A telecommunications cable for making high resistance measurements comprising a plurality of bundles, each comprising a twisted pair of Category 6a copper conductors and a metal foil shield, one of said copper conductors in each twisted pair serving as a signal wire and the other of said copper conductors in each twisted pair being grounded to thereby serve as a noise ground, a braided grounded metal sheath surrounding said plurality of bundles of twisted pairs; and a grounded shield used as an outer sleeve, whereby said cable is triple grounded.

A signal transmission cable includes a first connector, a signal line, a first shielding line, and a second shielding line. The signal line is electrically connected to the first connector. The first shielding line is electrically connected to the first connector, extending away from the first connector, and wound around at least a portion of the signal line along a first rotating direction. The second shielding line is electrically connected to the first connector, extending away from the first connector, and wound around at least a portion of the signal line along a second rotating direction.

A coaxial cable is composed of a conductor, an insulator covering a periphery of the conductor, a shield layer covering a periphery of the insulator, and a sheath covering a periphery of the shield layer. The shield layer is configured to include a lateral winding shielding portion with a plurality of metal wires being helically wrapped around the periphery of the insulator, and a batch plating portion made of a hot-dip plating covering respective peripheries of the lateral winding shielding portion. The shield layer includes a joining portion where the metal wires adjacent to each other in a circumferential direction are joined with each other with the batch plating portion at a spaced portion where the adjacent metal wires are spaced apart from each other, and the non-joining portion where the metal wires adjacent to each other in the circumferential direction are not joined with each other with the batch plating portion at the spaced portion. A length of the non-joining portion along a cable longitudinal direction is shorter than a winding pitch of the lateral winding shielding portion.

A two-core twisted shielded cable includes two insulated wires being twisted together, a metal foil shield, a metal braid, and a sheath. A relationship between an ellipse circumscribing the two insulated wires and a width of the metal foil shield is the width=an elliptical circumference/(1??), and 0.20???0.40. The metal foil shield has a thickness of 15 ?m or more and 120 ?m or less, includes a metal layer and a PET film layer, and 0.10?(a metal layer thickness/a PET film layer thickness)?1.25.

A cable that has a cable core with a first armor wire layer and a second armor wire layer. The second armor wire layer is segregated from the first armor wire layer, and an outer jacket is disposed about the second armor wire layer.
