10 kV Aerial Insulated Cables Standards Implemented
This product is produced according
the national standard GB/T14049-2008, applicable to the AC rated voltage U (Um) of 10 (12) kV for overhead power line steel core, aluminum core cross-linked polyethylene or high-density polyethylene insulated aerial cable.
10 kV Aerial Insulated Cables Using Feature
Maximum long-term allowable operating temperature of the cable conductor (with load bearing structure cable)
1. Cross-linked polyethylene insulation 90℃;
2. High-density polyethylene insulation 75℃. In case of a short circuit (maximum duration not exceeding 5 seconds) the maximum temperature of the cable should not exceed:
(1). Cross-linked polyethylene insulation 250℃;
(2). High-density polyethylene insulation 150℃. The laying temperature of the cable shall not be lower than -20℃; the allowable bending radius of the cable shall not be less than the diameter of the cylinder used in the cable bending test.
Type and Designation
| Type | Product Designation | Main application |
| JKYJ | Cu core XLPE aerial insulated cable | Overhead fixed laying, soft copper core products for the transformer lead, cable erection, should be considered to maintain a certain distance with the trees, the cable is running, allowing the cables contact with trees frequently. |
| JKTRYJ | Soft Cu core XLPE aerial insulated cable | |
| JKLYJ | Al core XLPE aerial insulated cable | |
| JKY | Cu core PE aerial insulated cable | |
