Despite that, for re-routing and repair often desirable install cables the same type. Although the demand for paper insulated cables has decreased, for re-routing and repair often desir- able install cables the same type. For this purpose, nkt cables has kept the manufacturing facilities and know-how provide the optimum solution. Similar the external gas pressure cables service experience with the internal gas pressure cables is also very satisfactory. The conductors are insulated with lapped and mass impregnated paper insulation.16 external gas pressure cable according VDE standard copper conductor paper insulation lead sheath reinforcing tapes laid-up cable cores flat steel wire armour steel pipe polyethylene covering NP The external gas pressure cables have been devel- oped the early 1930ies. Over suitable bedding armour flat steel wires applied.

Thousands kilometres are satisfactory service European high voltage networks. considerable number installations with this cable type service today. The three core cable pulled into a steel pipe which filled with nitrogen gas bar overpressure. deviation the external gas pressure cable the nitrogen gas forms part of the cable insulation. They have proven their reliability many decades. For this pur- pose, nkt cables has kept the manufacturing facilities and know-how provide the optimum solution. With the gas pressure acting the oval shaped cable cores, formation voids prevented, giving the cable the required electrical strength. Like the external gas pressure cables, the demand for new installations has decreased significantly. Each insulated core is separately lead sheathed
