AI Technical Summary

Technical Problem

In existing industrial robot applications, cables for cable chains or mobile applications often lack both strong transmission capacity and long service life.

Method used

The cable employs a combination design of multiple tinned copper wire bundles forming a conductor, a high-density PE insulation layer resistant to high and low temperatures, a flexible elastomer diameter expansion layer, a low-temperature resistant polyether-type polyurethane outer sheath, and multiple tinned copper wire shielding layers to ensure cable flexibility, shielding effect, and environmental adaptability.

Benefits of technology

It achieves high cable flexibility, stable characteristic impedance, long-life shielding and long drag chain service life, and is suitable for stable data transmission in environments ranging from -40℃ to 80℃.
