Temporary site cables are custom-made, quick-connectable cables for temporary use in the high-voltage network, for example, during repair work on overhead lines or in transformer stations when converting networks. The cables feature multi-strand copper conductors with cross-sections of 150 sq. mm and 300 sq. mm and are similar to high voltage cables, but the high-purity insulation allows for a reduced insulation thickness. This results in a compact cable with reduced outer diameter and weight. Temporary site cables are supplied with flexible pre-fabricated and pre-tested silicone rubber terminations which facilitates use in any position. The cables are available in 110, 132, 150 or 230 kV and are produced in lengths of 50 m to 500 m. They can carry a current up to 750 A and can be connected in parallel to double the capacity.
