| Model NO. | 10kV overhead insulated cable |
| Rated voltage | 10kV |
| Rated frequency | 50/60Hz |
| Series | JKLYJ |
Product use
This product is suitable for transmission and distribution lines with AC rated voltage of 10kV and below, and is used to transmit power on overhead transmission lines.
Implementation standards
This product implements GB/T 14049-2008, Q/0900 TKD001-2022, Q/0900 TKD009-2017.
Characteristics of use
The maximum long-term temperature allowed for the conductor during normal operation of the cross-linked polyethylene insulated overhead cable is 90 °C, and the maximum temperature allowed for the cable conductor is 250 °C in the event of a short circuit (the maximum duration does not exceed 5s);
The minimum allowable laying temperature of the cable is not less than -20°C;
Bending requirements for overhead insulated cables:
The minimum bending radius of single-core cable is 20 (D+d) ±5%;
The minimum bending radius of multi-core cable is 15 (D+d) ±5%.
Note: D is the actual outer diameter of the cable, and d is the actual outer diameter of the cable conductor
