The description relates to a power cable with several power cores as a sector conductor and an optical core in an unoccupied sector. The optical core takes the form of a bunched cable of a plurality of stainless steel tubes with optical fibers (LWL tubes). The cable provides an integrated solution for power and data supply for a network. The cable could be used with advantage as a power cable for local systems with an operative voltage of 1 kV. One LWL tube can be fitted per connection. The stranding of the four-sector cable (1) consists of three single-wire sector lines (10, 10', 10") and the optical core (50). The core filling spaces are filled with strands (30, 31) of differing thickness. In an outer filling there is a further tube (42) with two optical fibers. The cores of the concentric conductor are in corrugated array (CW screen). The concentric conductor can be removed in domestic connections without damage and laid aside, thus providing free access to the cable cores. |
