FAQ

Questions engineers ask first

How do all the letters in 'YHKGYFoyn' decode?
Under Polish PN-G-90006 rules: 'Y' = PVC core insulation; 'H' = semi-conductive/electrostatic screen over the cores; 'K' = power cable; 'G' = multi-wire flexible/stranded copper conductors; 'Y' = extruded PVC inner bedding; 'Fo' = galvanized round steel wire armour bound with a counter-spiral steel tape; and 'yn' = flame-retardant mining PVC outer sheath.
How does YHKGYFoyn compare with British Coal MGM 109 Type 3123 and MGM 118 Type 6110?
Both are screened, round-steel-wire-armoured medium-voltage underground mining feeder cables with flame-retardant PVC outer sheaths. YHKGYFoyn is built to Polish standard PN-G-90006 for 0.6/1 kV, 3.6/6 kV, and 6/10 kV systems using multi-wire 'G' copper and special PVC insulation, whereas MGM 109/118 uses BS 6708 1.9/3.3 kV and 3.8/6.6 kV ratings with 90 °C EPR insulation.
Why is YHKGYFoyn mandatory for inclined drifts and vertical mine shafts?
When a heavy 6 kV or 10 kV feeder is installed in a vertical shaft or steep incline, the weight of the cable must be supported by the armour wires clamped in shaft cleats. Only round steel wire armour ('Fo') provides the axial tensile strength to prevent conductor elongation.
What is the role of the counter-spiral steel binder tape over the 'Fo' armour wires?
In Polish 'Fo' armour construction, an open counter-helical steel tape is wound over the round galvanized steel armour wires to hold the wires tightly in place during vertical shaft lowering and prevent birdcaging under axial compression. Each production drum undergoes 100 % conductor DC
