　　 JKLGYJ-35KV overhead insulated conductor overhead cable: also known as overhead line; Overhead power lines; Overhead insulated line; Overhead insulated conductor; Overhead insulated cables.

　　There are high and low voltage classifications for overhead cables: 1KV, 10KV, and 35KV

　　Main models of overhead cables: JKLYJ; JKLGYJ，JKLYJ aluminum core cross-linked polyethylene insulated overhead cable.

　　35KV belongs to ultra-high voltage overhead insulated conductors.

　　Insulation resistance of cables:

　　 The insulation resistance of overhead insulated cables with a rated voltage of 1KV is shown in the table below. Finished cables without insulation shielding for 10KV and 35KV should be immersed in water for no less than 1 hour and subjected to a direct current voltage of 80-500V. The stabilization time should be no less than 1 minute and no more than 5 minutes. The insulation resistance of a 10KV rated voltage cable should not be less than 1500M Ω KM， The insulation resistance of lightweight thin insulation structure cables should not be less than 1000M Ω KM. The insulation resistance of cables with a rated voltage of 35KV should not be less than 4100M Ω KM。

　　AC voltage test of cables

　　Overhead insulated cables with two or more cores and a rated voltage of 1KV should undergo a voltage test of 3500V for 1 minute. The single core cable should not break through after being immersed in room temperature water (additional electrode) for 1 hour. The rated voltage 10kV overhead insulated cable is immersed in water for 1 hour at room temperature and then subjected to voltage. The ordinary insulation structure is 18kV, the lightweight thin insulation structure is 12kV, and the 35kV is 63kV. The experimental time is 1 minute, and the cable should not break down.

　　 35kV strip steel core overhead insulated line, 35kV all aluminum overhead insulated line - comply with standard QB/DZ2020-01-2020.
