What is the Inner and Outer Jacket Diameter of (N)TSKCGEWÖU 3×150+3×25/3 3.6/6kV Splittable Earth Cable?
(N)TSKCGEWÖU 3×150+3×25/3 3.6/6kV cable with split three-part earth conductor is approximately 65 mm (2.56 inches), with a standard tolerance window of ±3.0 mm producing a permissible range of 62.0–68.0 mm. The inner jacket (the intermediate protective layer between the insulation and outer sheath) typically has a nominal thickness of approximately 0.8–1.0 mm, contributing to overall diameter build-up but not typically measured as a separate “inner diameter” in engineering specifications because the inner jacket is not a defined outer boundary—it is a layer embedded within the cable structure. The outer jacket (the final thermosetting rubber compound layer) has a nominal thickness of approximately 2.5–3.0 mm, providing the cable’s mechanical interface with the environment. The approximate total weight of this cable is 8,200 kg/km (5,510 lbs/1000 ft), with copper content approximately 4,560 kg/km. It features three 150 mm² Class 5 tinned copper main phase conductors, three strategically distributed 25/3 mm² split earth conductors for electromagnetic symmetry, a 3GI3 high-dielectric EPR insulation system rated for continuous 90°C operation, an anti-torsion braid reinforcement layer, and a 5GM5 thermosetting halogen-free outer sheath providing extreme abrasion and tear resistance.
