10 reasons to choose GrayBar no8

Points Heating, Signalling Distribution and Accessories

8. GrayBar have successfully designed and manufactured many innovative products to supply projects to Network Rail and TFL, including:


GrayBar were selected to design and build the Points Heating System for HS1 High Speed Rail Link. The GrayBar system had two variants, the first one with both the control and six 6.5KVA integral transformers, and the second version having a separate transformer cubicle, housing 12 integral 6.5 KVA transformers.


Crossrail engaged with GrayBar at a very early stage to look at using the GrayBar Self-Regulating Points Heating System on this prestigious project. On many of the sites selected, space was at a premium, and having all of the control gear and transformers in one cubicle was the ideal solution. Collaborating closely with Crossrail’s Design Team, GrayBar fine-tuned their system to meet the specification required.
