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=K� Core NO. � 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 P� 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. http://www.alibaba.com/product-detail/240mm-300mm-400mm-500mm-630mm-800mm_60455062615.html?spm=a271v.8028081.0.0.ziQH7w
