What is the difference between copper strip and copper-plastic composite strip?

First, the thickness of the copper foil in the copper-plastic composite tape is smaller than the thickness of the copper tape, so a plastic layer is needed to increase the strength, which is convenient for processing and can reduce the cost.

Secondly, the plastic layer melts under heat and blocks the gap, which can play a waterproof role.

However, due to the action of plastics, a closed shielding structure cannot be formed, and there are differences in the shielding effect. Different materials are selected depending on the use of the cable.

Different shielding forms are used depending on the occasion. Copper-plastic composite tape I also want to improve the flow rate while ensuring the cable has certain waterproof performance. I personally think that the latter may be more important. Generally speaking, this kind of structure is mostly in the form of vertical package, so that the above two kinds can be obtained. effect.

For the mere construction of the shielding structure (mainly in the form of wrapping), the copper-plastic composite tape cannot be used. Firstly, the cross section of such a copper is certainly small, which has an influence on the transmission of the short-circuit current of the cable, and secondly Since the tape has a plastic film, the film is easily bonded to the sheath when the outer sheath is extruded, and the current transfer direction in the copper strip is changed. But if the user does not ask for it, using such a tape is a good thing for the manufacturer, which can save costs! !

The copper-plastic composite tape can be used on a cable with a small outer diameter and a soft requirement. In practice, a small cross-section leak line can be added to compensate for the current transmission. The copper strip is not ideal for wrapping on these small outer diameters and cables that require softness.
