  • Uniform twisted wire pair electrical ribbon cable
    Patent number: 4486619
    Abstract: An electrical ribbon cable containing a plurality of longitudinally extending, individually insulated wire pairs being twisted together. An insulator is bonded to the plurality of wire pairs during only a portion of each individual twist of the wire pairs. The insulator holds the plurality of wire pairs in a fixed planar relationship. The wire pairs have a uniform twist period and have transversely aligned crossover points between wire pairs. The resultant cable combines the desirable electrical characteristics of a twisted pair cable with the desirable connectability characteristics of a parallel lay electrical ribbon cable.
