丰台电务工程段试验成功一项小同轴电缆焊接接续新工艺,这项新工艺采用低压6伏直流(或交流)电源,从对接导体(芯线或管线)两端送入,电流流过对接处产生热效应,使导体(芯线或管线)在对接处熔接,熔接时使用磷铜合金焊料作为助焊剂。为了保证焊接质量和电缆的良好复原,焊接前后,要使用特制的几种小工具,进行剥切、开管、剪接、卡固、焊接、矫管、复管等工作。过去小同轴电缆接续是采用压接法,其缺点是焊接处容易氧化,导电可靠性差,受力不均匀,不易检查接续质量。采用新工艺后,焊 Fengtai electricity project segment successfully tested a new small coaxial cable welding process, the new technology uses low-voltage 6-volt DC (or AC) power supply from the docking conductor (core or pipeline) at both ends into the current flow Docking Department has a thermal effect, so that the conductor (core or pipe) at the docking weld, the use of phosphor bronze alloy solder as a flux. In order to ensure the quality of the welding and the good recovery of the cable, several special tools should be used before and after welding to perform the work such as peeling, opening, splicing, fastening, welding, straightening and compounding. In the past, the small coaxial cable connection was made by crimping method. The disadvantage was that the welding place was easily oxidized, the conductive reliability was poor, the force was not uniform, and the connection quality was not easy to be inspected. After using the new technology, welding
