Riser Teck Vertical Suspension Banding In Place 1

[JulesBeland]

Manufactures advise the maximum self support length and or pulling tension details for this type of cable pulled vertically up by its phase conductors. I have not found any information on the vertical support intervals once pulled. It's become a standard in the mining industry to band the outer to a bracket at some interval. This banding supposedly compresses the armour enough to secure the conductors within. Seems that a few assumptions are made as to the tension applied by the banding used and to the compressive abilities of the armour to secure the conductors. Would someone have come across any information on the vertical support requirements & means for Riser Teck?
Our application is for 200 meter vertical with a total of 20 meters running horizontally.
Thanks

Riser Teck is constructed with a ribbed inner jacket to grip the conductors and interlock with the armour. (Armour: Canadian spelling;- TECK was originally developed for use in Canadian mines.)
