INSULATED OVERHEAD CONDUCTORS  -15KV, 25KV, 35KV

APPLICATION

 AAC. (all aluminum conductor), ACSR(aluminum conductor steel reinforced) type cable covered by XLPE, used for transmission and distribution lines in wood or industrial areas. The service voltage of all its applications varies with the thickness of the insulation, which is 15 kV, 25 kV and 35kV.

STANDARD:

 IEC 60502-2

WORKING CONDITIONS  

1)    Rated voltage: 15kV 25kV, 35kV

2)    The tallest work temperature of the cable conductor：

 XLPE insulation cable：90^oC;

3)    During having a short (lasting less than 5 seconds), the maximum temperature:

XLPE insulated cables is 250^oC;  

4)    During the cable lying, the ambient temperature must be above -20^oC.

5)    Bending radius allowance of the cable:

It should be no less than 4D for the cable with outer diameter less than 25mm;

It should be no less than 6D for the cable with outer diameter of 25mm or more.

CONSTRUCTION:

1)     Conductors
Aluminum, circular stranded and compacted confirming to IEC 60228 – Class 2

2)     Insulation
XLPE thermosetting material conforming to IEC 60502-2
