Cable 3 X50

This document provides specifications for a 3-core copper cable with a rated voltage of 3.6/6 kV. The cable has a stranded copper conductor, XLPE insulation, a semi-conductor screen, PVC separation sheath, galvanized steel wire armour, and a PVC outer protective sheath. The cable is designed to operate at temperatures up to 90°C, withstand flames and hydrocarbons, and be resistant to UV light aging. It has theoretical electrical characteristics including current ratings, reactance, short-circuit withstand, voltage drop, and impedance.
