FAQ

Questions engineers ask first

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

How does (N)TMCGC11Y differ from standard (N)TMCGCWÖU or NTMCWÖU?
(N)TMCGC11Y includes both radial semiconducting stress control + concentric copper earth screen ('GC') AND replaces the standard polychloroprene rubber sheath ('WÖU') with an 11YM1 Polyurethane ('11Y') outer sheath. Unscreened NTMCWÖU has no metallic screen and requires spacing from grounded metal; (N)TMCGC11Y is touch-safe when its copper screen is grounded and offers 3× higher abrasion resistance thanks to the PUR jacket.
Can (N)TMCGC11Y be terminated with standard heat-shrink or cold-shrink MV indoor/outdoor terminations?
Yes. The outer semiconducting elastomer layer ('G') is engineered as an easy-strip ('strippable') screen that peels cleanly off the 3GI3 EPR dielectric without scoring, compatible with standard Raychem, 3M, Pfisterer Connex and Euromold Class 5 lugs and terminations.
Why choose a flexible Class 5 EPR/PUR cable over a standard N2XSY (XLPE/PVC) cable inside MV switchgear?
Standard N2XSY has a stiff Class 2 conductor and a 15 × OD minimum bend radius (~500 mm on 185 mm²), making it nearly impossible to route inside compact GIS switchgear, mobile container transformers or wind turbine nacelles. (N)TMCGC11Y bends to 5 × OD (~170 mm) without stressing transformer bushings.
How should the concentric copper screen ('C') be bonded on long single-core parallel runs?
On short switchgear/transformer jumpers (< 30 m), bond the copper screen at both ends. On longer parallel trefoil runs carrying high current, single-point bonding (with a sheath voltage limiter at the open end) may be used to eliminate circulating screen currents.
