(N)3GHSSHCH Tunnelling Underground Mining Cable Installation Instructions

   

✔ Firstly, Before installation, inspect (N)3GHSSYCY/(N)3GHSSYHCH Cable for damage and verify specifications match operating requirements.
1. Avoid dragging, sharp friction and excessive bending;
2. follow the specified minimum bend radius.
3. Keep cables away from high-temperature sources and corrosive substances.

✔ Secondly, during laying, ensure proper tension to prevent overstretching the steel wire braid armor.
1. For underground and mobile use, fix cables securely with dedicated fixtures.
2. Terminate cores strictly per electrical standards, guaranteeing tight connections and good insulation.

✔ Lastly, after installation, conduct insulation and continuity tests.
Do not operate the cable until all inspections pass. Wear protective gear during work and comply with local electrical safety regulations at all times.
