Technical Field
The utility model belongs to the technical field of the aerial [ insulated ] cable, concretely relates to parallel reinforcement type aerial [ insulated ] cable.
Background
The overhead cable (called overhead insulated cable) is an overhead conductor with insulating layer and protective sheath, and is a special cable made up by adopting the similar production process of cross-linked cable, and is a new power transmission mode between overhead conductor and underground cable. The aerial cable is a single core, and can be divided into a duralumin wire structure, an aluminum alloy wire structure, a steel core or aluminum alloy core supporting structure, a self-supporting three-core threaded structure (the wire core can be duralumin or duralumin wire) and the like according to different structures. The power supply system has the main characteristics of high power supply reliability, good power supply safety, convenience in erection and maintenance, reasonable economy and the like. The main technical parameters comprise weather resistance, insulation level, inner and outer semi-conductive shielding layers. The overhead cable has wide transmission application at home and abroad. But the common overhead cable has poor strength, resistance and insulation fire resistance, and further greatly reduces the practicability of the cable.
