Marshall-Tufflex keeps London Underground
in the picture
| 25
Marshall-Tufflex’s MT Supertube FR, formulated for
applications where fire safety regulations are at their
most stringent, was a key component in the upgrade of
London Underground’s Victoria Line OPO CCTV camera
system, with more than five miles (8,100m) of the high-
performance conduit installed.
Manufactured from a special three-layer LSOH conduit,
MT Supertube FR delivered a superior design solution
to protect cables that transmit images of the platforms
to the train driver. MT Supertube FR is an alternative
to steel trunking, offering much faster fit times. It is
supplied in coils of up to 100m and therefore produces
little wastage from cut lengths.
For the London Underground project MT Supertube
FR’s EMC shielding capabilities were of paramount
importance, as the specifying contractor explained:
“We chose MT Supertube for its ability to provide EMC
shielding. It has proved a better way to segregate cables,
which is greatly beneficial in London Underground
applications where there are a lot of unknown cables to
contend with.”
MT Supertube FR meets London Underground’s fire and
materials specification, having undergone a series of
tests conducted against the rigorous requirements set
out by London Underground Ltd.
A Marshall-Tufflex spokesman said: “Having product
specified for use in the London Underground system is
of immense importance to us and a big rubber stamp
for MT Supertube FR. The Underground is a demanding
environment that calls for products of the highest calibre
and performance.”
Steel has a mechanical strength that makes it a robust and durable option
for public areas where there is a high footfall. Our steel trunking provides
Specifiers, Contractors and end-users with reliable, practical systems with
hard-wearing, clean lines and all the advantages of inherent LSOH and
screening properties.
The extra depth provided by Marshall-Tufflex steel perimeter trunking
systems offer increased capacity for power and data services. All earth
bondings are ‘friction fit’ to eliminate the need for unsightly screw fixings.

Aluminium perimeter trunking systems provide the Specifier, Contractor
and end-user with elegant, stream-lined containment that offers the
practical advantages of inherent LSOH and screening properties making
it ideal for industrial environments.
Aluminium is light to handle with a mechanical strength and impact-
resistance that is superior to steel. Extruded sections provide attractive
profiles and products are finished with a high quality, powder-coat that
provides a blemish-resistant surface.
