Pipes for extra rough terrain
Our cable protection pipes are specially designed for tougher terrain where high strength is a requirement. They are manufactured from high density polyethylene (PEHD) and have a ring stiffness (over 16 kN) that is significantly higher than standard requirements (8 kN). The pipes have a high resistance to external pressure and stress and are also resistant to most chemicals. They are also sealed to prevent the penetration of ground water and soil or sand. Quite simply, Extena’s cable protection pipes provide highly reliable protection for electrical cables – and thus offer optimal weather protection.

SRE-P (protection, pipes, extra difficult conditions – plastic) is used for surface laying in difficult terrain.

Grooved interior
Extena’s SRS and SRE-P cable protection pipes have a grooved interior to reduce friction when pushing through power cables. We see this as a big advantage. The use of cable protection pipes instead of a sand bed also provides more efficient propulsion, safer pipelaying and lower total costs.

Quality at every stage
Our products undergo very thorough quality control, both in our own testing laboratory and at external inspection institutes. In this important task, we collaborate closely with the research Institute RISE. Another aspect of our quality assurance is that we have full traceability of the materials that we use.
