Zhengfan corrosion-resistant aluminum clad steel stranded wire JLB20A-90-4.05 * 7 wire

Description :

　　Zhengfan corrosion-resistant aluminum clad steel stranded wire JLB20A-90-4.05 * 7 wire

　　 The code for aluminum clad steel stranded wire LBGJ20A-90 is JLB20A-90, LBGJ20A-90. Aluminum clad steel stranded wire is made by twisting a certain number of aluminum clad steel single wires.

　　Aluminum clad steel stranded wire has the advantages of good conductivity, corrosion resistance, high frequency transmission performance, and high strength of steel.

　　Purpose:

　　1. Ground wire for power transmission lines, large-span conductors

　　2. Reinforced core wire for aluminum clad steel core aluminum stranded wire

　　3. Load bearing cables for electrified railway contact systems

　　4. Lightning protection grounding wire, lightning protection wire

　　5. Ice and snow resistant wire, double capacity wire, self damping wire

　　Structure: 1 × 3, 1 × 7, 1 × 19, 1 × 37, 1 × 61

　　Specification: 16mm2~670mm 2

　　Heavier than the market: 25t (￠ 3150 closing plate)

　　Technical standards: GB/T 1179-2008, TB/T 2938-1998, YB/T 124-1997, Q/AE 004-2012, ASTM B416 GB17937-1999

　　Aluminum clad steel stranded wire JLB20A-50 grounding wire and lightning protection wire. Aluminum clad steel stranded wire is divided into six groups according to conductivity: 20AC, 23AC, 27AC, 30AC, 3 * * C, and 40AC, with corresponding conductivity of 20.3%, 23%, 27%, 30%, 35%, and 40% IACS.

　　 Aluminum clad steel stranded wire, which is composed of multiple structural layers wrapped around an aluminum clad steel core layer. Each structural layer is constructed in concentric circles, with the outer layer, adjacent outer layer, adjacent inner layer, inner layer, and aluminum clad steel core layer arranged in sequence from the outside to the inside. The outer layer consists of 30 aluminum single wires, the adjacent outer layer consists of 24 aluminum single wires, the adjacent inner layer consists of 18 aluminum single wires, the inner layer consists of 12 aluminum single wires, and the aluminum clad steel core layer consists of 7 aluminum clad steel wires The product of the present invention has high strength, light weight, and small sag, which can increase the span of the iron tower or reduce the height of the iron tower, reduce land occupation and construction costs of the line. The wire connection is convenient, the construction efficiency is high, and it is not easy to wear and scratch during installation, which can reduce corona loss and reduce the interference of the transmission line on radio waves. It has good creep resistance, corrosion resistance, and long service life

　　 Aluminum clad steel stranded wire model JLB20A, specifications 30-800, in accordance with standard GB/T124-2017.
