In order to solve the problems of the technologies described above; The utility model provides a kind of electric automobile list/three-phase charging private cable; This electric automobile list/three-phase charging private cable comprises cable cover(ing); In this cable cover(ing), be provided with the control line of forming by the control heart yearn of two insulated, four mutually insulateds power line and with the earth connection of control line, power line mutually insulated; The cross section annular of this cable is distribution control line, four power lines and an earth connection evenly; This control line, four power lines and an earth connection are that centres is stranded with flexible reinforcement, and said control line comprises the control line sheath, in this control line sheath, is provided with the control heart yearn that two outsides are coated with the control heart yearn sheath of insulation respectively.
Preferably; Said flexible reinforcement is the aramid fiber tow; The external diameter of this aramid fiber tow and cross section annular evenly distribution control line, four power lines contacts with earth connection, and the aramid fiber tow fills up fully just by control line, four power lines and contacts the intermediate gaps that stays when stranded with earth connection.
Preferably, two control heart yearns that are provided with in the said control line are stranded each other, and its lay is between 50-100mm.
Preferably, the ground connection heart yearn of the power supply heart yearn of the control heart yearn of said control line, power line and earth connection is many soft copper electric wire lay configuration.
The utility model electric automobile list/three-phase charging private cable; Power line through the control line of in this cable cover(ing), forming, four mutually insulateds by the control heart yearn of two insulated and with the earth connection of control line, power line mutually insulated; The cross section annular of this cable is distribution control line, four power lines and an earth connection evenly; Be provided with a branch of flexible reinforcement in the ring of encirclement that is formed by said control line, four power lines and earth connection, wherein said control line, four power lines and an earth connection are that centres is stranded with flexible reinforcement.Compared with prior art; Because this private cable is provided with control line; This control line can be transferred to control signal the control circuit of vehicle-mounted charge machine or power end; Before directly transfering to plug, cut off the power supply, thereby the potential safety hazard that the electric arc of generation causes can avoid the vehicle-mounted charge machine of electric automobile to fill unexpected the disconnection with the AC power plug time; Because stranded each other according to the control heart yearn by two in this control line, control line and four power lines and an earth connection are that centres is stranded with flexible reinforcement, can reduce the diameter of private cable simultaneously, thus convenient moving.
In the ring of encirclement of said control line, four power lines and an earth connection formation, be provided with flexible reinforcement, can improve the resistance to tension of private cable line, prolong the useful life of cable.
Said control heart yearn, power supply heart yearn and ground connection heart yearn adopt by many soft copper electric wire lay configuration, guarantee the flexibility of heart yearn low resistance high conductivity and cable.
