Audited Supplier The overhead insulated cable has the characteristics of large power transmission and strong mechanical strength. Compared with bare wires, it has the advantages of small laying span, high safety and reliability, and good resistance to atmospheric aging. The racks are preferentially used for urban and rural power transmission construction projects.
This product is suitable for overhead power lines and transmission and distribution lines with AC rated voltage U (Um) 10 (12) KV and below in urban high-rise buildings, tourist development zones, forest areas, etc.
JK stands for overhead
L represents the conductor is aluminum wire,
Y stands for polyethylene,
YJ stands for cross-linked polyethylene,
JKLY overhead insulated cable.
Operating temperature: the maximum long-term operating temperature of the cable conductor is 90°C
Short-circuit temperature: the maximum temperature of the cable conductor does not exceed 250 ºC during short-circuit (the longest duration does not exceed 5s)
Laying temperature: the ambient temperature when laying the cable should not be lower than 0 ºC
Bending radius: the bending radius of single-core cable is not less than 15 times the outer diameter of the cable, and the bending radius of multi-core cable is not less than 10 times the outer diameter of the cable
Scope of application: It can be laid indoors, in tunnels, cable trenches and pipes, and can also be buried in loose soil. The cable can withstand certain laying traction, but cannot withstand mechanical external force.
(1) Rated voltage of cable is 10 kV.
(2)Max. long - term permissible operating temperature of conductor:
Xlpe insulation is 90ºC
High density polyethylene insulation 75ºC
(3) When short circuit (the longest duration is not more than 5 seconds), the highest temperature of cable:
Xlpe insulation is 250ºC
High density polyethylene insulation is 150ºC.
(4) The laying temperature of cable should not be less than -- 20ºC
(5) Allowable minimum bending radius of cable:
Single core cable: 20 (D+d);
Multi-core cable: 15 (D+d);
Where: D -- actual outer diameter of cable, mm
d -- Actual outer diameter of cable conductor, mm
Product technical parameter
1. Compared with the steel core aluminum stranded wire, the insulated overhead cable has the advantages of small installation distance between cables, reduced space, and high safety factor.
2. Overhead insulated cables are mainly used in the transformation of power grids in cities and forest areas. The product is simple in structure, safe to use, and has excellent mechanical, physical and electrical properties. Excellent resistance to tracking, surface discharge and atmospheric resistance. At the same time, when the overhead cable is used for long-distance power transmission in the suburbs, the cable inductance value is very low, and the line voltage drop is small. Do not increase the boosting measures, which has high economic benefits.
