Description

Standards

  • Product
    IEC 60502-1; Nexans specification

Applications
Portable cable with extra-heavy-duty outer jacket used for power supply to all types of mobile machines in surface and underground mining, quarrying and other civil engineering operations. Thanks to the reduced diameter, Powermine® D&T installed on reeling systems allow longer travelling distance than other cables e.g. rubber sheathed cables.

 

Construction: Multicore cable with ground conductors and ground-check conductors (pilots).

1. Conductor: Very flexible stranded copper conductors, class 5 acc. to IEC 60228.

2. Insulation: Cross-linked Polyethylene (XLPE) according to IEC 60502-1.

3. Grounding conductors: One, two or three flexible copper conductors with XLPE insulation.

4. Ground-check conductor or pilots:  Upon request, could be included one or two pilots with XLPE insulation.

5. Mechanical reinforcement: Aramid yarns as a central strength member, fabric tape and double aramid servings applied over the cores asembly.

6. Jacket: Extra-heavy-duty Thermoplastic Polyurethane (TPU). Colour upon request. 

 

Marking: NEXANS CHILE POWERMINE D-T "size" 0,6/1kV  Cu XLPE 90°C "date"
