Shielded terminal wire consists of ordinary insulated conductors in a standard conductive layer with a special protective shield. This shielding differentiates these cables from common unshielded variants, the shielding is wrapped around an insulated conductor, usually developed from braided copper and similar metal strands, helical copper tape, conductive polymers, etc. .

Shielded cables reduce and isolate the transmission of data or power from the high electrical power "electrical noise" or ambient electromagnetic interference (EMI) present in industrial, engineering or manufacturing environments where data and power transmission is subject to electronic interference. In some industries, shielded terminal wires are very useful.
According to the length of the terminal strip, two or more shielding brackets AB-SK are installed. This bracket makes the front bus bar and the guide rail not only electrically and mechanically connected, and thus connected to the grounding of the equipment shell, the installation of the shielding terminal is very simple, Just snap the SK terminal to the bus bar after wiring.
