0.6/1kV XLPE Insulated Overhead Cable(JKYJ/JKLYJ)


0.6/1kV XLPE Insulated Overhead Cable(JKYJ/JKLYJ)
Standard: IEC502, IEC227 standard and other
Capacity: 2000km/m
Voltage: 0.6/1kV
Application: fixed installation, during erection should keep a certain distance between the cable and trees, and trees allow frequent contact cables during cable operation.
   


0.6/1kV copper/aluminum core XLPE insulated overhead cable (JKYJ/JKLYJ)
The product is composed of tight conductor, weather resistant insulation and corresponding semi conductive shield, which has the mechanical property of the overhead line, and the safety transmission characteristic of the power cable. Compared with the bare wire, has small spacing erection, high safety and reliability, ageing resistance and other excellent performance characteristics, is preferred by varieties of city and town cable transmission engineering.
 
Cable standard:
 
GB12527-90 1kV overhead insulated cable (refer to the international IEC502, IEC227 standard);
 
CB14049-93 10kV insulated overhead cable.
 
Characteristics of overhead insulated power cable:
 
1) rated voltage: 1kV, 10kV.
 
2) the maximum operating temperature of the cable conductor:
Cross linked polyethylene insulation:90℃
High density polyethylene insulation: 75℃
 
3) the maximum temperature of the cable conductor (the longest duration does not exceed 5S):
Cross linked polyethylene insulation 250℃;
High density polyethylene insulation 150℃;
 
4) the ambient temperature should not be less than -20℃;
 
5) Allowable bending radius of cable:
 
A, 1kV overhead insulated cables:
Cable diameter less than 25mm should be not less than 4D;
The cable diameter larger than 25mm and above shall be not less than 6D;
 
B, 10kV overhead insulated cables:
Single core cable: 20 (D+d) + 5%mm;
Multi core cable: 15 (D+d) + 5%mm;
Among them: D is the actual diameter of the cable.
d is the actual diameter of the cable conductor.
XLPE insulated overhead cable
Usage:
 
XLPE insulated overhead cable is suitable for fixed installation, during erection should keep a certain distance between the cable and trees, and trees allow frequent contact cables during cable operation.
