CABLING
Megger finds fault on cables of all types A
n ideal choice for electrical contractors who work on both power and communications installations, Megger’s new TDR1000/3 time domain reflectometer (TDR) can be used on an exceptionally wide range of cable types. It is suitable, for example, for use on low-voltage power cables, including concentric types, as well as on coaxial and twisted pair data and voice communication cables. Despite its versatility, the TDR1000/3 is simple to use as it incorporates an auto set-up feature that makes it easy for even inexperienced users to obtain good results.
New technology used in the TDR1000/3 also means that locating cable
Cable management, made better in the UK by Crabtree.
rabtree has introduced two new aesthetically pleasing cable management solutions to its already extensive range of quality electrical products. A compact range of PVC trunking and accessories called COMPAK together
C with a high cabling
capacity range called MAXPAK that fully meet the requirements for Cat 5E, 6, 6A and 7 cables, is now available after being entirely designed, developed and manufactured in the UK and Europe. The new Crabtree trunking has a clean unobtrusive style that helps it blend into its surroundings, and with a clever open access design, provides full cable support during cabling for both top and bottom compartments. Both variants come with truly flexible internal and external corners to provide for the everyday reality that walls are not always 90º true.

New clip design secures MT’s Steel Trunking as flexible friend of installers
e-designed steel perimeter trunking solutions System 130 and System 170, from market-leader Marshall-Tufflex, now offer specifiers and installers greater in-use flexibility thanks to a new clip system allowing the trunking to be divided into multiple compartments on site.

On both systems the internal ‘C’ rail has been replaced with a multipurpose clip that slots quickly and easily into position. The clips can be used to hold dividing fillets, transforming the trunking from a single channel to two or three compartments. The clips also securely position power and data cables ensuring a 50mm distance between each and act as an additional lid support.

As Unistrut® celebrates its 90th anniversary; we pride ourselves as much today on the quality of our products as we did in the 1920’s. By only using quality steels backed by certification and testing all our products to relevant BS standards, we are so confident in our total systems performance we back it with a 10 year warrantee*, we also understand that provenance of the materials we use can be a major factor, with this in mind we clearly stamp on the side of all our Channel a unique code (QBN code) that enables traceability of the steel provenance back to the manufacturer and the production batch, giving you the confidence that you get the performance we state and we also stamp Unistrut® on every component to make them easy to identify.
Engineering excellence is at the core of our business and we understand the challenges that modern projects create. It’s often the case that an off-the-shelf solution is unable to answer all of your needs and requirements – especially when there are specific location, timing, or environmental issues to consider, in these situations a bespoke or tailored solution can offer you the flexibility and cost effectiveness you need to successfully deliver your project. Our ability to assess, design, build and provide ongoing project lifetime support for our systems has proven to be invaluable on global major projects.

n this increasingly competitive market with copies and lower quality unbranded metal framing products and their lack of a traceable steel pedigree and certification, can you afford to run the risk of specifying or fitting non-safe products?
Yes it may look as though you save a few pence per meter up front, but when it gets right down to what’s important to you, those few pence saved could end up costing you far more when product performance lets you down and causes a failure or far worse a safety issue.
When it comes to the quality of the metal framing products that support your power cabling and essential facilities, by not making sure you specify a suitable performing product or not checking that what you specify is fitted, you run the risk of installing products not fit for purpose or worse unsafe.
