Carriers

Guidelines for the Laying of Cables /
Hoses in the Carrier
Extreme care must be taken when installing supply cables
in cable carriers or flexible conduits.
Please always observe the following:
Only electric cables suitable for use in a cable carrier system should
be used.
Take advantage of our system expertise and ask us to advise on the
appropriate cables / hoses.
Hoses should be highly flexible and may only contract or expand
slightly in length when under pressure.
Information on the properties of hoses with regard to length can be
found in the hose manufacturer’s catalogue.
The weight distribution in the chain stay and / or the conduit
cross section should be as symmetrical as possible!
Cables / hoses should be installed twist-free in the cable carrier!
Cables must be rolled tangentially off rings or drums.
Never take up cables in loops!

Install the cables individually and loosely side by side!
Installing several cables on top of one another and placing cables with
different diameters adjacent to each other should be avoided. In the case
of multi-layer installation, we recommend that provision be made for horizontal
cavity dividers to be placed between the individual layers.
Each cable should be installed in a separate compartment.
Individually produced hole stays or sub-divisions through dividing stays
in the frame stay prevent cables / hoses installed adjacent to each other
from rubbing.
If several cables have to be installed next to each other without dividers,
make sure that the remaining clearance is less than the cable diameter,
to prevent the cables from twisting around each other.

The supply cables must be able to move freely within the cable carrier.
They must not be attached to the carrier, nor should they be bound
together.
Divider bars must always be placed between layers of installed flat
cables.
To calculate the required clearance, the following apply as reference
values:
for round cables: 10 % of the cable diameter
for flat cables:
10 % each of either the cable width or the
cable thickness
for hoses:
20 % of the hose diameter
Highly flexible, thin cables with low bending strength should be installed
loose side by side and arranged in a protective sheath.
The cross-section of the protective sheath should be chosen considerably
larger than the total of the individual cable cross section.
As a reference value for measuring the cross section, each cable should
have a clearance of approx. 10% of its diameter.
