FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What does 'FtZn' mean in YHKGXSFtZnyn?
In Polish cable nomenclature (PN-G-90006), 'Ft' stands for flat steel tape armour (pancerz z taśm stalowych płaskich) and 'Zn' indicates hot-dip zinc galvanizing (ocynkowanych) for corrosion resistance against saline mine water.
Why is YHKGXSFtZnyn limited to a 45° incline while YHKGXSFoyn is used up to 90° vertical?
Flat steel tapes ('FtZn') are wound at a short pitch angle to resist radial crushing, so they cannot bear axial self-weight tension in steep shafts. Round steel wires ('Fo' in YHKGXSFoyn) are laid at a long helical pitch specifically to carry the vertical suspended weight of the cable down a 90° mine shaft.
When should I choose YHKGXSekFtZnyn over YHKGXSFtZnyn?
Choose YHKGXSekFtZnyn whenever the cable operates in a methane-hazard roadway or at 6/10 kV to 12/20 kV, where individual copper screens ('ek') around each XLPE phase core are required.
What factory routine tests and certificates are supplied with YHKGXSFtZnyn?
Every production drum of YHKGXSFtZnyn undergoes 100 % conductor DC resistance measurement at 20 °C, high-voltage AC/DC dielectric withstand testing, and dimensional verification per PN-G-90006 / PN-93/E-90401 / IEC 60502-2, supplied with an EN 10204 3.1 inspection certificate.
