keyboard_arrow_downApplication
In earth, ducts, on cable trays, where no mechanical damages are expected. Constructed for moderate mechanical tensile strains.
As underground distributive or connecting cable in areas with very low ground conductivity, for protection of electric power plants from over voltages caused by lightning or other features at high voltage transmission network.
