Dry Type Transformers

Product image

We design and manufacture custom built, specialised transformers for a wide range of industry applications with manufacturing operations in Australia and the United Kingdom.

Environment friendly dry type, gas pressurised transformers are non-explosive, non-polluting and require a minimum of maintenance with insulation levels equivalent to oil/liquid filled transformers.  The hermetically sealed tank protects the core and coils from moisture, dust, explosive gases and corrosive atmospheres.

Overview

Description

We can supply dry type transformers to the following specifications:

  • Primary voltages: 3300V to 22000V
  • Secondary voltages: 415V to 1100V
  • Temperature ranges: 150oC average winding rise, 220oC winding hot spot
  • KVA ranges: 200kVA to 8000kVA
  • Frequency: 40-60Hz

With over 6400m2 of floor space, our custom built facility based at Tomago NSW, offers in-house core slitting and cutting, coil winding ability to 10000kg, vacuum oven drying facilities, voltage withstand to 350kV, impulse testing to 1000kV and a large hard stand area.

The winding capabilities include horizontal winding machines and the capacity for two vertical winding machines.

The state of the art high voltage test bay includes 1000kV/75kJ impulse testing, while the routine test bay is equipped to perform tests up to 80MVA 132kV.

In addition, the facility has the capacity for oil storage, handling and filtering for 80,000 litres, coil winding up to 3 metres in length and 2 metres in diameter.

Typical applications include:

  • Industrial switchrooms
  • Materials handling and mineral processing
  • Petrochemical, gas and hazardous areas
  • Tunnel boring machines
  • Public, commercial and industrial buildings
  • Utilities and infrastructure distribution systems
  • Underground coal/metalliferous mines
  • Light and heavy rail applications
  • On board transformers for rail vehicles, electric shovels and draglines

A complete transformer rewinding and general repair service is also available as an economical alternative to replacement.  Refurbished transformers are fully tested, certified and covered by warranty.

We also specialise in the design and manufacture of oil filled transformers.
