3. AC voltage test
Finished cable shall pass the AC voltage (50Hz、5min、3500V) test without breakdown. Water-immersion voltage resistant test is for the single core cable with no armor.
4. Flame-retardant test
Finished cable shall meet the flame-retardant property test requirement stipulated in IE60332-3 and GB/T18380.3.
5. Fire-resistance test
Finished cable shall meet the fire resistant test requirements stipulate d in IEC60332-21 and GB/T19216.21.
Ⅵ. Feature
1. It has excellent electricity property and thermal resistant property.
2. For adopting color identification for the insulation cores, its unbalance phenomenon of the insulation resistance decrease dramatically.
3. There is no limited at height drop for installation .
4. Five-core power cable is suitable to use in three-phase five-wire transmission and distribution power system. Separating the neutral wire from the ground wire thus is available for the stable operation of the system and safety of the operator. Moreover, s] nce the five-core power cable is designed in a special tile form, the cable has many features such as a stable structure, lightweight, small outer diameter and so on.
