FAQ

Questions engineers ask first

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

What does the suffix 'ek' mean in YnOGYek?
In Polish mining cable nomenclature (PN-G-90006), 'ek' denotes an overall concentric copper screen (ekran miedziany) consisting of helically applied copper wires bound with a counter-helical copper equalizing tape over a semi-conductive bedding layer. Each production drum undergoes 100 % conductor DC resistance verification, insulation
How does YnOGYek differ from YnOGYekm?
YnOGYek uses a concentric copper wire + copper tape screen ('ek') for fixed or semi-mobile machinery wiring, whereas YnOGYekm uses a flexible braided/composite copper-elastomer screen ('ekm') engineered for higher mechanical flexing endurance. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness
Why is the 'ek' copper screen required in methane-hazardous coal mines?
If an external rock impact penetrates the outer Yn sheath, the concentric copper screen ('ek') immediately intercepts the fault before the live cores can short-circuit to each other, tripping the central earth-leakage relay without external sparking. Each production drum undergoes 100 % conductor DC
Does YnOGYek include an inner bedding beneath the copper screen?
Yes. An extruded PVC inner bedding and semi-conductive layer separate the insulated cores from the concentric copper wires, ensuring a circular core profile and preventing wire indentation into the core insulation. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging,
