Product Description

 

Product Description

1.   Main Application
    XLPE(Cross linked polyethylene) cable constitutes the best cable for transmission and distribution lines because of its excellent electrical and physical properties. These cables has the advantage of simplicity in construction, lightness in weight; convenience in application besides its excellent electrical, thermal, mechanical and anti-chemical corrosion properties. It can also be laid with no limitation of level difference along the route.

2.   Standards
    GB/12706.2, IEC60502-2,BS 6622 , VDE 0276, HD 620 S1,NFC 33-226, IS 1554 , IS 7098 and ICEA S-66-524 etc.
* Xinfeng Cable can also design and produce for special application requirement.

3.   Product PropertiesThe product is suitable for power transmission and distribution lines with rated power frequency voltage 6kV~35 kV.
3.1 Rated voltages U0/U(Um): 3.6/6(7.2)kV,6/10(12) kV, 8.7/15(17.5) kV, 12/20(24) kV, 18/30(36) kV; 21/35(40.5) kV; 26/35(40.5) kV;
Note: The above rated voltages are equivalent to 3.8/6.6(7.2)kV,6.35/11(12) kV, 8.7/15(17.5) kV, 12.7/22(24) kV, 19/33(36) kV;
U0 :Rated power-frequency voltage between conductor and earth or armour, metal sheath or screen for which the cable is suitable.
U :Rated power-frequency voltage between phase conductors for which the cable is suitable.
Um :Maximum value of the highest system voltage between phase conductors for which the cable is suitable.

3.2 The ambient temperature for installation: ≥0ºC
3.3 Maximum conductor temperature in normal operation:≤90ºC
3.4 Max operating temperature of con. When cable short-circuited(5s maximum duration): 250ºC
3.5 Permissible minimum bending radius:
Single unarmoured cable: 20 x OD
Multi-core unarmoured cable: 15 x OD
Single armoured cable: 5 x OD
Multi-core armoured cable: 12 x OD
Note : OD=Overall Diameter of Cable
