FAQ

Questions engineers ask first

What does 'FtZn' mean in the Polish cable designation YKGYFtZnyn?
In Polish cable nomenclature (PN-G-90006), 'Ft' stands for flat steel tape armour (pancerz z taśm stalowych) and 'Zn' indicates that the steel tapes are hot-dip galvanized (ocynkowane) to resist corrosion in humid, saline underground mine galleries. Each production drum undergoes 100 % conductor DC
When should I specify YKGYFtZnyn (steel tape armour) versus YKGYFoyn (round steel wire armour)?
Specify YKGYFtZnyn for horizontal galleries, cross-cuts, and buried trenches where the primary mechanical hazard is radial impact or crushing from falling rock and where axial tensile pulling forces are low. For vertical shafts, inclined drifts (> 15°–45°), or subsiding ground subject to longitudinal tension, specify round-wire armoured YKGYFoyn.
Why does Polish mining use galvanized ('FtZn') rather than uncoated ('Ft') steel tapes?
Underground coal and copper mine waters are frequently highly mineralized and corrosive. Galvanizing ('Zn') prevents rust expansion and hydrogen evolution beneath the outer 'yn' sheath if the jacket is abraded. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and
What is the screened counterpart to YKGYFtZnyn?
Where an additional electrostatic/semi-conductive screen ('H') is required for methane-hazardous roadways or medium-voltage (3.6/6 kV, 6/10 kV) networks, specify YHKGYFtZnyn. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and high-voltage AC or DC dielectric testing before release with an
