Cores

The transformer cores are built from cold reduced grain orientated steel laminations with mitered joints, working at a flux density of 1.74T. The laminations are supplied with a phosphate coating to keep losses to a minimum. The core is supported with strong channel end frames, insulated from the core and protected with oil resisting varnish.

Windings

The windings are constructed from paper insulated copper. Cooling of the windings is achieved by the appropriate amount of ducts; ensuring local hot spots are avoided.

Tanks

The tanks are made from mild steel plate of sufficient thickness and stiffened to enable the complete transformer to be lifted or jacked safely, without distortion. Cooling radiators with isolation valves are fitted to the tank side.

On Load Tap Changer

The on load tapchanger will be supplied with 17 positions for linear regulation of the tapping windings.

The tapchanger would be an automatic, + 10% to - 10% in 1.25% steps. We have also included for a 100VA, 11000/110V VT to be mounted in the transformer tank and a tank mounted tapchanger, including a tank mounted automatic tapchanger/fan control panel.

Fittings

The transformer will be supplied with a rating and tapping connection plate, earthing terminal, prismatic oil level gauge, lifting lugs, thermometer pocket, drain valve, jacking points, Buchholz relay, Qualitrol pressure relief device, winding temperature indicator and magnetic oil level gauge, all with contacts wired back to the auxiliary wiring terminal box and 3 x 1000mm diameter fans.

Terminations

HV - 3P, 3G, bottom entry cable box, complete with porcelain bushings, suitable for Raychem termination HV neutral - 1P, 1G, bottom entry cable box, complete with porcelain bushings, suitable for Raychem termination LV - 3P, 6G, bottom entry cable box, complete with porcelain bushings and suitable for air clearances

Testing

Routine tests will be carried out in line with IEC 60076-1. The rated withstand voltage levels will be in line IEC 60076 Part 3 section 5.3. Our offer does not include for any type testing.

Paint Finish

Dark Admiralty Grey
