OPTOHARD protective pipes

OPTOHARD protective pipes

Single-walled protective pipes are primarily intended for the mechanical protection of optical and coaxial cables installed in trenches and channels (construction and reconstruction of transmission lines).

the mechanical properties of HDPE protective pipes and the low friction coefficient of the inner surface enable trouble-free cable installation over long distances (up to 3 000 m under ideal conditions)
cables can be installed into the pipe using pulling or blowing technology

Material

high-density polyethylene (HDPE)

Pipe design

outer wall - smooth
inner wall - smooth or longitudinally grooved
pipe ends are fitted with protective plugs to prevent dirt ingress

Heat resistance

handling temperature: +5 ºC to +50 ºC
operation temperature: -40 ºC to +70 ºC
storage temperature: -40 ºC to +60 ºC
extra care must be taken during handling at temperatures below 0 ºC

Mechanical resistance

high mechanical resistance even at low temperatures
resistance to compression is min. 750 N/200 mm (code 750)
impact resistance is normal (code N)

Pipe connection

mechanical couplings

Colour

on request, pipes of the same colour can be differentiated using one, two or three longitudinal stripes along the pipe at 90º intervals
minimum colour stability of 10 months under outdoor exposure

Identification

standard identification
at the customer´s request, the logo and the manufacturer´s name can be replaced with another logo and name
the lettering is standard black and min. 4 mm in size
the identification is printed in 1 m intervals

Storage

small coils must be stored in horizontal position
maximum stacking height 2 m
shelf life is 36 months when stored indoors and protected from direct sunlight
shelf life is 9 months when stored outdoors in Central European conditions; on request, enhanced UV resistance can extend the shelf life to 18 months
