Single&Multi Phase Copper Core 18/30 Kv 20kv 25kv 33kv 35kv 36 Kv XLPE High Voltage Armoured Power Cables

The company mainly produces high-voltage cross-linked cables below 35 and 10 kV, steel wire armoured cables, aluminum alloy cables, polyvinylidene edge power cables, control cables, image sleeve cables, various mining cables, flame retardant, fire resistant, waterproof, high temperature resistant cables, overhead lines, cloth wires, low-smoke halogen-free flame retardant radiation resistant cross-linked wires, PVC cable particles, copper tape and other cable accessories; It can also design and produce wires and cables with high technical content and high technological difficulty according to the user's no demand, and can also produce products according to the standards of other countries.

1. Rated voltage: Uo/U:3.6/6kV, 6/10kV(11kV), 12/20kV(24kV), 19/33kV, 26/35kV(35kV).
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 a 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 a 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 armored cables are used for the D.C. system only. If used for the A.C. system, the magnetic isolation should be applied to the steel armor wires of non-magnetical materials that should be used.
