points edit

Electric heaters are fitted to the railway track switches to prevent failure or malfunction of the switch under conditions of ice or snow.

The heaters are supplied from a single phase 240 V / 110 V isolating transformer, usually located at the trackside adjacent to the heater installation. For safety reasons the isolating transformers are wound with dual secondary windings each at 110 V and electrically separate from the other.

The transformers are petroleum jelly filled, and enclosed in an galvanised sheet steel tank to BS EN 60947 classification IP 54 or better. Typical ratings available are 3 kVA, 5 kVA, or 10 kVA.

All units comply with Network Rail/Railtrack specification RT/ES/40045 Issue 3 October 2001.
TEC also manufactures signalling and telecommunications transformers to BR specification 924A.

UK Established Since 1918

The Claude Lyons Group was founded in the UK in 1918 and is still in private ownership. Since our early days we have been innovators in areas related to voltage and power control and more recently in energy saving and harmonic mitigation. Operating as a global exporter with many years experience we can justifiably call ourselves a world leader in the field of voltage stabilisers, power conditioning and uninterruptible power supplies (UPS)
