Gantry lighting controls along the entire length of Britain's latest
motorway are housed in IP67 protected, high impact resistant
polycarbonate enclosures, supplied by Fibox's subsidiary in the UK. There
are 36 sign gantries housing a total of 221 lighting units on the new M6
Toll road, and Fibox EK series housings are used throughout to house a
range of electrical lighting controls.
The electrical subcontractor on this project, H Woodbine, used Fibox EK
TH enclosures to house automatic cut-out devices and double-pole MCBs for
every single light on each gantry, and EK UH enclosures to house the
electronics and electrical components required to control each of the
gantry's lighting functions. Project consultant, Atkins specified Fibox
because it believed the enclosures would cope with the environment in
which the M6 Toll road lighting operates.
Reliability is obviously key, while high IP rating and durability are
important factors, comments Atkins' Brian McCann. Another
consideration was the ease with which the panel building contractor could
populate the enclosures and integrates them into the entire lighting
scheme.
Ease of integration was aided by the large range of accessories and
fittings that are supplied with the EK range, including covers, hinges,
internal mounting options, glands and cable entry systems.
