comply withThe provisions of GB3956

lay

When laying, the ambient temperature should not be lower thanAt 0 ℃, the small bending radius should not be less than 15 times the outer diameter of the cable.

Power frequency withstand voltage test

Cables with Uo of 3.6kV and below: 2.5Uo+2kV/5min no breakdown

Cable with Uo above 3.6kV: 2.5Uo/5min without breakdown

Partial discharge test

When Uo is 1.8kV or above and below 18kV,

The discharge power of 1.5Uo shall not exceed 20pC;

Uo is above 18kV,

The discharge power of 1.5Uo should not exceed 10pC.

Flame retardant properties

Can withstand itThe bundled combustion test specified in GB12666.5 (IEC332-3); The smoke concentration during the combustion of low smoke, low halogen, and low smoke halogen-free flame-retardant cables should comply with the provisions of GB12666.7 (IEC1034).
