1KV/10KV Insulated Overhead Cable
Power Cables/ Overhead Line/ Insulated Power Cable
The 1KV, 10KV insulated overhead cable is used for AC rated voltage in 1/10KV power distribution line systems.
Product Characteristics
1. Operational performances
1) Rated voltage 0.6/1KV, 10KV
2) Allowable long-term working temperature of conductor: PVC insulation ≤70℃, XLPE insulation ≤90℃
3) Short circuit (maximum continuous period no more than 5S) maximum temperature of cable: PVC insulation 160℃, XLPE insulation 250℃
4) Cable laying temperature≥-20℃, when temperatue is lower than -20℃, the cable should be preheated
| Rated voltage(KV) | Insulation resistance not less than MΩ/KM |
| 10(ordinary insulation) | 1500 |
| 10(light type insulation) | 1000 |
| 10(thick insulation) | 1800 |
| Model | Name | Laying condition | ||
| Copper core | Al core | steel core (reinforced Al stranded core) | ||
| JKV | JKLV (BLVW) | JKLGV(BLVWG or BLGVW) | PVC insulated overhead cable | Fixed overhead laying or used as drop wire,only used for voltage 0.6/1KV |
| JKYJ | JKLYJ | JKLGYJ | XLPE insualted overhead cable | Fixed overhead laying or used as drop wire,When laying,should consider a certain distance between cable and trees ,when the cable is working,allow cables touch trees frequently,allow low laying |
| JKYJ/Q | JKLYJ/Q | JKLGYJ/Q | XLPE insulated light type overhead cable | |
| JKYJ/J | JKLYJ/J | JKLGYJ/J | XLPE insulated thick overhead cable | |
Notes
1. 1KV insulated overhead cables are 1,2 or 4 cores with 10-400mm2 ;10KV insulated overhead cable is mainly single core, with 16-400mm2
2. Choosing steel reinforced steel core according to the tensile strength of steel reinforced Al stranded wire
