PE insulated computer cable: the guardian of stable signal transmission

In the field of modern industry and data communication, the stability of signal transmission directly affects the reliability of system operation, and every production process of PE insulated computer cable from raw materials to finished products revolves around the core goal of "stability". Whether it is the shaping of the insulation layer, the construction of the shielding layer, or the final quality inspection, through technological innovation and strict control, the process advantages are transformed into a solid guarantee for stable cable transmission. ​
The stable foundation of precise technology​
PE insulated computer cable adopts high-precision extrusion technology. During the production process, the PE material is heated and melted by the barrel and continuously pushed to the mold through the screw. Temperature control is the core of the extrusion process. If the temperature is too high, the PE material is prone to degradation, resulting in a decrease in insulation performance; if the temperature is too low, the fluidity is insufficient and a uniform and dense coating layer cannot be formed. The production equipment uses an intelligent temperature control system to accurately control temperature fluctuations within a very small range to ensure uniform plasticization of the material. The pressure and extrusion speed need to be coordinated with the temperature parameters. Insufficient pressure will make the insulation layer and the core not fit tightly, while excessive pressure may cause extrusion deformation. Stable extrusion speed combined with the traction device can ensure the uniform thickness of the insulation layer, smooth surface and no bubbles, thereby effectively avoiding signal leakage or attenuation caused by defects in the insulation layer, and laying a physical foundation for stable signal transmission. ​
Protection upgrade of automated process​
The shielding layer is a key structure to resist external electromagnetic interference, and the fineness of its manufacturing process directly affects the cable's anti-interference ability. The shielding layer of the PE insulated computer cable adopts automated braiding and wrapping technology. The aluminum foil shielding layer is tightly fitted to the core with constant tension through high-precision wrapping equipment to ensure no wrinkles or gaps, and to isolate electromagnetic interference to the maximum extent; the outer braided copper mesh uses a high-speed braiding machine to accurately control the braiding density and angle to form a continuous and uniform shielding structure. Automated equipment not only improves production efficiency, but also ensures the consistency and reliability of the shielding layer. During the weaving process, the equipment monitors the copper wire tension and weaving status in real time. Once an abnormality occurs, it will immediately warn and automatically adjust to ensure that the shielding layer of each cable can play the best protection effect and build a solid electromagnetic barrier for signal transmission. ​
Strict performance escort ​
After production is completed, each cable must undergo multi-dimensional electrical performance tests. The insulation resistance test measures the insulation layer resistance value by applying a specific voltage to determine whether its insulation performance meets the standard, preventing leakage or signal attenuation due to insulation layer defects; the capacitance test detects the capacitance parameters between the wire cores to ensure the stability and accuracy of signal transmission; the attenuation test simulates the actual transmission scenario, measures the signal attenuation degree at different frequencies, and verifies the performance of the cable in high-frequency signal transmission. It also includes physical performance tests such as bending tests and temperature resistance tests to evaluate the reliability of cables in different environments. Only when the cable meets strict standards in all test items can it obtain factory approval, and with full-process and high-standard quality control, it can ensure that each cable can perform stably after being put into use. ​
The core support of stable performance ​
The realization of stable performance of PE insulated computer cables is essentially the result of the synergy of a complete and precise process system. From the high-precision extrusion of the insulation layer, to the automated intelligent manufacturing of the shielding layer, to the rigorous quality inspection of the entire process, each link is closely connected and mutually influential. This systematic process guarantee gives the cable stable and reliable signal transmission capabilities, enabling it to adapt to the stringent requirements of complex application scenarios such as industrial automation and data centers.
