In the field of high-voltage cable manufacturing, the smooth aluminum sheath technology has long been an industry challenge. Recently, good news came from the project team of Yuancheng Co., Ltd.'s PHL60-180 smooth aluminum sheath and corrugated aluminum sheath production line——through continuous hard work and technical breakthroughs, the team successfully achieved mass trial production, with multiple core indicators reaching the domestic leading level! Behind this technological breakthrough is the systematic integration and optimization of a number of innovative processes.

In the PHL60-180 smooth aluminum sheath production line and supporting extruder linkage production project, the team of Yuancheng Co., Ltd. worked day and night. From production scheduling, material supply to technical guidance, from mold adjustment, tungsten electrode grinding to take-up and pay-off tension control, every link was pursued with excellence, and finally, the technical problem of high-voltage cable smooth aluminum sheath was overcome in one fell swoop!

Through systematic technical research, Yuancheng Co., Ltd. has achieved significant results in the following fields:

01 Smooth Aluminum Sheath Process

Adopting continuous TIG (Tungsten Inert Gas) welding technology, combined with high-precision roll forming and online detection, the sheath thickness deviation, surface finish, air tightness and bending performance have comprehensively exceeded industry standards!

02 Extrusion Linkage Process

Equipped with 200+120+45 extruders to realize one-time co-extrusion forming of hot-melt adhesive, outer sheath and electrode layer. Cooperated with PID temperature control system, the interlayer bonding strength is greatly improved, completely solving the defects of traditional segmented extrusion process.

03 Leap in Production Effectiveness

The welding speed has increased from 2.8m/min to 6m/min, the production efficiency has increased by 110%, the stability of product quality has been significantly enhanced, and the core indicators are leading in China!

04 Upgrade of Intelligent Control

Equipped with a high-precision automatic tracking system to monitor process parameters in real time, with automatic alarm for abnormalities. The CPK value of sheath thickness has been increased to 1.67, and the production stability has reached a new level!

This technological breakthrough not only demonstrates Yuancheng Co., Ltd.'s production strength and team cooperation spirit, but also injects new impetus into the company's high-quality development. In the future, Yuancheng Co., Ltd. will continue to take innovation as the engine and contribute more "Yuancheng strength" to the progress of the industry!

From technical to efficiency leap, Yuancheng Co., Ltd. has proved with strength that innovation is endless! Kudos to those who are struggling on the front line!
