What is the difference between copper strip and copper plastic composite belt?
The copper plastic composite belt can be used on cables with small outer diameter and soft requirements, and a small section of leakage line can be added in actual use to compensate for the transmission of the current. The copper strip is not ideal for wrapping on these small outer diameter and flexible cables.
However, due to the role of plastic, it can not form a closed shielding structure, there is a difference in shielding effectiveness, according to the different use of cable, choose different materialsDifferent shielding forms are adopted according to different occasions. Take me to the copper plastic composite user is also in order to improve the flow and ensure the cable has certain waterproof performance, personally think that may be important, generally speaking the structure most of the longitudinal form, it is possible to obtain the two effects.For the simple structure for shielding Yong (mainly refers to the winding form), copper plastic composite strip is not used, the first section of this certainly small copper belt, transmission of short-circuit current on the cable is affected when the tape, then because of the plastic film, when the film in the extrusion jacket easily with the sheath bonding, at the same time the method change current through the transmission direction of the copper strip. But if the user does not ask, the use of such tapes is a good thing for manufacturers and saves costs!!
Second, the plastic layer melts and blocks the gap under the condition of heating, and can play the role of waterproof.
Firstly, the thickness of copper foil in copper plastic composite belt is less than that of copper strip, so a layer of plastic layer is needed to increase strength, facilitate processing and reduce cost.
