Application
General application as power cable. In low voltage distribution power networks, industrial installations, in buildings and operation stations. In fixed installations, indoor and outdoor areas. It can be installed in dry or wet locations; where mechanical strength is required.but it couldn't bear great pulling force. Used for power station, industry, switchgear and urban power supply network.
Standards
Basic design to IEC 60502-1, IEC 60228
China: GB/T 12706.2-2008
Other standards such as BS7870,DIN and ICEA upon request
Cable Construction:
| Conductor | The conductors shall be either of Class 1 or Class 2 of plain or metal-coated annealed copper or of plain aluminium, or of Class 5 of plain or metal-coated copper in accordance with IEC 60228. |
| Conductor Shape | Circular Stranded or Compacted Circular Stranded |
| Appearance Shape | Circular |
| Insulation | XLPE Insulation material and thickness shall be as per IEC 60502-1, rated for 90°C continuous operation. |
|
Colour Code |
3Cores: Red, Yellow, Blue |
| Assembly/Inner Covering | The inner coverings may be extruded or lapped. For cables with circular cores, a lapped inner covering shall be permitted only if the interstices between the cores are substantially filled. A suitable binder is permitted before application of an extruded inner covering. |
| Armour | Aluminum/galvanized steel/steel wires applied helically over the Inner Covering as per IEC 60502-1, or double aluminum/steel tapes and copper/tinned copper wire can also be manufactured upon request. |
| Outer Sheath | extruded Polyethylene type ST3/ST7,Cables can be supplied with special flame retardant PVC outer sheath to comply with the flame test requirements of IEC 60332-3-22, IEC 60332-3-23 and IEC 60332-3-24, Halogen Free material comply to IEC60754-1/2 and IEC 60684-2. |
Characteristics:
