West India Quay Cubicle
Using 5KVA transformers, one per heater strip. allowed GrayBar to supply heaters 22 metres in length. This system was installed on a number of sites including; West India Quay, Woolwich Extension & Woolwich Arsenal.
This system could also be a solution when installing High Speed Points, as it offers the following advantages:
- Only 4 heaters strips per point, as opposed to multiple heater kits
- Less cabling as only one 8 core cable per point outgoing from the cubicle
- Only one TCB required
- Less construction and installation time, as transformers are integral within the cubicle
- Reduced maintenance and spares
- Simpler RCM options, less hardware required, whilst still being able to monitor all the heaters and control gear
