Scope of application
Description
Overhead transmission line
Overhead fixed laying and access lines
Product Characteristics
The overhead insulated cable has the advantages of simple structure, safety and reliability, excellent mechanical and physical properties and electrical properties, environmental resistance and ultraviolet resistance, etc., because its insulation is weather-resistant special overhead insulated cable material, the long-term allowable working temperature of the cable is as high as 70ºC or 90ºC, and the electrical insulation performance is excellent, and the volume resistivity is more than 1.0×10^12Ω·m; In laying, the overhead insulated cable can reduce the laying gap, save the line corridor and reduce the voltage drop. In use, it can reduce the occurrence of power supply accidents and ensure personal safety.
The standard
Executive standard
GB/T 12527-2008 Overhead insulated cable with rated voltage of 1kV and below
Using features
Rated voltage
The rated voltage is 1kV
Operating temperature
The maximum allowable long-term operating temperature of the conductor is 70ºC.
Laying temperature
The laying temperature of the cable should not be lower than -20ºC.
Bending radius
For cables with outer diameter (D) less than 25mm, the bending radius is not less than 4D. For cables with outer diameter (D) greater than or equal to 25mm, the bending radius is not less than 6D.
