HO5Z-K 300/500 V HO7Z-K 450/750 V

H05Z-K harmonized cable combines flexible stranded copper and low-smoke, halogen-free (LSZH) insulation for safe internal wiring in residential and commercial buildings. Its enhanced flame retardant and low-toxic smoke properties ensure safer performance in confined spaces. Ideal for switchgear, distribution boards, lighting circuits and appliance wiring under HAR standards.
