A Complete Analysis Of The Manufacturing Process Of Pre-twisted Wire

In the application scenario, steel core aluminum stranded wire is used in UHV lines, and the stranding ratio is 7:1, which takes into account both strength and conductivity. The grounding body of the communication base station is made of all-copper armor rod preformed, with a diameter of 12 mm to meet the requirements of lightning discharge. Stainless steel preformed armour rod is pre-installed in the protective sleeve of the inclined cable of the cross-sea bridge, and the chloride ion corrosion resistance level reaches C5-M. The copper-magnesium alloy stranded wire used in the high-speed rail contact network has a wear resistance of more than 2 million times.
Among the common problems, armor rods material batch differences lead to resistivity fluctuations, and the solution is to establish a raw material traceability system. armor rods for acsr Gear wear of the stranding equipment causes pitch deviation, and preventive measures are implemented every 500 hours. Mandatory maintenance. armor rods transmission line Coating bubbles are mostly caused by excessive humidity, and the relative humidity of the spray room is controlled at 45%-55%. The armour rod ovality of the finished product is often caused by inaccurate mold centering, and a laser calibrator is used for weekly calibration.
The process optimization direction includes the development of an online monitoring system, and armour rod in transmission line the installation of a tension sensor array in the stranding process for real-time feedback adjustment. Experiment with the new armor rods conductor stranding structure and try 19-wire layered stranding to improve the filling factor. Introduce vacuum coating technology to replace traditional spraying to improve coating uniformity. Develop an intelligent warehousing system and use RFID technology to achieve full process traceability.
