The product is made  up of the compacted copper, aluminium(aluminum alloy) conductor,inner shield,  climate-resistant insulation material and outer shield.It has simple structure  and reliable. It has both excellent peoperties of the power cable and good  physical peoperties of the aerial cable. By using the climate-resistant  insulation material, the product has the excelent properties of resistance to  air aging. Compare with the bare wire, it has the good characteristics such as  smaller laying distance, higher reliability. It is suitable for using in the  bulidings, brushhland and bad weather zone.

Characteristics

1)       There are three rated  voltage:1kV、10kV、35kV

2)       Allowed long-term working temperature: PE  insulation--70℃, PVC insulation--70℃, XLPE insulation--90℃.

3)       When short-circuit(the longest time is not  more than5 second),the highest temperature: PE insulation--130℃, PVC insulation--160℃, XLPE insulation--250℃.

4)       The enviroment temperature for laying  should be not lower than -20℃.

5)       The working enviroment temperature is  from-40℃to +40℃, the relative humidity should be not more than 90% in rainy  season.

6)       Permitted bending  radius

Cable with rated voltage 1kV and below: outer diameter of the cable  D≤25mm,bending  radius should be not less than 4D.The outer diamter of cable D>25mm, bending  radius should be not less than 6D.

Cable with rated voltage 10kV, 35kV: single core cable:  20x(D+d)±5%

                                                            Mutiple  core cable: 15x(D+d)±5%

In which: D-the actual outer diameter of the cable,mm

               d-the actual  outer diameter of the cable conductor,mm
