1. The cross-linkage PE insulated and wrinkled aluminum wrapper waterproof PVC sheathed power cable.
2. The cross-linkage PE insulated and wrinkled aluminum wrapper waterproof PE sheathed power cable.
Specific property for usage of 110KV~220KV XLPE high-voltage cable
1. Cable's conductor highest working temperature is allowed up to 90º C, and overload when meet an emergency is 130º C, When short circuit (in � 5 seconds) the highest temperature is 250º C
2. When installing or laying cable, the ambient temperature should be less than -20º C, and have to give a preheat to cable.
3. The minimum bending diameter(in follow the table):
Note: In form, D0 is a real test value to cable's outer diameter.
4. Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent set ion) T=KÃ? Core NO. Ã? Section (kg), in formula, the coefficient K value should be: The copper core get 7, the aluminum core get 4.
5. Allowed biggest lateral-press P, when cable is being bent
The single core cable is required Pâ?¤ 500kg/m.
P=T/R (T is indicated axial traction force; R is indicated radius of bent-wheel), Knowing from above formula, as the traction force is made up by length and weight of cable. So it lets P to applying requirement as above. Then the diameter of bent-wheel should be widened.
