This video clip demonstrates the strength of our Emperor trefoil cleats under short-circuit conditions.

A short-circuit of 59kA RMS (118kA peak) is passed down the three-phase arrangement for a period of 0.1 seconds, showing the cables being forced apart by the physical forces present under such conditions and demonstrating the need for correct cable restraint.

This video shows the same short-circuit (59kA RMS) passed down a similar cable arrangement, but fastened with stainless steel cables ties and aptly demonstrates the need for using the correct cable cleat for your application.

This vido shows our popular Alpha trefoil cleat undergoing short-circuit testing to and four different fault levels, comparing these results with similar test where the cables are restrained with cable ties.

Fault levels tested, with cables cleated every 600mm:

30kA RMS

35kA RMS

40kA RMS

45kA RMS

Ideally suitable for all commercial and industrial applications and fast becoming the industry leader in securing single-core cables in trefoil formation, the Alpha is suitable for installations where modest levels of short-circuit protection capability are required.
