NTSWÖU-J Cable for Low Voltage Trailing Applications
The NTSWÖU-J Cable is a 0.6/1kV flexible trailing cable designed for mobile power supply routes in mining, tunneling and heavy industrial environments. Its class 5 tinned copper conductors, EPR-based 3GI3 insulation and rugged 5GM5 outer sheath make it suitable for equipment where the cable may be moved, dragged, bent and exposed to oil, moisture and mechanical wear.
Key Engineering Features
- Flexible class 5 conductor: Stranded tinned copper conductors support repeated movement and help reduce corrosion risk in humid or underground environments.
- 3GI3 insulated cores: The EPR-based insulation provides a robust electrical layer for low-voltage equipment power supply.
- Ground core arrangement: Cores are laid up in contact with each other and interstitial ground cores, supporting compact construction and protective grounding.
- GM1b inner sheath: The special elastomeric inner sheath helps stabilize the laid-up cores and improves the cable’s mechanical integrity.
- 5GM5 outer sheath: The heavy-duty elastomer sheath is suited to trailing service where abrasion, oil, flame risk and outdoor exposure must be considered.
- Clear site identification: Yellow or black sheath options help match site visibility and equipment marking requirements.
