 Product DescriptionHigh Voltage and extra High Voltage, a speciality of the HV-teamDevelopment, 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 neededThe 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 CablesDesign and manufactureA 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.ConductorsThe cable conductors can be made of copper or aluminium. The choice is a matter ofcustomer's preference or current carrying capacity. Large size solid conductors aremade 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 gaspressure cables (OM)The conductors are manufactured to meet the requirements of the relevant national andinternational standards. For special applications the conductors can be made watertight.InsulationThe insulations for low pressure oil filled cables and for conventional pipe type cablesare lapped from high quality insulating papers. Subsequently the paper insulated cable cores are impregnated in appropriate vessels with low viscous oil or high viscouscompound.For manufacture of XLPE insulated high voltage cables, DONGFENG cables disposes of four extrusion lines. Highest quality standards together with latest process control equipmentand combined with decades of experience ensure manufacture of cables meeting the highest requirements and enabling development of most advanced power cable systems.Metallic CoveringConventional paper insulated cables require a pressure proof and watertight metallicenclosure, acting also as metallic screen. At DONGFENG cables both, extruded lead sheath aswell 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 usuallyequipped 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.OversheathAn extruded polyethylene sheath is provided as the standard solution. With respectto 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 differentsheathing material may be used, optimized for the purpose.Cabling and ArmouringFor the conventional pipe type cables as well as for the City Cable, laying-up of thethree 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 productionSteps.Product ParametersNo.of cores(mm2)Continuous current-carrying capacity (A)Fault current carrying capacity for 1 secondIn airIn groundSolid bondSolid bondSolid bondSolid bondCond.(kA)Scr.(kA)1x15046648935934121.516.51x18548550542040526.516.51x24056559048046534.316.51x30064568555053542.916.51x40074577564561057.216.51x50084589570069071.516.51x630970102079078090.116.51x8001100116588087011416.51x10001280135010098014316.51x1200140014801080105517216.51x1600164417261177111822916.51x2000183119221249118628616.51x25002428254914471374357.516.5No. of cores(mm2)Conductordiameter(mm)Insulationthickness(mm)Diameterover insluation(mm)Approx.screen area(mm)Nominalthicknessof APL/HDPE sheath(mm)Overalldiameter
