JKLYJ overhead cable 10KV

1. Use: Suitable for overhead power lines with AC rated voltage of 35KV and below, and used in towns, high-rise buildings and forest areas with high safety requirements.

2, using features:

①The rated voltage is 1,10KV.

②The long-term working temperature of the cable:

Polyvinyl chloride (PVC), polyethylene (PE) insulation should not exceed 70 degrees Celsius;

Cross-linked polyethylene (XLPE) insulation should not exceed 90 degrees Celsius.

③ The maximum temperature of the cable conductor during short circuit (the longest duration does not exceed 5 seconds);

PVC insulation does not exceed 160 degrees Celsius;

Polyethylene insulation does not exceed 150 degrees Celsius;

XLPE insulation does not exceed 250 degrees Celsius.

④The temperature of cable laying should not be lower than -20 degrees Celsius.

3, technical performance:

①The conductor should be a compressed round stranded wire, and its maximum resistance and minimum breaking force should meet the requirements in Table 3.

② The breaking force of the load-bearing stranded wire shall comply with the provisions of Table 10.

③The insulation should be made of black weather-resistant polyvinyl chloride, polyethylene and cross-linked polyethylene.

④The cable should be able to withstand the specified AC voltage test for 1 minute, and the insulation should not break down.

⑤The 10KV cable with insulation shield should be subjected to partial discharge test, and its discharge should not exceed 20PC.

4, Delivery requirements:

The delivery length is determined by negotiation between the supplier and the buyer.

The length measurement error should not exceed ±0.5%.

5, Storage and transportation instructions:

Cable ends should be sealed against water and avoid open storage.

The cable reel is not allowed to be laid flat or dropped from a high place to prevent mechanical damage to the cable. Prevent mutual collision or overturning.
