Rated voltage 10kV 35kV overhead insulated cables

  Standards and Scope
  This product is manufactured in accordance with the general industry standard entitled GB14049-93 and it is suitable for dense polyethylene overhead insulated cables as well as the copper-cored or aluminum-cored crosslinked polyethylene overhead power lines with the AC rated voltage at U (Um) to 10 (12) KV, 35 (42) kV.

  Characteristic Features
  The highest long-term allowable working temperature for the cable’s conductor: (cables with load-bearing structure)
  1. It is 90℃ for XLPE insulated cables.
  2. It is 75℃ for dense polyethylene insulated ones.
The highest allowable temperature for cable’s short circuit (the longest duration of no more than 5 seconds)
  1. It is supposed to be no more than 250℃ for XLPE insulated cables.
  2. As for the dense polyethylene insulated ones, the maximum allowable is 150℃.
  Moreover, the temperature while laying cables is supposed to be no lower than -20℃ while the minimum bending radius of the cable should be no less than the diameter of the cylinder used in the cable’s bending test.

  Notes
  ( 1 ). K stands for the load-bearing stranded wire while any required cross-sectional area in Table 2 can match the cross-sectional area of its corresponding conductor according to the design requirements of the project. 
  (2). The capital letter (A) here means it’s a steel-loaded stranded wire. Similarly, the (B) means it’s an aluminum alloy-loaded stranded wire.
