We were asked by our client to provide a complete electrical enclosure design which was to include full electrical system integration. This was part of Docklands Light Railway passenger system. The purpose of the enclosures was to provide power supply for all trains. A number of the power supplies were containerised to sit trackside while others were installed into buildings.
The enclosure design needed to accommodate our customers electrical design & integrate with all site interface requirements so a variety on interfaces were required. Our client provided an electrical specification highlighting such areas such as creepage and clearance, ventilation and IP rating requirements. This enabled us to make good progress with the mechanical outline of the cubicle. Once we had an outline cubicle design we then started to work closer with our customers electrical Engineers on the system integration as this was least risk under a tight delivery schedule.
The enclosures had to adhere to all the safety specifications such as low smoke zero halogen paint coatings and non metallic materials as set out in the specification and all non metallics adhered to UL94/V0 fire and smoke specifications.
