FAQ

Questions engineers ask first

What is the difference between the 'ekm' screen in YnOGYekm and the 'ek' screen in YnOGYek?
In YnOGYek, 'ek' is a helical copper wire screen bound with a copper equalizing tape. In YnOGYekm, 'ekm' (ekran miedziany modyfikowany / elastyczny) uses a fine copper wire braid integrated with a semi-conductive elastomeric/polymer layer so the screen will not birdcage or shift under repeated bending and torsional movement.
Why does YnOGYekm allow a tighter bending radius (6×D fixed / 10×D flexing) than YnOGYek?
Because the 'ekm' braided composite screen expands and contracts symmetrically around bends without open helical wire gaps or stiff copper equalizer tapes, it tolerates tighter bending radii on monorail loops and mobile mining skids. Each production drum undergoes 100 % conductor DC resistance verification,
Is YnOGYekm suitable for 0.6/1 kV VFD drives in underground mines?
Yes. The combination of a 100 % coverage semi-conductive layer and a ≥ 85 % tinned/bare copper braid provides superior high-frequency common-mode EMI containment from kilohertz to tens of megahertz. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and
Can YnOGYekm be supplied with a green-yellow protective earth core (-żo)?
Yes. All multi-core YnOGYekm sizes are available either with a dedicated green-yellow core (YnOGYekm-żo) or without a green-yellow core (YnOGYekm-o) where the concentric screen and separate pilot/earth cores are used. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and
