Extena is Sweden’s leading player in the development and manufacture of cable protection pipes within its product category. Our products have a significantly higher quality and ring stiffness than standard requirements and offer both more efficient laying, lower total costs and a safer service life compared to traditional laying of power cables in a sand bed. As more and more grid companies realize the benefits of cable protection, our business in this area has grown dramatically. Today we supply cable protection for both large and small projects across the country.

Higher ring stiffness than standard
This is a big difference in the quality and ring stiffness of the cable protection pipes available on the market. The standard for the ring stiffness of cable protection pipe SRS is 8 kN, which in our opinion is far too low for pipelaying without a sand/rock flour bed. To ensure a long and safe service life, we manufacture our pipes with a ring stiffness of over 16 kN, in other words significantly higher than the standard.

Be aware that low price pipes are imported into the market that exactly meet the requirements for ring stiffness. There is a risk that these pipes will not withstand stress over time. However, with Extena cable protection pipes you can be sure that you will get a secure system with a long service life.

Pipes for 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.
