FAQ

Questions engineers ask first

How do YnKGY-żo and YKGYyn-żo relate in Polish mining nomenclature?
Both designations refer to 0.6/1 kV PVC-insulated ('Y'), flexible copper ('G'), flame-retardant mining PVC-sheathed ('Yn' or 'yn') underground mining power cables ('K') with a green-yellow protective conductor ('-żo'). Some Polish factories place the flame-retardant sheath prefix at the front ('YnKGY-żo') while others place it at the end ('YKGYyn-żo').
Why does YnKGY-żo include an extruded inner filler bedding?
In underground gassy mines, cables entering Ex d flameproof switchgear must form a pressure-tight seal inside the elastomeric compression gland ring. The extruded inner PVC bedding fills all core interstices so gas cannot migrate through the core lay. Each production drum undergoes 100 %
What does the suffix '-żo' mean?
In Polish electrical standards, '-żo' (żyła ochronna zielono-żółta) indicates that one of the insulated cores is a green-yellow protective earth conductor (equivalent to 'G' in VDE '5G10' notation). Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and high-voltage AC
When should I use armoured YKGYFtZnyn or YKGYFoyn instead of unarmoured YnKGY-żo?
Use unarmoured YnKGY-żo on protected messenger-wire hooks and inside substation chambers where low weight and Class 5 flexibility are needed. Where the cable is exposed to rock-fall impact or shaft tension, specify steel-tape armoured YKGYFtZnyn or steel-wire armoured YKGYFoyn. Each production drum undergoes 100
