Armoured cable ratings voltage and specification
The Armoured cable is used in various fields of AC rated voltage 35kV and below  fixed line, used for power transmission and distribution, and can replace paper insulated power cable. Ordinary type products comply with GB/T12706 requirements, and consistent with the IEC60502 standard. Fire retardant products in addition to meet the above criteria, also need to comply with the GB/T18380.3 standard, and consistent with the provisions of IEC60332-3.
 
In which fire retardant armoured cable is especially suitable for power station, nuclear power plant, petrochemical, urban rail transportation, high-rise buildings and other special requirements fixed laying occasions.
 
The product is suitable for U0/U*kV 3.6/6, 6/6 (6/10), 8.7/10 (8.7/15),12/20,  18/20 (18/30), 21/35, 26/35 transmission and distribution system.
 
*U0: rated power frequency voltage between conductor and shield in cable, U: rated power frequency voltage between conductors in the armoured cable.
 
The use of characteristics:
 
1, the cable conductor is allowed to work for a long time at 90℃.
 
2, the maximum temperature of the cable conductor is no more than 250℃, the longest short-circuit time is 5 seconds.
 
3, the cable body and the environment temperature is not less than 0℃ when laying armored cable.
 
4, the cable allows the minimum bending radius: single core cable is 20 times of the cable diameter, the multicore cable is 15 times of the cable diameter.
 
5, cable laying is not limited by the difference of level.
