Note: The aluminum conductor is not recommended concerning to cables for voltage exceeding 220kV.
- The property of cable conductor is in accordance with the rules of GB/t 3956-2008. The cross-section below 800mm2 should be tight round winding conductor; above 1000mm2 should be segmentation conductor construction.
- Inner shield adopt the cross-linked semi-conductive shield materials to extrude over the conduct extremely smoothly.
- Insulation should adopt the extremely clean XLPE insulation materials, and triple extrude with outer shield tightly bonded.
- Outer shield should adopt cross-linked shield materials o extrude over insulation extremely smooth.
- Vertical water blocking layer and buffer layer should adopt semi-conductive water-proof tapes with strong capacity of water-proof to wrap between the outer shields and vertical water-proof layer.
- Vertical water-proof layer should adopt the al-plastic composites and iron jack should adopt corrugated aluminum or lead sheath, which can meet the capacity and screen of short circuit.
- Protection layer and corrosion resistance layer make sure the effective protection for the corrugated aluminum jack or lead sheath.
- Outer jack should adopt PVC, PE or other relative sheath materials to extrude, in order to meet the electrical function and mechanical function. Other types of cables such as flame resistance, rat proof, low smoke and halogen also are produce as the different requirements of different places. The surface of outer sheath coasts or extrudes with a layer of continuously smooth semi-conductive materials as the pressure-resistant electrode of outer sheath.
