It is important to prevent cables and hoses from tangling. 5) Cables and hoseswith di ff erent jacket materials must not be allowed to stick together. If necessary, they should be separated. igus ® chainflex ® cables can be combined with all others. 6) Round electrical cables must be secured with strain relief at both ends. In exceptional cases, the cablesmay be fixedwith strain relief at themoving end of the e-chain ® only. A gap of 10-30 times the cable diameter between the end of the bend segment and the fixed point is recommended for most cables. chainflex ® cables can, on the other hand, have strain relief directly at the mounting bracket, as testing has confirmed. We will be pleased to provide you with recommendations for complete e-chain systems ® : bend radii of all cables and hoses, interior separation and service life are then optimised. Distribution rules | Cables and hoses Cables must be able to bend freely. chainflex ® cables can be strain- relieved directly at the mounting bracket Round electrical cables For electrical cables, the round cable is a safe, simple and cost-e ff ective solution for e-chain systems ® . We recommend the following criteria for selecting the proper round electrical cables: ● Small minimumbend radii andmounting heights ● Long service life at minimumbend radius ● Service life expectations for your application (short or long travel, hanging) ● Test data on service life from realistic tests ● Uncomplicated installation process - no hanging, laying out, etc. of cables ● Strain relief integrated directly into themounting bracket ● Flexible shields for shielded cables ● Abrasion-resistant and nonadhesive outer jackets ● Large selection to avoid expensive custom designs. For bus cables and fibre optic cable, special attention must be paid to how e ff ective transmission rates and shielding remain after millions of cycles at the minimum bend radius. Installation and strain relief for round electrical cables 1) Cables must be laid straight, without any twisting. Cables must not be uncoiled from the top of the spool. igus ® chainflex ® cables are immediately ready for placement directly into the e-chain ® . They need not be disconnected or laid out before installation. 2) The cables must be laid so that each individual cable can move freely from side to side. 3) The cables must be able to move freely along the radius. This must be double-checked if the upper run operates at the cable’s maximum bend radius.
