Product Overview
Heat-Resistant PVC Insulated Wire HIV (60227 KS IEC 07) 300/500V is a single-core flexible stranded copper conductor wire with heat-resistant PVC insulation manufactured to the Korean standard 60227 KS IEC 07 — the Korean national adoption of IEC 60227 Part 7 for heat-resistant PVC insulated cables. HIV = Heat-resistant Insulated Vinyl. The critical differentiator from standard KIV wire (IEC 02, 70°C) is the PVC/E (heat-resistant) insulation compound rated for 90°C continuous operation — a full 20°C above conventional PVC/C, enabling use in high-temperature environments inside appliances, lighting fittings, and motor terminal boxes where standard PVC wire would soften, degrade, and fail prematurely. The "IEC 07" designation in the standard number specifically identifies the heat-resistant PVC category within the IEC 60227 family.
HIV wire is the Korean domestic answer to the European H07V2-K (90°C PVC) and Japanese HIVS (heat-resistant vinyl stranded) wire — a niche product in a very specific cross-section range of only 1.5mm² and 2.5mm², reflecting the specialised application domain: internal wiring of luminaires, heating appliances, and motor connections where elevated ambient temperatures demand heat-resistant insulation but the conductor cross-section requirements are modest (lighting circuits at 1.5mm², small motor power at 2.5mm²). The PVC/E compound retains its dielectric strength and mechanical flexibility at temperatures that would cause standard PVC/C to become tacky and soft, while the finely stranded flexible conductor (Grade 5 per IEC 60228 Class 5 equivalent) enables routing through the tight interior spaces of compact luminaire housings and appliance chassis. The 300/500V voltage rating is appropriate for the internal wiring domain — higher voltage capability is unnecessary inside equipment operating at mains voltage, and the lower rating allows a thinner insulation wall than 450/750V wire of the same cross-section, reducing the overall cable diameter within space-constrained equipment interiors.
PVC/E Heat-Resistant 90°C
PVC/E compound rated 90°C continuous — 20°C above standard PVC/C (70°C). Maintains flexibility and dielectric strength at elevated ambient temperatures.
Grade 5 Flexible Copper
Finely stranded flexible copper conductor. 29 strands (1.5mm²) and 49 strands (2.5mm²) — bends freely through tight luminaire and appliance chassis.
IEC 07 Heat-Resistant Category
60227 KS IEC 07 = Korean adoption of IEC 60227 Part 7 — the specific heat-resistant PVC standard within the IEC 60227 family. "07" denotes 90°C grade.

Typical Applications
HIV heat-resistant wire is the standard internal wiring conductor for Korean-manufactured luminaires, heating appliances, and motor connections where elevated operating temperatures require 90°C rated insulation:
Luminaire Internal Wiring
Standard internal wiring for Korean fluorescent and LED luminaires. 90°C rating handles the elevated temperature inside enclosed fixture housings.
Heating Appliance Wiring
Internal wiring of Korean-manufactured electric heaters, ovens, and cooking appliances where 70°C standard wire would soften and degrade.
Motor Terminal Box Wiring
Motor terminal connections in Korean industrial motors. 90°C PVC/E handles the heat conducted from motor windings through the terminal studs.
Colour-Coded Internal Wiring
6 colours for appliance internal wiring identification: phase (red/white/black), earth (green), neutral (blue), control (yellow).
Korean Appliance Export
