Low voltage PVC/XLPE insulation power supply cable 

Characteristics and Applications:

Low voltage PVC/XLPE insulation power supply cable has the advantages of not only high mechanical strength, good ambient stress resistance, good electrical properties and anti-chemical corrosion, but also simple construction, light weight and convenient to use. It applies to electrical power transmission and distribution lines with A.C. rated voltage U0/U up to and including 0.6/1 kilovolts.

Operating characteristics: 

(1) Rated voltage U0/U is 0.6/1 kilovolts.

(2) Maximum rated temperature of cable conductor is 90℃

(3) Maximum conductor temperature is lower than 250℃ when cable is shorted for less than 5 seconds. 

(4) Ambient temperature is not lower than 0℃ and its minimum bending radius is as follows when cable is installed: for single-core calbe-20(D+d), unit: millimeter for multi-core cable-15(D+d), unit: millimeter

Note: D denotes the overall diameter of cable, while means the nominal diameter of the main conductor, unit: millimeter.

Technical Parameter:

Calculation condition of the ampacity ambient temperature is 25℃

conductor working temperature is 90℃

soil heat resulted from water migration when it operates continuously.

gap between axis of cable and surface of ground is 1000 millimeter when it is laid in ground.  

for multi-core cable, gap of axis of cable is 3 times O.D.

Cores and sections:

1,  2,  3,   3+1,   3+2,    3+3,  4,    4+1,    4+2,   5 and so on.
