Standards Implemented of 35 kV Aerial Insulated Cables
This product is produced according to the national standard GB/T14049-2008, applicable to the AC rated voltage U (Um) of 35 (42) kV for overhead power line steel core, aluminum core cross-linked polyethylene or high-density polyethylene insulated aerial cable.
Using Feature of 35 kV Aerial Insulated Cables
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 of 35 kV Aerial Insulated Cables
| 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 | |
| JKTRY | Soft Cu core PE aerial insulated cable | |
| JKLY | Al core PE aerial insulated cable | |
| JKLYJ/B | Al core with essential color XLPE aerial insulated cable | as above |
| JKLYJ/Q | Al core light XLPE aerial insulated cable | When the cable is erected, it should be considered to maintain a certain distance from the trees. When the cable runs, only short-term contact between the cable and the tree is allowed. |
| JKLY/Q | Al core light PE aerial thin insulated cable |
