Multi-core SWA cable installation in vertical risers.

Des
Hi


I have just had a conversation with a contractor who has stipulated that as part of a vertical cable installation it is a requirement to put a kink in the cable every 5-7m. The reason behind this is they say it helps with the distribution of the weight on high vertical risers.


I have never heard of anyone doing this? can someone please advise me if this is now a requirement, or point me in the right direction for clarification, i.e. is it in any of the guidance notes.


Regards

    This can be done for single cables in trunking in big vertical runs where the cable is alternatively weaved through regular support posts within the trunking but an armoured cable would be regularly fixed to support its weight making what they have suggested unnecessary.
