Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
Shown in Fig. 1-2, the batteries of electric automobile high-voltage line, comprise conductor 1, insulating barrier 2, woven shield 3, lapped shielding layer 4 and sheath 5, be enclosed with insulating barrier 2 in conductor 1 outside, this conductor 1 adopts 73 single copper wires 6 of elder generation to restraint into one, twists again by 19 bursts of regular stranded modes to form again, cabler is furnished with back-twist device when twisting again, can eliminate the stress that multiple strand produces, make more rounding of wire rod, softness.Single copper wire 6 percentage elongations are greater than 25%.Insulating barrier 2 thickness are for being 1.5mm ± 0.1 mm, and this insulating barrier 2 adopts irradiation cross-linking flame-retardant thermo-setting elastomer (XLTPE) insulating material to make.Adopt 10 copper wire bundles to become one at woven shield 3, being interweaved with 24 strands is covered in insulating barrier 2 outsides again, becomes a protective layer closely, plays simultaneously shielding and does usefulness, and the transmission to other models when preventing from transmitting large electric current impacts.Lapped shielding layer 4 is wrapped in woven shield 3 outsides by fixing lay, lapped shielding layer 4 is aluminium foil, aluminium foil surface is inside, and the shield effectiveness in the time of can further strengthening battery high-voltage line electric energy transmitting penetrates into braiding lines the inside when preventing simultaneously the elastomeric material extrusion.Lapped shielding layer 4 outsides pack tightly and are wrapped with sheath 5, sheath 5 thickness are 1.3mm ± 0.1 mm, sheath 5 adopts irradiation cross-linking flame-retardant thermo-setting elastomer (XLTPE) insulating material to make, this material is better than general thermoplastic elastomer (TPE) (TPE) on processability, electrical property, mechanical performance also obviously are better than ordinary hot thermoplastic elastic (TPE) material, on other performances such as environmental protection, chemicals-resistant good performance are arranged also simultaneously.
Satisfying under the condition that electric automobile uses, the advantage of batteries of electric automobile high-voltage line set PVC cable and rubber cable, major embodiment in the following areas:
1. flexibility: the single bare copper wire of conductor raw material selection, percentage elongation is greater than 25% 5 class soft copper silks.The tensile strength of sheath and insulating barrier requires more than the 10Mpa, and hardness 70A(common material is at 80A) guarantee behind the wire forming higher pliability is arranged.
2. resistance to wear aspect: the outer protective sleeve material is wear-resisting, because friction causes wire rod to damage, even broken skin causes security incident in preventing from using.
3. temperature tolerance aspect: the battery high-voltage line can not only use under the cold climate of weather-40 ℃, can also use for a long time under 125 ℃ the condition of high temperature.The new sizing material that cable uses has added crosslinking agent, by irradiation TPE molecule result is changed, and becomes thermosets by thermoplasticity, and temperature resistant grade is high, and various hot property indexs been significantly enhanced.
4. mechanical properties: the tensile strength of battery high-voltage line can reach 10Mpa, percentage elongation 300%, and mechanical performance obviously is better than rubber covered wire and common PVC wire rod.
