Our Products

Jencore (Unicore)

The ultimate in lightweight and efficient core design, offering lower Watt losses and exciting current with faster assembly time and major cost savings.

Strip-Wound Cores

Traditional C and E cores, according to British or Continental standards and Toroidal cores for use in high accuracy applications such as high voltage and current transformers.

Pressed laminations

We stock an extensive range of E-I and U-I laminations in non oriented silicon steel for use in transformers and chokes, and grain oriented silicon steel for applications where low losses are required.

Amorphous Cores

We can now supply the latest amorphous metal core technology which is ideal for very low loss applications.

Mitre Core Technology

For the highest quality step lap mitred and square cut cores in single or three phase design we manufacture any size to your specifications from 10kVA to 80mVA.

Accessories

We are a ‘one stop shop’ offering all transformer components under one roof, from steel frames and brackets to Nylon bobbins and housings.

Testing

All material is pre-tested on our Soken Iron Loss Tester to ensure quality and authenticity of material used, and all products are tested after production on one of our 5 test benches to guarantee final No Load Losses

Grades of steel we supply with the guaranteed losses

We supply specific core loss curves on request. Please note the final losses of the core will vary and typically losses will be higher in three phase and in single phase cores due to the stack factor and destruction factor of the core. Performance curves (W/kg) available on request.
