EN 50143 applies to single core cables of rated voltages up to and including 5/10 kV (Uo/U) used with electric signs and high-voltage luminous-discharge-tube installations. These cables are for use in installations complying with EN 50107. The particular types of cables are specified in Clauses 7 to 10 of this standard.
