NYM Cable

nym Cable Specification

Application:: NYM cable is designed for wiring inside buildings, available in single or multicore versions with grey PVC sheathing. Suitable for use in dry, damp or wet areas and can be installed in, on or under plaster, brickwork or concrete.
Standard:
CHARACTERISTICS:: Voltage Rating: 600/1000 Volts; Temperature Limits: -30°C to +70°C; Minimum Bending Radius: As per cable manufacturer datasheet Should not be installed at temperatures below : 0°C
CORE IDENTIFICATION:: 2 core - Brown Blue; 3 core - Brown Blue Green/Yellow; 4 core - Brown Blue Black Green/Yellow; 5 core - Brown Black Grey Green/Yellow Blue
Advantage:: 1. Excellent electric and mechanical characteristics.; 2. Best Resistance chemical corrosion and heat-ageing,environment stress and flame-retardant.; 3 Simple in structure,Convenient to use.; 4. Reduce costs.
