With this all-round   support the  DONGFENG   cables   HV-team will be at our   customer's service in regard of the products   high voltage and extra   high voltage cables   and accessories. Optimized internal communication   systems, specialized divisions   and intensively trained team members are   the power behind the customer-orientated   installation solutions. With competence and   know-how the  DONGFENG   cables "Power Team"   provides secure and reliable power supply wherever fully developed high-voltage power   transmission is needed
Th e   DONGFENG   cables HV-team has   gained overall   international experience .   As the HV-team feels bound to   always deliver the optimal tailor-made system   solutions, no two installations are alike. And   while doing so, security and economy always   come first.

The Cables
Design and manufacture
A wide variety of high voltage cable designs   is offered   by   DONGFENG   cables to prov ide most economic   solutions. Various types of conductors,   insulation, metallic screening and sheathing,   corrosion protective layers etc. are available.
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 mm ²   (RE)
(2) circular stranded compacted conductors   up to 1200 mm ²   (RM)
(3) circular conductors with shaped wires up   to 2000 mm ²   (RM, Keystone conductors)
(4) segmental conductors up to 2500 mm ²   (RMS, Milliken conductors)
(5) oval shaped stranded compacted conductors   up to 800 mm ²   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 cabl es,   DONGFENG   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   DONGFENG   cables both, ext ruded 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.

Cabling and Armouring
For the conventional pipe type cables as   well as for the City   Cable, laying-up of the
three cores and provision of the strong steel   armour is an essential feature. Therefore,
DONGFENG  cables disposes also o f the appropriate   machinery to carry out these production
Steps.
