Power Cables with Extruded Insulation and their Accessories for Rated Voltages from 1 kV (Um = 1.2 kV) Up To 30 kV (Um = 36 kV) – Part 1 : Cables for Rated Voltages of 1 kV (Um = 1.2 kV) and 3 kV (Um = 3.6 kV)
Specifies the construction, dimensions and test requirements of power cables with extruded solid insulation for rated voltages of 1 kV (Um = 1,2 kV) and 3 kV (Um = 3,6 kV) for fixed installations such as distribution networks or industrial installations. This standard includes cables which exhibit properties of reduced flame spread, low levels of smoke emission and halogen-free gas emission when exposed to fire. 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), submarine use or shipboard application. The main changes with respect to the first edition relate to insulation and oversheath thickness requirements, and inclusion of constructions and requirements for halogen free cables with reduced flame propagation and low levels of smoke emission.
