APPLICATIONS

N2XH-O B2ca 0,6/1 kV and N2XH-J B2ca 0,6/1 kV power cables are designed for electric power transmission. They are also applied in control, protection and monitoring systems in power engineering.

The cables are suitable for industrial applications, such as production plants or air-conditioning systems operating in dry and wet locations, also for outdoor installations. Cables can be laid in concrete. Laying cables in water or direct earth burial is only permitted if additional protection is used.

Halogen free cables shall be applied in locations where, in case of fire, higher safety for human beings and expensive electronic equipment is required. The cables are flame retardant and their smoke emission is low, emitted fumes are non toxic and non corrosive.

CONSTRUCTION                                                                                                           

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

              RE - class 1 circular single-wire,

              RM - class 2 circular multi-wire.

- cross-linked polyethylene (XLPE) insulation, colours:

              in accordance with PN-HD 308 standard,

              or black and white conductor number printed on it;

              green-yellow protective conductor in the outer layer in N2XH-J B2ca 0,6/1 kV cable,

- insulated conductors laid-up into a cable core,

- inner covering made of halogen free compound (HFFR),

- cable sheath made of halogen free compound (HFFR), black, other colours also available.
