NTSKCGWÖU KON 0.6/1 (1.2) kV Mining Loader Cable with Split Concentric Earth
Heavy-duty 0.6/1 (1.2) kV trailing and reeling cable based on DIN VDE 0250-813 for LHD loaders, shuttle cars and mobile haulage: three power cores plus three KON units, each a 1.5 mm2 EPR pilot core inside a concentric split tinned-copper earth screen, around a central aramid element, with an anti-torsion braid between 5GM5 polychloroprene sheaths. Three configurations from 3×16 to 3×50 mm2.
Underground LHD loaders, shuttle cars and mobile face haulage machines drag and reel their power cable thousands of times, and the earth and pilot circuits are what keep the protection system aware of cable damage. NTSKCGWÖU KON is a 0.6/1 kV (Um 1.2 kV) mining loader cable based on DIN VDE 0250-813 that rearranges those protective circuits: instead of a separate earth core and two pilot cores, it carries three concentric KON units in the interstices between the three power cores.
Each KON unit is a 1.5 mm2 EPR-insulated pilot core surrounded by a concentric screen of tinned copper wires that forms one third of the split earth conductor, 16/3 mm2 or 25/3 mm2. The power cores and KON units are laid around a central aramid tension-relief element, and an anti-torsion textile braid sits between the inner and outer heavy-duty polychloroprene sheaths of type 5GM5. Three configurations are offered: 3×16+3x(1.5 KON+16/3 KON), 3×25+3x(1.5 KON+25/3 KON) and 3×50+3x(1.5 KON+25/3 KON) mm2.
The reference catalogue for this construction contains two inconsistencies: its text gives a minimum bending radius of 2.3 x D while its mechanical table gives 4 x D, and its 50 mm2 resistance of 0.565 Ω/km matches a 35 mm2 conductor rather than the 0.393 Ω/km maximum for a tinned Class 5 50 mm2 conductor in IEC 60228. TEBAOFLEX builds to the IEC 60228 conductor values and confirms bending radius and all final data on the factory datasheet at order stage.

NTSKCGWÖU KON (NTSKCGWOU KON) Frequently Asked Questions
What does KON mean on NTSKCGWÖU KON?
KON refers to the concentric units in the interstices: each is a 1.5 mm2 EPR-insulated pilot core surrounded by a concentric screen of tinned copper wires that forms one third of the split earth conductor.
Which configurations are available?
Three: 3x16+3x(1.5 KON+16/3 KON), 3x25+3x(1.5 KON+25/3 KON) and 3x50+3x(1.5 KON+25/3 KON) mm2.
Why does the page mention catalogue discrepancies?
The reference catalogue gives 2.3 x D and 4 x D for bending radius and prints a 50 mm2 resistance that matches 35 mm2. TEBAOFLEX applies IEC 60228 conductor values and confirms bending radius and final data on the factory datasheet.
What are the MOQ and lead time?
The minimum order quantity is 50 m and the manufacturing lead time is 7 to 45 working days, depending on configuration and quantity.
