HV Cable Braided Shield Processing

The processing of shielding layers for new energy power cables is a highly specialised and critical process, primarily used in high-voltage wiring harnesses (connections between batteries, motors, and electronic controls) in new energy vehicles, as well as in charging piles and energy storage systems.


Shielding mesh typically refers to a mesh material woven from metal wires (such as tinned copper wire or stainless steel wire). Its advantages include good flexibility and bend resistance, making it suitable for scenarios requiring frequent movement (such as cables connecting motors and batteries). Its core function is to suppress electromagnetic interference (EMI), ensuring that internal and external electronic equipment (such as vehicle radar, audio systems, and control systems) is not affected by the electromagnetic fields generated by high-voltage, high-current power cables, thus preventing malfunctions.


Folding (or combing) the shielding layer is the most skill-intensive step, preparing for the installation of the connector housing (usually a metal shielding shell).


Brush: The woven shielding mesh is broken up using a metal brush composed of extremely fine nylon or metal wire bundles.


Cut: The long strips of shielding mesh are precisely cut and separated to a predetermined length.


Fold: Simultaneously or after breaking, the remaining woven layer is bent into shape.
