Product Range

cast-resin-1
cast-resin-2

Power Cast Resin Encapsulated Transformers. Manufactured by our partners, we are able to supply cast resin transformers for applications such as Rectifier, Converter, Traction, and Distribution Transformers with throughput capacities up to 5 MVA, and highest system voltages up to 24 kV.

Since its incarnation in 1951, T&R has steadily expanded its product range of liquid filled transformers, incorporating Mineral Oil, Midel 7213 and Silicon Oil.

Redesigned and manufactured in Guildford, our HV/HV transformers range up to 10MVA, 36 KW and our HV/LV transformers range up to 7.5MVA, 36KW.

Complex winding configurations are not unusual for Transformers and Rectifiers limited. Winding variations such as Zig-Zag windings, triple windings including a tertiary and primary phase shift transformers.

In addition to providing a transformer suitable to meet the clients requirements and expectations, we are also able to supply a full test procedure including:-

  • Full Wave and Chopped Impulse Tests
  • Temperature Rise Test
  • Zero Phase Sequence Impedance Tests
  • Sound Pressure Test
  • Short Circuit Test * (External laboratories are utilised).

In many applications the transformers need to be suitable for overloads and harmonic warming. In both cases Transformers and Rectifiers Limited have a wide experience of such applications and would be pleased to discuss these details further with yourselves.

One of the major costs associated with replacement transformers is the installation cost. At Transformers and Rectifiers Limited, we can provide a facility where the replacement transformer would be designed and manufactured as a complete replica of the existing unit, so replacement of HV and LV cables can be minimised. In some cases, it is possible to utilise the existing HV and LV cable boxes so power cables are not effected at all.
