Product Overview
CYKY Cable is a 0.6/1kV PVC-insulated, PVC-sheathed unarmored power cable widely used in Central and Eastern European markets for fixed indoor and outdoor installations. The designation "CYKY" follows the Polish/German cable naming convention where C = copper conductor, Y = PVC insulation, K = cable, Y = PVC sheath. It is the regional equivalent of Germany's NYY and the UK's BS 5467 unarmored PVC cable — all referencing the same physical construction under different national standards.
Regional Naming Equivalents
These cable designations all refer to the same construction (copper conductor, PVC insulation, PVC sheath, 0.6/1kV, unarmored). The difference lies solely in the national standard to which compliance is declared, and minor local preferences in core identification colors:
| Region | Designation | Key Standard | Notes |
|---|---|---|---|
| Poland / Central Europe | CYKY / CYKY-O / CYKY-J | PNE 34 7659-3, HD 603 S1 | O = flat, J = with reduced earth core |
| Germany / DIN Region | NYY | DIN VDE 0276-603 | Also NYY-J (with earth), NYY-O (without) |
| France / NFC Region | U-1000 R2V | NF C 32-321 | PVC/PVC equivalent, often with numbered cores |
| United Kingdom | BS 5467 PVC Unarmored | BS 5467 | Same construction, BS-specific color code |
| International / IEC | IEC 60502-1 PVC Cable | IEC 60502-1 | Generic international designation |
| China | YJV / VV (GB/T 12706.1) | GB/T 12706.1 | VV = PVC/PVC; YJV = XLPE/PVC |
Cable Construction
Copper Conductor
Plain annealed copper, Class 1 (RE, solid) or Class 2 (RM/SM, stranded) to EN 60228 / IEC 60228. RM = round stranded; SM = sector-shaped compacted stranded for larger cross-sections.
PVC Insulation
PVC compound DIV 1 per HD 603 S1. Rated for continuous conductor temperature of 70°C, with short-circuit tolerance up to 160°C for maximum 5 seconds.
Inner Bedding
Extruded elastomeric or plastomeric compound, or plastic binding tape, applied over the laid-up cores to provide a circular bedding surface for the outer sheath.
PVC Outer Sheath
PVC compound DMV 1, black (standard). Flame-retardant, resistant to UV, oils, acids, and alkalis. Other colors available on request. CPR fire class Eca per EN 50575.

Technical Specifications
RE = round solid conductor (Class 1). RM = round stranded conductor (Class 2). SM = sector-shaped compacted stranded conductor (Class 2). For cables marked "+" (e.g. 3×35+25), the second value is the reduced neutral/earth cross-section.
