High Voltage XLPE Insulation Cables

Standard: IEC60840, IEC62067<br />Type: YJLW02 (YJLLW02)<br />Name: Copper(aluminum) conductor, XLPE insulation, corrugated aluminum sheath, PVC outer sheathed power cable<br />Rated Voltage: 66~500kV<br />Nominal section: 150~2500 mm2<br />The cables can bear a bigger pulling force and pressure, suitable for placing underground, with water level not very high, in tunnels or pipes, etc.<br />u2022 Conductor<br />- Copper (Cu) or Aluminum (Al) stranded compacted<br />conductor or<br />- Cu segmented conductor or<br />- Cu or Al conductor with key-stone shaped profiles<br />- Longitudinal water sealing of conductor<br />u2022 Insulation and Screen<br />VCV line introduced from Nokia:<br />Triple extrusion (inner conducting shield, insulation and outer conducting shield processed in one sealed operation)<br />and dry vulcanisation (no water or steam during vulcanisation) together with improved material cleanliness and handling systems.<br />u2022 Semi-conductive Waterproof Cushion Layer<br />Imported top-quality semi-conductive waterproof swelling tapes are wrapped<br />on insulated core as longitudinal waterproof cushion layer.<br />Suitable wrapping method results in completely effective and excellent longitudinal<br />waterproof along cable screen.<br />u2022 Metallic Sheath<br />Corrugated aluminum sheath not only satisfies the short circuit<br />capacity, but also has an excellent strength, low weight, bending easily and good waterproof performance.<br />u2022 Oversheath<br />Oversheath is extruded with PE or PVC compound, also anti-termite compound as per the customer's requirements. Semi-conductive coating is applied as an electrode of oversheath for withstand voltage test.<br /> Other information, please feel free to contact me: tbcable(at)yahoo dot cn.<br/><h2>Product Feature</h2><br/>Key Technology of HV Cable<br />Insulation free from impurity and micropore;<br />Smooth Interface;<br />Insulation Stress Relief.<br />Performance:<br />1. Cable' s conductor highest working temprature should be max.90?, and overload when meeting an emergency is 130?; at shortcuit (during less than 5s, ) max.250?. <br />2. When installing or laying the cable, the ambient temperature should be no less than 0?. <br />3. Allowed max. pulling force to condutor: Cu cable:70N/mm2, Al cable:40N/mm2;the minimum bending radius is 20D; allowed biggest lateral pressure max.5 kN/m. <br />4. Cable laying is not restricted by drop.
