Abstract

The invention discloses a power cable for new energy automobiles. The power cable is characterized in that a conductor formed by stranding six types of bare copper metal wires is adopted, the outer layer of the conductor is wrapped with a thermoplastic rubber insulating layer, a double-layer shielding layer is arranged outside the insulating layer, an inner shielding layer in the double-layer shielding layer is a metal strap wrapped shielding layer, an outer shielding layer in the double-layer shielding layer is a woven wire mesh shielding layer, and the surface layer of the cable is wrapped with a 125 DEG C outer irradiation crosslinking polyolefin sheath. The cable disclosed by the invention can withstand large currents and high voltages, and is high and low temperature resistant, oil preparation resistant, low-smoke, halogen-free and flame-retardant; and the cable has the outstanding pliability of being especially suitable for power cables required by new energy automobiles.

Description

A kind of new-energy automobile is used power cable
Technical field
The present invention relates to a kind of power cable, a kind of ultra flexible cable that is mainly used on the new-energy automobile as major impetus transmission usefulness of more specifically saying so.
Background technology
In the today of advocating green energy resource; Solar energy, wind energy, luminous energy etc. are constantly being developed as the form of new forms of energy; The new-energy automobile abandoning tradition utilize fuel engines as power change into utilize pure electric energy engine widely promoted as dynamical system by the world and obtain understanding, China also begins to develop the new-energy automobile field.
The dynamical system of new-energy automobile is need electric power be transferred on the motor by storage battery, makes engine rotation, also needs the engine of automobile own to give the charging of accumulate pond for the charging of accumulate pond and the external world simultaneously.Because the cable that present China is used on the automobile all is the lead of some small bores; These leads are the connections that are used for instrument and meter; Can not transmit big electric energy, and mostly industrial power cable mainly is the underground piping mode because of its system of laying, hardness is higher; Can not on automobile, lay (its space is narrower, needs the cable softness to be easy to bending).Simultaneously, in the today of advocating environmental protection, characteristics such as low cigarette, Halogen, fire-retardant, environmental protection by new energy field as its basic demand.Also there is not a kind of cable that is particularly suited for being applied on the new-energy automobile as power transmission usefulness in the prior art.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provide the new-energy automobile of a kind of softness, heavy in section, environment-friendly type to use power cable, making it be particularly suited for being applied on the new-energy automobile as power transmission cable.
New-energy automobile of the present invention with the design feature of power cable is: the conductor that adopts six types of stranded formations of naked copper wire; The outer coating thermoplastic vulcanized rubber insulating barrier of said conductor; The double layer screen layer is set outside said insulating barrier; Internal layer screen in the said double layer screen layer is that wrapped metal tape screen, outer screen are braided metal net screen, at 125 ℃ of cross-linking radiation polyolefin oversheaths of extexine coating of said cable.
New-energy automobile of the present invention also is with the design feature of power cable:
Said conductor is to constitute by six types of naked copper wires of 600-2000 root Φ 0.20mm are stranded, and stranded mode is at first to restraint with the naked copper wire to be twisted into thigh, forms a stranded conductor through a burst strand again, and said burst of strand is set to the strands form of 19 strands or 37 strands.
Said metal tape screen adopts aluminium-plastic tape, the rate of putting up of the wrapped employing 50% of said aluminium-plastic tape, and aluminium towards outside.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, six types of bare copper wires of conductor employing of the present invention are processed through a bundle strand and a burst strand, and its structure is tight, rounding, make cable very soft, and bending radius can reach 1 times of cable size.
2, the present invention has adopted the wrapped double layer screen mode that adds braid shielded of aluminium foil, can make cable reach the effect of 100% shielding, reduces the electromagnetic interference of instrument and meter to external world.
3, use TPV among the present invention, its long-term work temperature can reach 125 ℃, and the material that has changed 125 ℃ of heatproofs in the prior art must adopt the mode of cross-linking radiation or vulcanization crosslinking, and its extruding-out process is simple, smooth and soft surface.
4, the present invention adopts TPV and cross-linking radiation polyolefin; Have environmental protection, low cigarette, Halogen, fire-retardant characteristic; The whole cable amount of being fuming is very little; The smoke density light transmittance can reach 90%, is higher than both at home and abroad the requirement of 70% the light transmittance of stipulating at trolley coach and shipboard cable far away.
5, among the present invention by the stranded conductor that constitutes of six types of naked copper wires of 600-2000 root Φ 0.20mm, it is remarkable as the electric cable with large cross-section softness, is particularly suitable in narrow space, laying.
6, metal tape screen of the present invention adopts aluminium-plastic tape; The rate of putting up of the wrapped employing 50% of its aluminium-plastic tape; And aluminium towards outside; Between the wire netting of aluminium face and outer braid metal mesh shield layer, form excellent contact, can effectively conduct the charge inducing of aluminium foil surface, reach excellent shield effectiveness.
7, the present invention as new-energy automobile with cable especially between storage battery and motor as carrying out the transmission of electric energy.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Label among the figure: 1 conductor; 2 insulating barriers; 3 metal tape screens; 4 braided metal net screens; 5 oversheaths.
Embodiment
Referring to Fig. 1; New-energy automobile with the version of power cable is in the present embodiment: with the stranded formation conductor 1 of six types of naked copper wires of many Φ 0.20mm; The mode coating thermoplastic vulcanized rubber insulating barrier 2 that the skin of conductor 1 extrudes through fusion; The double layer screen layer is set outside insulating barrier 2; Internal layer screen in the double layer screen layer is that wrapped metal tape screen 3, outer screen are the metal mesh shield layers 4 that the tinned copper wire by Φ 0.12mm is woven into, and coats 125 ℃ of cross-linking radiation polyolefin oversheaths 5 at the extexine of cable.
In the practical implementation, conductor is to constitute by six types of naked copper wires of 600-2000 root Φ 0.20mm are stranded, and stranded mode is at first to restraint with the naked copper wire to be twisted into thigh, forms a stranded conductor through a burst strand again, and burst strand is set to the strands form of 19 strands or 37 strands.
The metal tape screen adopts aluminium-plastic tape; The rate of putting up of the wrapped employing 50% of aluminium-plastic tape; And aluminium towards outside; This version forms excellent contact between the wire netting of aluminium face and outer braid metal mesh shield layer, can effectively conduct the charge inducing of aluminium foil surface, reaches excellent shield effectiveness.
