Product Overview
PVC Insulated Flexible Wire KIV (60227 KS IEC 02) 450/750V is a single-core Class 5 flexible stranded copper conductor PVC insulated wire manufactured to the Korean standard 60227 KS IEC 02 — the Korean national adoption of IEC 60227 for PVC insulated flexible cables. KIV = Korean Insulated Vinyl — the Korean domestic designation for what the European harmonised system calls H07V-K and the international standard calls IEC 60227 Class 5 flexible wire. The "Grade 5 conductor" designation (Korean equivalent of IEC 60228 Class 5) uses fine multi-strand copper construction with strand counts from 28 wires (1.5mm²) to 121 wires (16mm²), producing a cable that bends freely through appliance interiors, switchgear compartments, and control panels without kinking or spring-back. PVC/C insulation compound provides 70°C continuous operation, 160°C/5s short-circuit withstand, and a 4×D minimum bending radius — the smallest bending radius class for fixed flexible wiring.
KIV occupies a specific position in the Korean building wire hierarchy: it is the flexible counterpart to the solid IV wire (60227 KS IEC 01) and the heat-resistant HIV wire (IEC 07, 300/500V), designed for general interior wiring of buildings and electric appliances below 450/750V where the wire must follow curved and tight routing paths. The six standard insulation colours — black, white, red, green, yellow, blue — cover all Korean electrical code identification requirements for phase, neutral, and earth conductors when used in combination. Unlike the EU harmonised system which uses brown/black/grey for phases and blue for neutral, the Korean domestic market continues to use the Asian standard colour scheme (red/white/black for phases, green for earth) per KS C IEC 60445 — KIV wire is manufactured in the full colour palette to service both domestic Korean and export markets that have not adopted the IEC brown/blue scheme.
At 100m per roll in export wooden case packaging, KIV is the high-volume Korean flexible building wire for electrical wholesalers and panel builders. The 6-size range (1.5-16mm², 21-170 kg/km) covers the full span of domestic and light commercial building wiring — from 1.5mm² lighting circuits (21 kg/km, bending to 11mm radius) to 16mm² sub-main feeders (170 kg/km, bending to 27mm). The inclusion of a minimum insulation resistance at 70°C column (0.010-0.0046 MΩ/km, decreasing with cross-section) provides the thermal-state leakage current data that indoor dry-condition building wires typically omit — a useful specification for Korean installations where humid summer conditions elevate leakage current in long conduit runs.
Grade 5 Flexible Copper
28-121 strands (1.5-16mm²). Korean Grade 5 = IEC 60228 Class 5. Fine multi-wire construction — bends freely through appliance and panel interiors.

4×D Tight Bending
Tightest bending class for fixed flexible wire. 11mm bend radius (1.5mm²) to 27mm (16mm²) — ideal for appliance and control panel routing.
70°C Insulation Resistance
0.010-0.0046 MΩ/km thermal-state data — critical for Korean humid summer installations where leakage current must be calculated.
6 Sizes 1.5-16mm²
1.5mm² (21 kg/km) to 16mm² (170 kg/km). The standard Korean domestic building wire range. 100m/roll, export wooden case.
