Some models of overhead cables

 ^{Technical Parameters Of Overhead Insulated Cable
1.Weather resistance
High electrical performance, good weather resistance, can work safely under long-term sunlight
2.Insulation level
The ground voltage of the overhead cable is shared by the main insulation and the air medium, and the insulation performance is higher, which is better than that of ordinary ordinary oil paper and cross-linked cables.
3.Inner and outer semi-conductive shielding layer
1KV low-voltage overhead cable, the surface electric field strength is very low, do not need to use the inner semi-conductive shield.When the overhead cable is close to the grounding body, the electric field strength on the surface of the conductor of the 10kV overhead cable is 2 ~ 3kV / mm, and the electric field strength on the surface of the conductor of the 35kV overhead cable can be as high as about 5kV / mm, and the inner semi-conductive shielding layer is needed.}

 ^{Application of XLPE Insulated Cable
1.Overhead insulated cables with a rated voltage of 1kV and below are suitable for overhead power lines with a rated voltage of 0.6% 2F1KV and below, and can be used as fixed laying or household wires.
2.Overhead insulated cables with a rated voltage of 10kV and below are suitable for overhead power transmission line transmission.10kV transmission lines for power grid construction and transformation are preferred.
3.Steel core aluminum stranded wire core overhead insulated cables with rated voltage of 10kV and below are suitable for overhead power distribution lines with AC rated voltage of 10kV and below.}

 ^{Product Advantages
1.High reliability of power supply
Overhead cables can greatly reduce all kinds of short-circuit faults.Compared with overhead bare conductors, the failure rate is 4-6 times lower.
2.Good power supply security
Overhead cables greatly reduce the risk of personal injury from electric shock
3.Convenient erection and maintenance
The overhead cable can be erected on any kind of pole tower or along the wall.In special cases, it can also be traversed through the trees and directly fixed on the pole with metal fittings.
Overhead cables do not need to be subject to special patrol inspections, nor will short-circuit trip accidents be formed due to flashover of branches, littering by residents, or accidental collision of crane booms, which greatly reduces the maintenance and repair work of the line.
4.Reasonable economy
Lower overall cost, more economical and more reasonable}
