It is assumed that the raise of temperature of the inner conductor when submitte
35、d to the maximumcurrent under nominal ambient conditions does not affect the mechanical and electrical properties of the cable (details are under study).4.2 InnerconductorThe conductor shall meet the requirements of Subclause 4.2 of EN 50117-1, and shall be solid or tube. Individual wires can be pla
36、in or metal coated. Dimensions shall be in accordance with the detail specification. There shall be no joint made subsequent to the last drawing operation. 4.3 Dielectric The dielectric material(s) shall be in accordance with Subclause 4.3 of EN 50117-1 and shall consist ofpolyolefin materials,with
37、EN 50290-2-23 (polyethylene), EN 50290-2-25 (polypropylene) or any relevant part of EN 50290-2-XX. Dimensions shall be in accordance with the detail specification. Unlessotherwise specified, the nominal diameter over the dielectric should be one of the preferred values, namely 2,9 mm, 3,7 mm, 4,8 mm
38、 and 7,2 mm.4.4Outer conductor or screen The construction and material of the outer conductor and/or screen shall meet the requirements ofSubclause 4.4, items b), c), f) or g) of EN 50117-1. Where option b) is used, a double braid layer isrequired. Forbraid constructions or helically wound wires, th
39、e braid angle shall be between 15 and 45. The coverage factor shall be greater than or equal to 65 %, or, when the cable is provided with a metal foil, greater than or equal to 25 %. These values are also valid for cables with two bi-directional layers ofhelically wound wires.Dimensions shall be in
