Transformer Wiring

Permanoid Ltd is a British manufacturer of transformer wiring.

This range of heat resisting wires is suitable for temperatures between 20°C & 105°C and is resistant to most insulating varnishes, lubricating oil,  hydraulic oil and many alkalis. 

 

They are ideal for use as tails in transformers and electric motors or wherever encapsulation and high temperatures are needed.

 

The conductors are tinned annealed copper to facilitate soldering.

 

The special high temperature PVC compound (BS7655 TI3) avoids the hardening, embrittlement and fracture suffered by standard wire and cable compounds due to interaction with oils and chemicals
