PVC INSULATED AND SHEATHED POWER CABLES	Technical Data sheet

APPLICATIONS

NYY-O 0,6/1 kV and NYY-J 0,6/1 kV power cables are designed for electric power transmission. They are also applied in power circuits in industrial plants and power stations and in local distribution networks.

The cables are suitable for indoor and outdoor installations, for laying in cable ducts and for direct earth burial.

CONSTRUCTION                                                                                                          

- bare annealed copper conductors meeting requirements of PN-EN 60228 standard:

              RE - class 1 circular single-wire,

              RM - class 2 circular multi-wire,

              SM - class 2 sector shaped multi-wire,

- PVC insulation – colours:

               in accordance with PN-HD 308 standard,

               or black and white conductor number printed on it,

              green-yellow protective conductor in NYY-J 0,6/1 kV and NYY-JZ 0,6/1 kV cable,

- insulated conductors laid-up in layers,

- inner covering,

- black PVC cable sheath, other colours also available.

AVAILABLE UPON REQUEST

N2XY-O 0,6/1 kV and N2XY-J 0,6/1 kV - cross-linked polyethylene (XLPE) insulated and PVC sheathed power cables with better electric performances, smaller dimensions and weight in relation to the PVC insulated cables.

N2XH-O 0,6/1 kV and N2XH-J 0,6/1 kV - halogen free cables, applied when higher safety in case of fire is required. The cables are flame retardant, their smoke emission in fire is low and released gases are not corrosive.

Steel wire or steel tape armoured cables as above applied in locations where enhanced protection against mechanical damages is required.
