A cable includes: a core wire; an insulating layer covering the core wire in an extrusion molding manner, a shielding layer covering the insulating layer, and a sheath covering the shielding layer, the core wire comprising a pair of inner conductors and the inner insulating layer of the pair of inner conductors are simultaneously covered by extrusion molding. Under the premise of ensuring impedance matching, the cable reduces the distance between the two conductors, so that the cable has lower insertion loss, and the overall size of the cable is also smaller, at the same time, the cable has a high-speed data transmission capability with a signal frequency greater than 40 GHz.

A dielectric isolator for a twisted pair cable includes a body formed as an elongate strip with a top surface, bottom surface, a first side edge and a second side edge. A first slot is formed in the first side edge and extends at least half way toward the center of the isolator. A second slot is formed in the second side edge and extends at least half way toward the center of the isolator. During cable manufacturing, first and second wedges open the first and second slots. First and second twisted pairs are inserted into the first and second opened slots, respectively. Third and fourth twisted pairs reside at the top and bottom surface, respectively.

The present disclosure relates a low-toxicity flame-retardant polyolefin-based insulating resin composition, a low-toxicity flame-retardant polyolefin-based insulated electric cable, and a method of manufacturing the insulated electric cable. The low-toxicity flame-retardant polyolefin-based insulating resin composition includes 100 parts by weight of a base resin and 120 to 140 parts by weight of a flame retardant. The base resin includes 20% to 40% by weight of polyethylene ethyl acrylate, 20% to 40% by weight of polyolefin elastomer, and 30% to 40% by weight of a linear low-density polyethylene resin grafted with maleic anhydride. The flame retardant is magnesium hydroxide that is surface-treated with a silane coupling agent. With the use of the composition, the low-toxicity flame-retardant insulated wire exhibiting good electrical insulation and anti-scratch characteristics and having good appearance can be obtained.
