Aluminum Armoured High Voltage Cable 220kv 1c2500sqmm XlPE Insulated Corrugated
Brief introduction of the 110~220KV XLPE high-voltage cable products
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.
- Cable`s conductor highest working temperature is allowed up to 90℃, and overload when meet an emergency is 130℃ ,When short circuit (in ≤5 seconds) the highest temperature is 250℃
- When installing or laying cable, the ambient temperature should be less than -20℃, and have to give a preheat to cable.
- The minimum bendind
Note: In form, D0 is a real test value to cable`s outer diameter.
- Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent section) T=K×core NO. ×section (kg), in formula, the coefficient K value should be: the copper core get 7, the aluminum core get 4.
- 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.
- Cable laying is not being restricted by drop.
- The structure parameter and functions table to 110KV, 220KV XLPE high-voltage cable products
- Rated voltage 64/110KV XLPE copper core and PE insulated wrinkled aluminum wrapper waterproof layer PE(or PVC) sheathed power cable.
Note: Current carrier capacity is made up by laying in soil abreast. The axial distances between cables are 200mm. Soil temperature is 25℃. The working temperature of cable is 90℃. The coefficient of soil heat-resistance is 1.2km/W.
- Rated voltage 127/220KV XLPE copper core and PE insulated wrinkled aluminum wrapper waterproof layer PVC (or PE) sheathed power cable.
Note: Current carrier capacity is made up by laying in soil abreast. The axial distance between cables are 200mm. Soil temperature is 25℃. The working temperature of cable is 90℃. The coefficient of soil heat-resistance is 1.2km/W.
