(N)TSKCGEWÖU Cable for Mining Trailing Applications
The (N)TSKCGEWÖU Cable is a 3.6/6kV medium voltage trailing cable for mobile mining machinery and heavy material handling equipment. It is built for applications where the cable is pulled, reeled, exposed to abrasion and moved with large machines such as excavators, dumpers and crushers.
Key Engineering Features
- Medium voltage trailing design: Suitable for 3.6/6kV systems with 7.2kV maximum voltage, giving mobile equipment a robust power supply cable for mining duty.
- EPR insulation system: 3GI3 EPR insulation supports flexible medium voltage service and is combined with semiconductive conductor and insulation screens for electrical field control.
- Earth and pilot core arrangement: Three power cores, two earth cores and one pilot core help support equipment grounding and control/safety circuits in mobile machine operation.
- Central reinforcement: Kevlar reinforcement in the center improves mechanical stability when the cable is used with mono spiral reels or cylindrical reels.
- Anti-torsion braid: Polyamide thread braiding between the internal and outer sheath helps reduce torsional stress during repeated movement and reeling.
- Heavy-duty sheath: 5GM5 synthetic thermosetting compounds provide resistance to tear, impact, abrasion, oil, UV, ozone and harsh outdoor exposure.
Cable Construction
- Conductors: Annealed flexible stranded tinned copper, class 5 to IEC 60228 and HD 383.
- Separator: Semiconductive tape between conductor and insulation where required.
- Conductor screen: Semiconductive layer.
- Insulation: Ethylene-propylene rubber compound type 3GI3 to DIN VDE 0207 Part 20.
- Insulation screen: Semiconductive layer, maximum resistivity 200 Ω·m.
- Core cable: Three power cores, two earth cores and one pilot core laid up on a cradle separator with Kevlar reinforcement in the centre.
- Semiconductive covering: Semiconductive layer over the core cable.
- Internal sheath: Synthetic thermosetting compound type 5GM5 to DIN VDE 0207 Part 21.
- Anti-torsion braid: Polyamide thread braid between internal and outer sheath.
- Outer sheath: Synthetic thermosetting compound type 5GM5 to DIN VDE 0207 Part 21.
