FAQ

Questions engineers ask first

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

How do I read a size notation such as 1×150/25 mm² on NTMCGCWÖU?

In the notation 1×150/25 mm², the first number (1×150 mm²) is the cross-sectional area of the single Class 5 tinned-copper phase conductor, and the second number (25 mm²) is the cross-sectional area of the concentric tinned-copper wire screen surrounding the insulated core. Standard sizes from 16 mm² to 120 mm² carry a 16 mm² concentric copper screen, while 150 mm², 185 mm² and 240 mm² carry a 25 mm² concentric copper screen.

Does 'GC' in NTMCGCWÖU mean the cable has a separate ground-check core?

No. Under DIN VDE 0250-813 German cable nomenclature, 'NTMCGCWÖU' denotes a flexible single-core medium-voltage rubber cable ('NTM') with semi-conductive field-control layers ('C'), EPR insulation ('G'), a concentric copper wire screen ('C') and an oil/weather/flame-resistant heavy-duty elastomer sheath ('WÖU'). It contains a single phase conductor and one concentric screen — there is no auxiliary ground-check or pilot conductor.

Where is single-core NTMCGCWÖU used instead of 3-core NTSCGEWÖU?

NTMCGCWÖU is designed for short, space-constrained medium-voltage connections where routing three separate single-core cables (minimum fixed bending radius 6 × OD, e.g. 130–275 mm) is much easier than bending a large 3-core cable (OD 45–100 mm). Typical duties include internal links between switchgear cubicles, connections to mobile transformer substations, transformer-house droppers, traction equipment and large medium-voltage drives.

How should single-core NTMCGCWÖU cables be arranged and bonded in a 3-phase circuit?

A three-phase circuit uses three separate NTMCGCWÖU cables (one per phase), laid in trefoil or flat formation with non-magnetic cleats to withstand short-circuit electrodynamic forces. At terminations, each cable requires a screened medium-voltage stress-control kit matched to the insulation diameter (which increases from 3.4 mm wall at 3.6/6–6/10 kV to 5.5 mm at 12/20 kV and 8.0 mm at 18/30 kV), with the concentric copper screen earthed according to the substation's single-point or both-ends bonding scheme.
