127/220KV Copper Conductor, XLPE insulation Corrugated Aluminum Metalic Sheath and HDPE Sheath EHV Cable
 

High Voltage Power Cable 110~220KV Australia Standard Cable

Brief introduction of the 110~220KV XLPE  High Voltage XLPE Insulated  Australia Standard 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.

Specific property for usage of 110KV~220KV XLPE High Voltage  Australia Standard Cable :

1. Cable’s conductor highest working temperature is allowed up to 90°C, and overload when meet an emergency is 130°C , When short circuit (in ≤5 seconds) the highest temperature is 250°C

2. When installing or laying cable, the ambient temperature should be less than -20°C, and have to give a preheat to cable.

3. The minimum bending diameter:

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.

6. Cable laying is not being restricted by drop.
