FAQ

Questions engineers ask first

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

What does the VDE type designation 2XSEYQY mean?
'2X' denotes cross-linked polyethylene (XLPE) core insulation; 'SE' denotes individual semi-conductive and 16 mm² copper screens over each phase core; 'Y' denotes the extruded PVC inner bedding; 'Q' denotes the ≥ 90 % galvanized steel wire braid armour; and the final 'Y' denotes the red flame-retardant outer sheath.
Why is 2XSEYQY significantly lighter and smaller in diameter than 3GSEYQY?
Because 2XSEYQY operates at 6/10 kV (Um = 12 kV) with high-dielectric-strength XLPE ('2X') insulation rather than 18/30 kV EPR ('3G'), its radial insulation wall is thinner. For example, 3×70/16 mm² is 54.5–60.2 mm OD and 6,030 kg/km in 2XSEYQY (6/10 kV), compared with 74.5–82.4 mm OD and 9,760 kg/km in 3GSEYQY (18/30 kV).
Is 2XSEYQY suitable for semi-mobile tunnel substation relocation?
Yes. While it uses Class 2 stranded copper conductors and is not a reeling drum cable, its braided galvanized steel wire armour ('Q'), individual copper tape core screens ('SE') and 15 N/mm² / ±25 °/m mechanical ratings allow repeated unhanging, pulling forward and re-hanging as tunnel boring or mine faces advance.
What cable should I use if my 6/10 kV tunnel machine has a motorized reeling drum?
For motorized reeling drums on TBMs, scooptrams, roadheaders or excavators at 6/10 kV, specify Class 5 flexible rubber reeling cable NTSCGEWÖU 6/10 kV or (N)TSCGEWÖU-TL.
