2. No. of core: Single core or three cores.
3. The highest allowed operating temperature of conductor for long-term working is 90oC. In short-circuit (Max. long-term is no more than 5 seconds). The highest temperature for conductor is no more than 250ºC.
4. D.C. resistance of the conductor complies with the stipulations of 3.6/6kV, 6/10kV(11kV), 12/20kV(24kV), 19/33kV, 26/35kV(35kV).
5. The environment temperature should be no lower than 0oC when lay. Otherwise it should be preheated.
6. The cable is laid without horizontal drop limit.
7. Working Frequency Voltage Test: 3.5Uo/5min without puncture.
8. Partial Discharge Test: The discharge volume should be no more than 10pC under 1.73Uo for the cable.
9. Minimum Bending Radius:Single core – Fixed: 15 x overall diameter;3 core – Fixed: 12 x overall diameter
(Single core 12 x overall diameter and 3 core 10 x overall diameter where bands are positioned adjacent to joint or terminations provided that the bending is carefully controlled by the use of a former)
Note:The single core armoured cables are used for D.C. system only. If used for A.C. system, the magnetic isolation should be applied on the steel armor wires of non-magnetical materials should be used.
