Conductors
The cable conductors can be made of copper or aluminium. The choice is a matter of
customer’s preference or current carrying capacity. Large size solid conductors are
made of aluminium.
Available conductor constructions:
(1)round solid conductors up to 2000 mm2 (RE)
(2)circular stranded compacted conductors up to 1200 mm2 (RM)
(3)circular conductors with shaped wires up to 2000 mm2 (RM, Keystone conductors)
(4)segmental conductors up to 2500 mm2 (RMS, Milliken conductors)
(5)oval shaped stranded compacted conductors up to 800 mm2 for external gas
pressure cables (OM)
The conductors are manufactured to meet the requirements of the relevant national and
international standards. For special applications the conductors can be made watertight.
Insulation
The insulations for low pressure oil filled cables and for conventional pipe type cables
are lapped from high quality insulating papers. Subsequently the paper insulated cable cores are impregnated
in appropriate vessels with low viscous oil or high viscous compound.
For manufacture of XLPE insulated high voltage cables, NBF cables disposes of four extrusion lines.
Highest quality standards together with latest process control equipment and combined with decades of experience ensure manufacture of cables meeting the highest requirements
and enabling development of most advanced power cable systems.
Metallic Covering
Conventional paper insulated cables require a pressure proof and watertight metallic
enclosure, acting also as metallic screen. At NBF cables both, extruded lead sheath as
well as the aluminium sheath can be applied. These types of metal sheaths are, of course,
also used on XLPE insulated cables. While the lead sheath leads to smaller dimensions,
the aluminium sheath provides high short circuit current carrying capability and lower weight.
As the XLPE insulated cables do not require an internal overpressure, they are usually
equipped with a copper wire screen. For radial moisture barrier a coated aluminium foil is longitudinally applied.
The combination with the polyethylene oversheath is called aluminium polyethylene laminated (APL) sheath.
This solution provides high short circuit capability and watertightness combined with lowest weight and smallest
dimensions.
A combination of the copper wire screen with a metal sheath is also possible. For all XLPE insulated high
voltage cables, the space between cable core and water barrier is made longitudinally watertight.
Oversheath
An extruded polyethylene sheath is provided as the standard solution. With respect
to its excellent mechanical strength it is the optimum for buried cables. If required,
a conductive layer can be provided on the outside. For special applications different
sheathing material may be used, optimized for the purpose.
