Value has started to erode from the market as contractors look for the lowest priced option

comments: ‘First and foremost, a cable tray must act as an effective, resistant and durable support for cables. The mechanical performance of all products and accessories must be tested against the very demanding requirements imposed by the international standard IEC61537.’

Horses for courses Manufacturers have had to consider the environment in which the containment is located and who will be using it. This has impacted upon the composite material used in the production of these systems. Legislation such as The Disability Discrimination Act 2005,

through compliance with Part M and Section 8 of the Building Regulations, has to be addressed. Mike Bancroft, category manager at Schneider Electric, comments: ‘Manufacturers have been responsive to Part M of the Building Regulations by ensuring a range of compliant products are available. For the contractor, it is simply a case of thinking how cable management solutions are used.’ In order to achieve Part M compliance, a majority of

cable containment manufacturers have altered their existing trunking range with contrasting colours, offering a cost effective solution with no compromise on quality, style or durability.

Safe from harm Studies by the National Audit Offi ce (NAO) have suggested that almost 10 per cent of patients have a healthcare acquired infection at any one time. Hospitals and other health care establishments have, therefore, become aware of the need to introduce preventative measures to reduce the outbreak of superbugs such as e-coli and methicillin resistant staphylococcus aureus (MRSA). The cable management sector has a very important part

to play in this. The perception used to be that whilst the switches, sockets and other electrical, air or gas outlets fi tted to the cable management solution were being touched regularly, and could therefore harbour a medium for these superbugs, people rarely came into contact with the actual trunking. The reality is very different, and manufacturers have been actively seeking to enhance antimicrobial integral protection within their products. The use of uPVC compounders can now be used in the

Pier pressure

More than 2.5km of Cablofi l steel wire tray cable management was used to help complete a £51m rebuild of Weston Super Mare’s Grade II listed Grand Pier. The pier had to be rebuilt following a fi re, and the revamped attraction comprises a 400m promenade and a state-of-the-art indoor entertainment venue. The whole structure is lit by LED lights confi gured in a chasing sequence to run down the length of the pier, rise up the three levels of the Pavilion and then back to the shore end. Contractor, Barrie Beard, chose the Cablofi l steel wire tray cable management system to provide ease and speed of installation and corrosion protection. Externally, 200mm marine grade stainless steel Cablofi l with enclosed lids was used to contain both high and low voltage cables.

A spokesperson at Barrie Beard, said: ‘This was fi xed beneath the promenade structure where it was open to the elements and exposed to sea water, so it was specially treated with an anti-corrosion coating by Cablofi l prior to delivery to site and the steel wire tray specialist also provided pre-coated anti-corrosion brackets for the external installation.’

production of the cable management systems rather than just applied as a surface coating. Therefore, it continues to work even if the plastic is scratched or damaged. Jim Fletcher, managing director of Marshall-Tufflex,

comments: ‘We pioneered this approach and have found that the interest in this technology from the NHS, and from private healthcare, is converting to installations all over the UK.’ Stainless steel systems offer an excellent alternative

to antimicrobial systems and are becoming increasingly specifi ed in food factories where hygiene standards are a high priority. Paul-Edouard Courson of Cablofi l adds: ‘Thanks to its open structure and stainless steel fi nish, wire tray can be washed down with detergents and water to maintain high hygiene standards.’
