  Characteristics Features and Technical Parameters
  ① Rated voltage Uo /U: 0.6/1KV.
  ② The highest long-term allowable working temperature for the cable’s conductor:
  It is 90℃ for XLPE insulated cables while 70℃ for PVC insulated ones.
  ③ The highest allowable temperature for cable’s short circuit (the longest duration of no more than 5 seconds):
It is supposed to be no more than 250℃ for XLPE insulated cables while the maximum allowable for PVC insulated ones is 160℃.
  ④ The ambient temperature should not be less than 0 ℃ while laying the cable. When it is below 0℃, it should be pre-heated in advance. As to the allowable bending radius of the cable, it should be no less than 20 times of the outer diameter of the cable for the single-core ones while no less than 15 times of the cables’ outer diameter for multi-core ones.
  ⑤ The finished cable is supposed to withstand the 3500V power frequency voltage test for continuous 5 minutes without breaking down.
  ⑥ The conductor’s DC resistance at 20℃ is in compliance with the specific standard entitled GB3956.
  ⑦ The Cable has a lower and uniform positive ( inverse ) and zero sequence work impedance, which contributes to its improvement of the quality of power supply greatly.
  ⑧ Under the zero-sequence working condition, the reactance of the concentric layers of conductors is much lower than the fourth core of four-core cable in most cases, which can mean great help to the sensitive action of the automatic short -circuit protection device, thus ensuring the safe operation of the cable -related equipment.
  ⑨ It is strongly resistant to electromagnetic interference, lightning and other disturbance.
  ⑩ Combustion Characteristics of the Cable:
  The flame-retardant cable should be able to withstand the bunched burning test in accordance with the standard entitled GBl2666.5 (1EC332-3) while the fire-resistant ones should be able to withstand the required fire resistance test entitled GBl2666.6 1EC331).
