Electric cable for 3G data communication

The utility model relates to an electric cable for 3G data communication, belonging to the technical field of electric wires and electric cables. The electric cable for the 3G data communication comprises a cable core and a sheath layer, wherein the cable core comprises at least two first wire pairs, second wire pairs and an isolation layer. The electric cable for the 3G data communication is characterized in that: each first wire pair consists of a pair of first conductors which are coated with first insulating layers respectively, a first strand-coated layer, a second strand-coated layer and a first shielding layer; each second wire pair consists of a pair of second conductors which are coated with second insulating layers respectively and a second shielding layer; the stranding pitch of the pair of second conductors is different from that of the pair of first conductors; the second wire pairs are positioned between two adjacent first wire pairs; the second shielding layer is positioned outside the second conductors; the isolation layer is positioned outside the first wire pairs and the second wire pairs; and the first conductors and the second conductors are formed by stranding a copper foil wire with a plurality of tinned copper wires or a plurality of soft copper wires respectively. The electric cable for the 3G data communication has the advantages of ensuring a communication effect; prolonging the service life of the electric cable; improving the adaptability of the electric cable to usage occasions; and having an effect of resisting low temperature.
