National standard JLB20A-50 JLB20A aluminum clad steel stranded wire OPPC composite overhead phase line

Description :

　　 National standard JLB20A-50 JLB20A aluminum clad steel stranded OPPC optical cable

　　Application of aluminum clad steel stranded wire:

　　 Mainly used as overhead ground wire to prevent lightning.

　　Characteristics: Due to the development of production technology for aluminum clad steel wire, aluminum clad steel wire has superior performance. Its characteristics are as follows: 1. The size and performance of aluminum clad steel wire can be adjusted within a large range (product size range of 1.2 mm to 0.10 mm, product strength range of 50MPa to 1400 MPa), the adjustment range of the ratio of aluminum layer to wire cross-sectional area can reach 13% to 85%, and the conductivity range is 14% to 55% IACS.

　　The aluminum layer on the surface provides excellent corrosion resistance.

　　3. The bonding strength between aluminum and steel is good. ­

　　4. The density is lower than that of galvanized steel strands and aluminum coated steel strands.

　　When used as a power transmission line, it has excellent heat resistance.

　　6. The cross-section of the wire can be made into complex shapes.

　　Aluminum clad steel stranded wire: Concentric stranded wire made of cold drawn circular aluminum clad steel wire.

　　Aluminum clad steel wire: a circular wire consisting of a round steel core wrapped in a uniform and continuous layer of aluminum.

　　Types of Aluminum Clad Steel Stranded Wire

　　The representation method of aluminum clad steel stranded wire: J+single wire grade - nominal cross-sectional area of aluminum clad steel stranded wire, for example JLB20A-50, the letter J represents concentric stranded wire, LB represents single wire grade of aluminum clad steel wire, and 50 represents nominal cross-sectional area of 80mm2. Aluminum clad steel stranded wire model JLB20A, specifications 30-800, in accordance with standard GB/T124-2017.
