01 Description

ProtectorLine^® KN (I) are single-layer pipes of a special spiral-type shape contributing to high ring stiffness indicators with a minimal product weight.

Can be supplied with a steel drawstring in the pipe for cable pulling.

years 0 + Long service life
(at least 30 years)

Key advantages

Increased strength: high ring stiffness up to SN48 and possibility to be laid in trenches (with compaction needed), under roads, crossings
Flame-resistance (FV-0 category)
Flexibility: small-radius bending is possible
Mechanical strength throughout the entire service life
Resistance to aggressive and chemically active environments
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 open-trench installation, including along routes with complex geometry, where pipes shall have both flexibility and mechanical strength, as well as for applications requiring flame-resistant inner layer.

Laying method

Open-cut installation
