The technical solution adopted in the present invention is as follows：

A kind of high flexibility aluminium alloy cable used for electric vehicle, including conductive core, the conductive core pass through many soft aluminium Stranded after the first synnema of the thin monofilament of alloy to form, the thin filament diameter of soft aluminium alloy is 0.10mm~0.30mm, and tension is strong Degree is more than 120MPa, and elongation at break is more than 25%, and conductance is more than 60%IACS；The pitch of synnema be external diameter after synnema 20~ 25 times, twisting pitch is 16~20 times of stranded rear external diameter, synnema and stranded all uses left-hand；The outside cladding of the conductive core There is insulating barrier, insulating barrier is the 125 DEG C of EP rubbers mixtures of heatproof extruded, and its tensile strength is more than 7.0 MPa, extension at break More than 250%, specific insulation is equal to 2.0 × 1015 Ω cm, tensile strength and fracture after 158 DEG C × 7d watertight aircase agings Elongation change rate is less than ± 15%；The outside of the insulating barrier is coated with outer jacket, and outer jacket is the LSOH anti-flaming extruded Thermoplastic polyester elastomer TPEE, insulating barrier periphery is coated on by extruding machine extrusion, and its tensile strength is more than 15.0 MPa, breaks Elongation is split more than 300%；Fire-retardant rank reaches UL-94V-0 grades, and oxygen index (OI) is more than 27；Low smoke, zero halogen performance：Burn light transmittance More than 80%, content of halogen is less than 0.05%, and pH value is more than 4.3, and electrical conductivity is less than 10 μ s/mm.

Its further technical scheme is：

The mode that insulating barrier is coated in conductive core is squash type, and vulcanization is vapor crosslinking, conditions of vulcanization：Vapour pressure Power 0.7~1.0 MPa, 10~20min of time；

Outer jacket extrudes thickness range 1.0mm~2.5mm, and color is orange.

Beneficial effects of the present invention are as follows：

High flexibility aluminium alloy cable used for electric vehicle of the present invention, using strand after many soft first synnemas of aluminum-alloy wire Close, synnema is consistent with direction of lay so that cable softness light weight, flexibility is good, economical and practical；Insulating barrier is using the heatproof extruded 125 DEG C of EP rubbers mixtures, flexibility is good, temperature resistant grade is high, halogen-free environmental；Outer jacket is the LSOH anti-flaming heat extruded Plasticity polyester elastomer TPEE, -60 DEG C of temperature in use scope~160 DEG C, soft abrasion-resistant is environmental and durable.
