20kv cable single core cable 300mm

20kv cable single core cable 300mm 

Cable conductor allows a maximum operating temperature of 90 ℃, emergency overload maximum operating temperature of 130 ℃ note, when a short circuit ( time ≤ 5 seconds) conductor maximum temperature of 250 ℃.

Note : China's power sector is no uniform overload time specified ; American standards , the load exceeds 10% of the rated load , duration of not more than 15 minutes .
Laying of cable installation when the ambient temperature is not lower than -20 ℃, warm-up time to deal with the cable laying .

Cable minimum bending diameter:

1. XLPE insulated wrinkled aluminum wrapper waterproof PVC sheathed power cable

2. XLPE insulated and wrinkled aluminum wrapper waterproof layer PE sheathed power cable

3. XLPE insulated PVC sheathed power cable lead pack

4. XLPE insulated PE sheathed power cable lead pack

Cable Type

Note: The table D0 measured value for the cable diameter .
    The maximum allowable axial traction ( not considering the turn of the radial side pressure ) when the cable is installed
    T = K * cores * cross-section (kg)
    Where the coefficient K value , taking seven copper or aluminum conductor to take 4 .
    When the maximum permissible cable bend side pressure P
    Single core cables required P ≤ 500kg / m.
    P = T / R (T axial traction , R is the radius of the bending wheel )
    Because traction is generally determined by the above equation by the cable length and weight , to make P meet the above requirements , should increase the turning wheel diameter .
    Cabling not drop restrictions .
