And there are same dielectric and shielding construction.Electric current flows to other end from inner conductor one end when normal work, then anti-through outer conductor
Direction is flowed back to.Its principle is that electric current is made to carry out backflow through internal and external conductor, establishes reverse phase magnetic field, due to the section of internal and external conductor
Identical, the electric current flowed through is also identical, so its magnetic field strength generated is equal but contrary, it is right so as to cancel out each other
Magnetic field is not showed outside, achievees the effect that reduce electromagnetic interference and cable itself inductance.The surface of outer conductor is further added by metal simultaneously
