FAQ

Questions engineers ask first

What does 'Fo' denote in YKGYFoyn / YKGYFoyn-żo?

In Polish PN-G-90006 nomenclature, 'Fo' denotes an armour of galvanized round steel wires (pancerz z drutów stalowych okrągłych) bound with an open counter-spiral steel tape to prevent wire birdcaging during installation. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging,

Why is YKGYFoyn required instead of YKGYFtZnyn in inclined drifts and vertical shafts?

Flat steel tapes ('FtZn') are lapped at a short pitch and cannot carry axial tension without opening up and stretching the copper cores. Round steel wires ('Fo') are stranded at a long lay angle specifically to carry the longitudinal weight of the cable in inclined drifts and vertical shafts.

When should I order YKGYFoyn-żo versus YKGYFoyn (without -żo)?

Order YKGYFoyn-żo when an internal green-yellow insulated protective conductor is required inside a 3-, 4-, or 5-core cable. Order YKGYFoyn (or YKGYFoyn-o) for 3-wire insulated-neutral IT mining systems where earthing is carried via the armour and external bonding. Each production drum undergoes 100 %

What if my inclined roadway or shaft requires electrostatic screening ('H') or 6 kV rating?

For methane-hazardous roadways or 3.6/6 kV and 6/10 kV medium-voltage networks requiring round steel wire armour, specify YHKGYFoyn. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and high-voltage AC or DC dielectric testing before release with an EN 10204
