Fixing device to secure cables in formation or To attach and secure cables within installations. October, 2014 Cable Cleat Guide 5 Variations of cleats available There are many different types and styles manufactured from many different materials available October, 2014 Cable Cleat Guide 6 Manufacturers worldwide Cooper B Line CMP Products Dutchclamp Ellis Patents Oglaend Aeron Prysmian DSSB Intertech Power Electric October, 2014 Cable Cleat Guide 7 International standards of cleats BS EN61914:2009 = IEC 61914:2009 October, 2014 Cable Cleat Guide 8 Definitions and terminology of cleats Cable formation MULTIPLE ( 5 or more ) QUAD SINGLE TWIN TREFOIL October, 2014 Cable Cleat Guide 9 Definitions and terminology of cleats System fault current – maximum potential current that could flow during fault conditions. RMS fault current – root means square value of current typical the effective current level Peak fault current – the peak current level reached during fault conditions which can be from 2.2 to 2.6 times rms current. Crest or Peak factor – system factor used to calculate maximum expected peak fault current usually between 2.2 and 2.6 October, 2014 Cable Cleat Guide 10 Definitions and terminology of cleats Cleat spacing – distance between cleat centres Straps – are cleats which are not secured to the installation infrastructure Cleat spacing Cleat spacing October, 2014 Cable Cleat Guide 11 Definitions and terminology of cleats Cleat spacing many factors govern the maximum distance between cleat centres for safe correct installation. • Cable manufacturer’s installation recommendations • System fault current • Cable diameter • Cable formation • Cleat type • Installation axis – vertical, horizontal • Supported by tray, ladder or basket The correct way is to calculate the maximum distance based on the Force that each cleat can withstand, using the formula. October, 2014 Cable Cleat Guide 12 Installation method Installed and fixed to infrastructure by fixing bolt(s) in base plate October, 2014 Cable Cleat Guide 13 Typical installations Installed on cable ladder or unistrut channel frame either vertically or horizontally October, 2014 Cable Cleat Guide 14 Typical installations Installed on cable tray either vertically or horizontally October, 2014 Cable Cleat Guide 15 Typical forces acting on cleats Forces which act on cleats under fault conditions Trefoil formation experiences the highest amount of force during fault conditions Cable centres As force is proportional to the distance between cable centres that the greater or larger forces are generated or seen when the cable centres are closer together Incorrect cleating MOVIE October, 2014 Cable Cleat Guide 16 118,000 amps (118 kA) peak Incorrect cleating MOVIE October, 2014 Cable Cleat Guide 17 Estremo Cleats test MOVIE October, 2014 Cable Cleat Guide 18 176,000 amps (176 kA) peak October, 2014 Cable Cleat Guide 19 Typical applications for cleats Oil, Gas and Petrochem industries Rail - overland underground infrastructures Electricity distribution networks Windfarms Industrial installations Mining October, 2014 Cable Cleat Guide 20 Non cable applications for cleats Flexible and corrugated conduits and tubes Plastic water pipes Copper pipes Stainless or rigid conduit systems and pipe runs for industrial and dairy industries October, 2014 Cable Cleat Guide 21 Factors effecting the choice of cleats 1.
