Specialcare should be taken to avoid any damage caused byexcessive tensioning during installation.The distance between fixing points should beselected according to cable type and probability ofvibration but should not exceed 450mm.Where cables are installed below cable trays, ladderor supports, the fixing distance for securing the cableshould be in accordance with the table below.OVERALL DIAMETER OF CABLE NON-ARMOURED ARMOUREDEXCEEDING NOT EXCEEDING CABLESCABLES(mm)(mm)(mm)(mm)- 8 200 2506 13 250 30013 20 300 35020 30 350 40030 - 400 450* All information above is intended as a guide onlyissue 13.1 Triangle Flexible Cables51
