Powerstar offers a wide range of liquid filled distribution transformers with mineral oil or synthetic fluid filled equipment designed to suit the medium/high voltage power distribution requirements of the customer. The liquid filled transformers are robust and are suitable for installation indoors or outdoors in harsh environments. LV MV HV transformers require very little maintenance and have a long life span of up to 35 years.

Also referred to as liquid cooled distribution transformers as they are cooled by the liquid (usually oil) contained within the transformer. Liquid distribution transformers have “K” factor ratings which allow them to cope with the rigours of harmonic disturbance experienced in solar, wind power or drive systems.

When upgrading your MV HV electrical power infrastructure it is vital that you are aware of what your main focus is and work with a transformer provider who can help you to achieve your objectives. For instance, if your main target is to decrease costs then the dry distribution transformers are discounted straight away as they are renowned for greater operating losses than the liquid filled transformers.

Taking this into account liquid filled transformers are used widely in the utility industry.

Features & Benefits

  • Low initial transformer cost
  • Long service life of up to 35 years
  • Low load losses
  • Large choice of styles, ratings and types
  • Can be custom built to meet customer requirements
  • Typical primary voltages: 3.3kV, 6.6kV, 11kV, 11-6.6kV DUAL, 33kV
  • Typical secondary voltages: 280V, 315V, 400V, 415V, 433V, 480V, 690V

Liquid filled distribution transformers are also often utilised in situations where a higher capacity is required as they are noticeably more efficient in this application.

The cooling properties of liquid filled transformers are often smaller compared to a dry type transformer of the same rating and they can often be found outdoor as a result of their additional cooling and insulation properties.

Regardless of which distribution transformer you decide is best for you it is imperative that you keep up with a solid maintenance and annual inspection schedule to enable the transformers to perform safely and to their full potential.
