Product Description

High Voltage and extra High Voltage, a speciality of the HV-team
Development, consultancy, planning and design, cost-optimization, production, logistics, installation and service. 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
The 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 provide 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 the 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, 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.

Water-blocking design
1. The conductor mostly uses a compact circular structure. For if copper conduct normal cross-section is in range of 800 mm2 and above, and the aluminium conductor in the range of 1000mm2 and above the structure should be Milliken conductor. We can achieve the conductor longitudinal water-blocking request.
2.  Products in all types and sizes have longitudinal water-blocking layers which are made up of semi-conductive water-proof cushion tape wrapped between the outer screen and radial water-blocking layer.
3. Aluminium-plastic sheath/swelling layer for vertical water resistant
4. Aluminium-plastic tape or corrugated aluminium sheath can be taken as a radial water-resistant layer, Corrugated aluminium sheath can be also taken as the metal screen sheath.
5. For laying in tunnel or duct, used in a damp environment or the place where the water level is comparatively high and able to bear moderate pressure

Metallic Covering
Conventional paper insulated cables require a pressure proof and watertight metallic enclosure, acting also as metallic screen. At DONGFENG 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.

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 of the appropriate machinery to carry out these production Steps.
