Shielding material: aluminium foil and copper wire braid - a strong bulwark against electromagnetic interference

The shielding material is the core element that determines the strength of the cable'santi-interference ability, and its main function is to effectively resist electromagnetic interference (EMI) and radio frequency interference (RFI), forthe clear and stable transmission of signals. Aluminium foil and copper wire braid are widely used in the construction of the shielding layer of security communication cables due to their excellent conductivity and excellent shielding effect.

In Tianjie Industry, the selection and application of shielding materials show its high professional standard. Aluminium foil shielding is made of high-purity aluminium alloy, which undergoes a precision rolling process, and the thickness error can be accurately controlled within ±0.01mm. Before each roll of aluminium foil is putinto use, it has to undergo strict conductivity and surface finish tests to ensure that its shielding effect reaches the best state. The copper wire braided shielding is made of high purity copper wire with a braiding density of≥90%, thus ensuring the optimum shielding effect in all aspects.

In the production process, TIANJIE introduces fully automated shielding layer wrapping equipment,which ensures 100% coverage and fit of the shielding layer through advanced automation technology. Each production process is under precise control, and the thickness error of the shielding layer is strictly controlled within ±0.005mm. In addition, TIANJIEhas innovatively developed double-sided aluminium foil shielding technology, which further improves the anti-interference capability of the cable and enables it to operate stably in complex electromagnetic environments.

TIANJIE's strict control of shielding materials, from the careful selection of raw materials toevery aspect of the production process, demonstrates extremely high standards.From the beginning of the winding process to the completion of the final lamination, each process undergoes strict and meticulous quality testing to ensure that the shielding performance is always maintained at the industry'stop level. It is this extreme pursuit of quality that makes Tianjie cable win wide recognition in the market and become a quality product trusted by users.
