We recommend the optimal separation layout of the cables and hoses in the E-Chain ® , but you, the customer, are still afforded the final choice. It is possible, for instance, to maintain minimum distances between bus and motor cables and mix pneumatics, electric and hydraulics in the same compartments. Cables and hoses with very different diameters should be laid separately. The separation is achieved using modular separators. Cables and hoses must under no circumstances have the opportunity to tangle. Therefore, the clearance height of a compartment with several similar cables or hoses next to one another must not amount to more than one and a half times the cable/hose diameter. Expressed in rules, this means: Rule 1: if D1 + D2 > 1.2 x E-Chain ® inner height, no separation between the two cables/ hoses is necessary. Two cables/ hoses should never be left unguided on top of one another or be allowed to become tangled. Rule 2: if d1 + d2 ≤ 1.2 x E-Chain ® inner height, a vertical separator or a horizontal shelf must be used to reduce the inner height. Thereby preventing the entanglement of d1 and d2. The reason for this rule is: The cables and hoses must be laid so that they can move freely at all times and so that no tensile force is exerted at the radius of the E-Chains ® . For high-speed applications and high cycles, cables or hoses must not be laid on top of each other without horizontal separation. The standard values for this are: Travel speed over 1.64 ft/s (0.5 m/s) and cycles over 10,000 p.a. igus ® interior separation offers a safe solution for this situation. In addition to the quality of the cables used, the arrangement of each Cable/hose within the E-Chain ® and the space allowed, are important for the service life of the system. Various separation options enable the adaptation of the E-Chains ® to the specific requirements of each respective application. Generalised rules such as "No more than 80% of the clear space of Energy Chains ® is allowed to be used" no longer make sense given the complexity of present-day applications. In this chapter, we give you detailed recommendations. Due to the variety of the application parameters, we strongly recommend you take advantage of our free consultation services.Simply give us a list of your cable requirements (or merely the required electrical or other services) and you will receive our recommendation. Maximum cable and hose diameters The maximum cable and/or hose diameter corresponds to the inner height of the selected E-Chain ® /e-tube, with additional minimum clearance. This minimum clearance would be, for example, 10% for electrical round cables, 20% for hydraulic hoses. An E-Chain ® is ideal if a minimum lateral gap to the next cable or hose has been factored in. Depending on the nature of the cables, the dynamics, and the expected service life, more clearance must be allowed. In specific cases, clearances may be altered further. You may talk to us about this. Hydraulics and electric cables are separated from one another in this example Orderly cables with igus ® interior separation Rules for: Maximum cable diameters Separation Bend radius Electrical cables need at least 10% clearance space all around, hydraulic hoses need 20% The maximum conduit diameter is specified for each series on its respective chapter D1 + D2 > 1.2 x hi d1 + d2 ≤ 1.2 x hi d1 + d2 ≤ 1.2 x hi Clearance space "all around" for round electrical cables Clearance space in % for various cables Cables clearance space "all around" Electrical round cables 10% Electrical flat cables 10% Pneumatics 5-10% Hydraulics 20% Media hoses 15-20%
