1) Standards
The cable meets the standard requirements of GB14049-93 or Q/SX109-2002.
Cu or Al conductor XLPE or HDPE insulated aerial cable is suitable for aerial power lines with A.C. rated voltage U (Um) up to 10 (12) kV and 35 (42) kV.
2) Type, Designation and Applications
Type |
|
|
| JKTRYJ | Soft Cu conductor XLPE insulated aerial cables |
The cables are used for aerial fixed installation. The Soft Cu conductor cable is used as lead of transformers. It should be considered to keep a certain distance between cables and trees during installation. Frequent touch between cables and trees is allowable during operation. |
| JKLYJ JKLGYJ |
Al(ACSR) conductor XLPE insulated aerial cables |
|
| JKTRY | Soft Cu conductor PE insulated aerial cables |
|
| JKLY JKLGY |
Al(ACSR) conductor PE insulated aerial cables |
|
| JKLYJ/Q JKLGYJ/Q |
Al(ACSR) conductor light-duty thin XLPE insulated aerial cables |
The cables are used for aerial fixed installation. It should be considered to keep a certain distance between cables and trees during installation. Touch, between cables and trees, is allowable only for short time during operation. |
