ProtectorLine® KOR pipes
Dual-layer, flexible, corrugated, up to 1 kV
For installation by the trenching method
01 Description
ProtectorLine® KOR are dual-layer corrugated pipes made of polymer compound with an external signal layer in red colour and a smooth inner layer that facilitates the process of pulling cable in the duct.
Can be supplied with a steel drawstring in the pipe for cable pulling.
Design
- Outer layer: marker
- Inner layer: smooth
* Pipes in other colour are available upon request.
(at least 30 years)
Key advantages
- Resistance to aggressive and chemically active environments
- The smooth inner layer eases the cable pulling
- Flexibility: small-radius bending is possible
- Mechanical strength throughout the entire service life
- Light weight: construction vehicles are not required for installation
02 Application area
Mechanical protection of power cable lines, control cables, and FO communication lines
Intended for mechanical protection of power cable lines, control cables, and FO communication lines. Used for installation by trenching method.
Laying method
- Open-cut installation
