There is an existence of a "Skin effect" in each conductor. It is the alternating electrical current in the conductor, or alternating electromagnetic field, where some current will stay concentrated on the surface of the conductor. This causes the current within conductor to create a phenomenon of uneven vortex dispersion. This "Skin effect" makes the resistance of the conductor to increase along with the rise in frequency of the alternating current, which reduces the wire current transmission efficiency. The end result is energy consumption efficiency achieved.

BTL deploys the intertwining structure of multi-strand metal wire woven into a group of independent conductors causing the electromagnetic field to be evenly distributed, creating a "skin effect" offset phenomenon and producing an "electromagnetic shielding" effect at the same time. The resultant "electromagnetic shielding" effect efficiently deadens the electromagnetic waves that penetrate the conductor, in order to ensure a superior uninterrupted transmission process.
