3. Operational Performance
a. Cable conductor allowed long-term working temperature not exceeding 90 ℃.
When short circuit happened (the duration no longer than 5 seconds), the maximum temperature of cable conductor is not exceeding 250℃.
b. When laying cable, the ambient temperature should not be lower than 0℃,if not the cable need to be preheated. The bending radius of three cores unarmored cable should not be less than 15 times of outer diameter of cable, 12 times for armored cable. The bending radius of single core unarmored cable should not be less than 20 times of outer diameter of the cable, 15 times for armored cable.
c. Cable DC resistance should comply with GB/T3956-1997.
d. The laying of cable is not limited by the level drops.
e. Power frequency voltage withstanding test: U0 under 3.6kV,2.5 U0+2kV/5min no breakdown.
f. Partial discharge test: discharge capacity under 1.73U0 is not more than 10 pC.
