Anotácia

IEC 60502-2:2014+AMD1:2024 CSV specifies the construction, dimensions and test requirements of power cables with extruded solid insulation from 6 kV up to 30 kV for fixed installations such as distribution networks or industrial installations. When determining applications, it is recommended that the possible risk of radial water ingress is considered. Cable designs with barriers claimed to prevent longitudinal water penetration and an associated test are included in this part of IEC 60502. Cables for special installation and service conditions are not included, for example cables for overhead networks, the mining industry, nuclear power plants (in and around the containment area) nor for submarine use or shipboard application. This third edition cancels and replaces the second edition, published in 2005, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) a simplified calculation procedure for the thickness of the lead sheath and the oversheath; b) a new subclause for the determination of the cable conductor temperature; c) a modified procedure for the routine voltage test; d) a new subclause for a routine electrical test on oversheath; e) modified requirements for the non-metal sheaths including semi-conductive layer; f) modified tolerances for the bending test cylinder; g) the inclusion of a 0,1 Hz test after installation. In addition, the modified structure of the IEC 60811 series has been adopted for this third edition.
