Applications | These cables are used for the connection of mobile electrical equipment inunderground mines, e.g. for coal-cutting machines,especially for the use in bretby chains with extremebending loads under low tensile stress. |
Standards | VDE 0250 Part 813 |
Construction | |
Conductors | Flexible stranded tinned copper conductor. |
Insulation | Heatresistant3GI3 rubber based on EPR. |
Outer Conductor Layer (for 3.6/6kV) | Easy strippable outer conductive layer. |
