FAQ

Questions engineers ask first

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

What does the 'W' in (N)TSW 3.6-6 kV indicate?
'W' stands for wetterfest (weather-resistant) in the German VDE designation system. It denotes an ozone-, UV-, and moisture-stabilised heavy-duty polychloroprene rubber sheath designed for year-round outdoor trailing duty in quarries, gravel pits, and floating dredgers. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and sheath dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
How does (N)TSW 3.6-6 kV differ from NTSCGEWÖU 3.6/6 kV?
(N)TSW 3.6-6 kV uses semi-conductive field grading and three split interstitial protective earth conductors without individual metallic copper wire screens or high-speed drum anti-torsion braiding, making it lighter and simpler to terminate for semi-mobile quarry feeders and floating dredger pontoons. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and sheath dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
Can (N)TSW 3.6-6 kV be used on floating gravel and sand dredgers?
Yes. Floating suction and bucket-chain dredgers feeding 6 kV shore transformers are one of the primary applications for (N)TSW 3.6-6 kV, as its cross-linked 3GI3 EPR insulation and polychloroprene jacket tolerate continuous pontoon splashing and freshwater immersion. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and sheath dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
How is the protective earth arranged inside (N)TSW 3.6-6 kV?
Rather than using a single asymmetric fourth core, the protective earth is divided into three equal Class 5 tinned copper conductors positioned in the three outer interstices between the phase cores, preserving a circular cross-section and balanced impedance. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and sheath dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
