Demo: Batu Hijau Mine Cable Pull
A real-world scenario: 240 mm² copper XLPE single-core cable through a 300-metre decline with 4 bends (2 horizontal, 1 convex, 1 concave). The route includes a 15° incline on the main straight, testing both gravity-assisted and gravity-opposed pull directions.
- Cable: 240 mm² Cu XLPE, single-core, 150 mm conduit
- Route: 300 m total — 4 bends (90° each), 15° incline
- Analysis: Bidirectional with SWBP, WCF, and jam ratio checks
