The invention discloses a production process of a steel-cored aluminum strand, and relates to the technical field of cable production, and the production process of the steel-cored aluminum strand comprises the following steps: step 1, raw material preparation and inspection: selecting a high-carbon steel wire rod, a galvanized steel wire and an aluminum single wire for inspection according to lead use requirements; after the surface of the steel wire rod is treated, the steel wire rod needs to be cold-drawn into the steel wire, and in order to improve the corrosion resistance of the steel wire, the surface of the steel wire is galvanized; according to the production process of the steel-cored aluminum stranded wire, the steel-cored aluminum stranded wire is formed by stranding the high-conductivity aluminum wire stranding layer and the galvanized steel wire, the welding or crimping technology is adopted at the joint of the aluminum wire stranding layer and the steel wire before stranding, and the stranded steel-cored aluminum stranded wire needs to be subjected to heat treatment; the heat treatment can improve the conductivity, strength and hardness of the stranded wire. And a solid insulating layer needs to be extruded outside the stranded wire, so that the functions of improving the insulating property and enhancing the overall strength of the stranded wire are achieved.

This invention relates to the field of cable auxiliary tools, specifically to an electric taper for high-voltage cable reaction cones. It includes a base, a power supply on the base, a frame on one side of the power supply, clamping systems symmetrically arranged on both sides of the frame for clamping cables, a cutting system for cutting cables within the frame, and a power system providing power to the cutting system. It also includes a control box. The power system includes a motor mounted on the frame, with the motor's output shaft passing through the frame and connected to a first gear via a belt. The first gear meshes with a second gear, which is connected to the cutting system. The second gear has an axially through-type structure for the cable to pass through. This application, through the integrated design of the base, frame, clamping system, cutting system, power system, and control box, achieves automated, high-precision, and multi-scenario adaptability in cable reaction cone manufacturing, significantly improving construction efficiency and joint quality.
