N.B. Hoisting Grips: 1 / every 100ft vertical run. For heavier runs, such
as 1-5/8” 4AWG, use 2 hoisting grips / every 200ft vertical run)
HYBRIFLEX Bending
The minimum-bending radius should be strictly observed. [See product spec sheet]
HYBRIFLEX cable should be bent manually with a force applied in a distributed manner, pressing
carefully while the hand slides along the cable [see diagram 1]. Avoid rapid, sharp motions.
Avoid any tight micro bends near the fiber end face as micro bends can cause broken fiber and
increase insertion loss. [See diagram 2&3].
HYBRIFLEX cable, with copper outer shield, is easy to bend, but must be handled carefully, to avoid damage
to DC power wires.
Do not twist the cable, e.g. if changing from vertical to horizontal runs [See diagram 4]
Do not leave the Hybrid cable hanging in a long free space, e.g. during the installation under a
platform. In adverse conditions additional protective measures may have to be taken [for example see
picture 1].
Protective measures:
temporary fixation of the cable
As shown from side (upper) and
top (lower) view, do not swing
the cable horizontally creating a
twist in the vertical run
As shown from side view, rather
form a large bow and pull and
guide the cable horizontally
without creating any twist
Pull carefully
bit by bit
While pressing, slide your hand
