degree of protections available

  • Designed to withstand electrical impulses, thermal and dynamic stresses

  • Compact and occupies less floor space

  • Easy to install, operate and maintain

  • Tailored configuration to meet customer requirements
