UNILINE is a hose developed for use in indirect cooling systems for underground electric power cables. This hose prevents drops in electrical power transmission efficiency.

UNILINE is available in a nominal diameter of 70 mm to 150 mm, and a nominal pressure rating of 0.5 MPa to 1.0 MPa. It withstands high pressures, while being lightweight for easy transport and handling during installation. It can be supplied in lengths of up to 600 meters and allows reduced pipe-laying costs.
