Product Description:
-
The long-term permissible operating temperature of the cable conductor shall not exceed 90℃. In case of short circuit (the maximum duration shall not exceed 5 seconds), the maximum temperature of the cable conductor shall not exceed 180℃.
-
The ambient temperature during cable installation should not be lower than 0℃. If it is below 0℃, preheating should be carried out first. The minimum bending radius shall not be less than the cable outer diameter: for single-core cables, it is 20 times for those without armor and 15 times for those with armor; for three-core cables, it is 15 times for those without armor and 12 times for those with armor.
-
The DC resistance of the conductor shall comply with the provisions of GB/T 3956.
-
Power frequency withstand voltage test: no breakdown at 3.5 kV for 5 minutes.
