Bus Route: take Bus 3, 15, 135,291, 357, 516 to junction between Baizhang East Road and Zhongxing Road;
                     Bus 507, 512, 522, 526 to Scientific Technology Station.

Application:  

It consists of copper aluminum (AL alloy) conductor, inner shielding layer, weather-proof insulation material and outer shielding layer. It has not only power-transmitting character of power cable, but strong mechanical character of aerial cable as well. In comparison with bare wire, it boasts many advantages such as small span in laying the cable, high reliability and safety, and good aging-resistant character. It is the first priority of newly designed and built power-transmitting project of 10kv or lower.

Description:

Executive Standard:          
   1kv Aerial Insulation Cable: GB12527-90(with reference to IEC60502, IEC227);    
   10kv Aerial Insulation Cable: GB14049-93
        
Working Conditions:          
   1．Rated Voltage:1kv,10kv;         
   2. Long-term working temperature allowance of the cable: with PVC insulation:70℃;with XLPE insulation:90℃;      
   3．The highest temperature of the cable in time of short circuit: with PVC insulation:160℃; with HDPE insulation: 150℃;with XLPE insulation: 250℃         
   4．Environment temperature should be no lower than-20℃ for laying the cable        
   5．Bending radius allowance of the cable:         
       ①．For cable of rated voltage under 1kv: 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;         
  　 ②．For cable of rated voltage 10kv: Single core cable:20(D+d) ±5%mm;multi-core cable:15(D+d) ±5%mm. In the formula above: D—actual cable outer diameter; d—actual conductor outer diameter.
