DISTRIBUTION TRANSFORMERS

Distribution transformers normally have ratings more than 200 kVA, though some national standards can allow for units up to 3000 kVA to be described as distribution transformers. Although there are many custom made Transformers for various voltage ranges. Our principal manufacture & supply a wide range of Transformers of Mineral oil type, Silicon liquid type & Cast resin – Dry type Transformers up to a voltage class of 33kV. While we cater orders exactly to our customer requirements, generally transformers produced fall within 2 categories. Ground mounted &; Pole mounted types. For every application, transformer may require different designs & various parameters and as a result, there is an assortment of configurations. Primarily in addition to the performance properties of the transformers i.e., voltage ratio, losses, impedance, temperature rise etc.

SILICON LIQUID TRANSFORMERS

These types transformers are widely used in Distribution Transformers where the Fire rating is considerably high than Mineral Oil type transformers. Silicone Transformer Oil is an environmentally safe replacement for PCB containing askarels as the dielectric coolant for liquid-filled transformers. Its high thermal stability makes it a good choice for transformers that are located indoors or next to buildings where a thermally stable fluid is more critical.

​​MINERAL OIL TRANSFORMERS

Standard ratings are 100, 150, 200, 250, 300, 400, 500, 630, 750, 1000, 1250, 1600, 2000, 2500, 3000kVA. Other ratings are also available upon request. The windings are made up of high grade electrolytic copper and are concentrically
positioned. Usually copper foil is used for the LV windings.

Insulating oil

The insulating oil generally complies with IEC60296 Class 1. Both inhibited &; uninhibited types can be offered if requested.

CAST RESIN TRANSFORMERS

When researching the advantages of cast resin dry-type transformers, you may find the information available to be somewhat incomplete. More so, only a few of its favourable features are well known, with one of the most noteworthy being its minimal fire risk due to zero oil usage.

1/5

Self-extinguishing, low fire hazard:
The transformer insulation consists of an epoxy resin and quartz powder mixture (an Eco-friendly material). This allows the winding to be flame-retardant, self-extinguishing and almost maintenance free, eliminating the need for costly fire extinguishing equipment. It will also not produce toxic gases, not even under the effects of arcing.

 

Zero oil usage:
The cast resin transformer only needs air to cool. Therefore, it eliminates extra costs and labour for liquid-level checking, oil testing, oil recycling costs, and dielectric testing for moisture absorption. Being almost maintenance free, there are no more on-site oil leaks, which require gasket replacements.

Eco-friendly and safe:

Cast resin transformers pose ZERO risk for oil leaks and pollution of the environment. Transformer explosions during normal operation are highly unlikely due to the self-extinguishable non-toxic substances utilized, even during external fires. They are also suitable for heavy condensation and polluted environments. Cast resin transformers may also withstand abrupt environmental changes from -25ºC to +40ºC in a very short time.

TIP:Always try to ensure that your preferred manufacturer has passed/ obtained C2/E2/F1 tests
according to IEC 60076-11 and that it is approved, i.e. KEMA type tested.

PACKAGE SUBSTATIONS

Increasingly, utilities and companies are looking for simpler, more efficient and easy to install solutions. Package substations offer a fully-integrated, single source option which saves on time, cost and administration. Our package substations include a wide range of product options and transformers from a variety of manufacturers to cater for all utility and industrial sector specifications.

DRY TYPE LV TRANSFORMERS

Dry-type transformers have traditionally offered certain fire-resistant, environmental, and application advantages for industrial and commercial situations.

In Cast Resin Transformers the magnetic circuit and windings are not immersed in an insulating liquid but are cast with an epoxy resin mixture. These special transformers are finding an ever-increasing scope of application for their high-service reliability. Cast resin transformers are a popular choice for use in commercial, industrial and residential sites. These transformers require practically no maintenance and have a much lower environmental impact than traditional oil-immersed transformers. Auto-extinguishing and other safety features make it the obvious choice for indoor applications and other areas with high fire risk.

Different types of Dry Type Transformers:

 

  • Power Distribution transformers

  • Step Up / Step Down transformers

  • Auto Transformers

  • Isolation Transformers

  • Control Transformers
