　　 Aluminum clad steel stranded wire is divided into JLB14A.JLB20A, JLB27A, JLB35A, JLB40A. Its usage characteristics are suitable for all voltage levels, and the conductor is allowed to work at a temperature of 90 ℃ for a long time.

　　 Aluminum clad steel stranded wire should be delivered in reels, with the distance between the outermost layer and the edge of the cable reel side plate not less than 30mm, and properly packaged. The two twisted wires connected together during packaging should have at least half of the aluminum wire cut at the connection point, and the two sides of the connection point should be firmly tied. The cable reel shall comply with the provisions of GB4005-83 "Delivery reels for wires and cables". Short stranded wires are allowed to be delivered in loops, and each loop should be tied at least three times and properly packaged. The product should be inspected and qualified by the manufacturer before leaving the factory, and each product leaving the factory should be accompanied by a quality inspection certificate.

　　Aluminum clad steel stranded wire products:

　　1 steel strandThe diameter and allowable deviation of the inner steel wire shall comply with the specifications in Table 1.

　　2. Steel strandlay lengthIt should not exceed 14 times its diameter. Other multiples of twist length should be specified in the contract

　　3. The outer layer of the steel strand is twisted to the right. The twisting direction of the outer steel wire should be opposite to that of the adjacent inner steel wire, as shown in the following figure? If it is necessary to change the twist direction, it should be specified in the contract. Twisting of steel strand towards steel strandTwist directionIt should be left twisted (S).

　　4. When there are no special requirements? The length of steel strand shall not be less than 200m, and its length deviation is:

　　Allowable deviation of nominal length

　　<1000m +3%

　　≥1000m +1.5%

　　Aluminum clad steel wire jlb20a-50 ground wire and lightning rod aluminum containing steel wire are divided into six categories according to conductivity: 20ac, 23ac, 27ac, 30ac, 35ac and 40ac, with corresponding conductivity of 20.3%, 23%, 27%, 30%, 35% and% IACS, respectively

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

　　Purpose:

　　1. Power grounding wire, large regulating tube

　　2. Aluminum reinforced core wire

　　3. Secondary cables for electrified railways

　　4. Wires are used for light protection
