The outer conductor of this cable is constituted
of a corrugated tube (spiral winding).
This construction allows perfect shielding and
bendability while respecting large bending radius.
The foam dielectric provides excellent loss and
low return loss levels.
This cable will be advised for feeder and jumper
assemblies in cellular networks as well as
applications requiring high performance level
on long distances.
The anti-UV LSZH (Low Smoke Zero Hallogen)
material is also flame retardant and allows this
cable to be used for indoor public areas as well
as outoor installations.
APPLICATION NOTE
CORRUgaTED CablE 1/2"
(Cellflex 1/2" Spiral)
p/N: C291 994 170
(Cellflex HCF 1/2" CuH-50 AlCu)
This is the smallest semi-rigid cable size
proposed by RADIALL.
Its reduced size allows it to be easily
handformable during integration operations.
