In many electronic applications, two wires are required to complete circuits; these are often referred to as "balanced arrays" or "twisted pair" constructions. Paired cable designs, like Carol® brand constructions, find frequent application in circuits requiring circuit-to-circuit isolation from noise, minimization of capacitance imbalances and a reduction of EMI interference currents. Circuit separation is further enhanced in those designs employing individual circuit shields in concert with an overall shield. These shielding systems are available from general cable in myriad combinations to suit the unique needs of the circuit designer.. Images shown for wire are for illustrative purposes only.
