Abstract
The utility model discloses a high-voltage electric machine lead wire, which is characterized in that a conductor is formed by the composite stranding of tinned copper wire through the standard bunch strand and strand, the outside of the conductor is sequentially provided with a conductor shielding layer and an insulating layer which form an insulating core, and an outer protective sleeve layer is extruded outside a single insulating core to form the lead wire of the electric machine. The utility model can be suitable for the high-power motor and various different operating environments, has the properties of flexibility, humidity resistance, weather resistance, wear resistance, environment protection, long service life and the like, and has strong overload capacity.
Description
Technical field
The utility model relates to a kind of motor lead, relates in particular to the wiring of a kind of high voltage power traction, belongs to technical field of electric wires and cables.
Background technology
Motor lead is mainly used in the power transmission link between electric transportation and distrubution apparatus and the motor device, also can be applicable to hv transmission line.
Along with the needs of the increase of power of motor, the cable transmission power of transmission of electric energy also increases thereupon.Traditional employing increases electric machine structure or the cross-section of cable is difficult to reach requirement, and state-of-the-art technology is that the electric pressure that improves motor and cable improves its power at present.The cable that is connected with high-tension electric motor, if adopt present structure: soft copper conductor, insulating barrier and restrictive coating, along with the rising of voltage, can cause phenomenons such as corona, partial discharge, make cable heating or thermal breakdown, the aging quickening influences the useful life of cable.
The utility model content
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of high-tension electric motor lead wire, make it adapt to heavy-duty motor, multiple different operational environment, and have performances such as pliability, moisture-proof, weather-proof, resistance to wear, the feature of environmental protection, long-life, stronger overload capacity is arranged.
The utility model technical solution problem adopts following technical scheme:
The wiring of the utility model high voltage power traction, its design feature is conductor to be set adopt tinned copper wire by orthodox beam strand and burst compound stranded formation of strand, outside conductor, set gradually conductor shield and insulating barrier and form insulated wire cores, outside single insulated wire cores, extrude external sheath layer and constitute described motor lead.
Described conductor adopts the 5th class conductor or the 6th class soft copper.
Described conductor shield is the overlapping wrapped formation of two-sided semi-conductive cloth tape.
Described insulating barrier is to be material with the ethylene-propylene rubber compound.
Described external sheath layer is extruded outside insulating barrier by polyurethane material and forms.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model conductor adopts tinned copper wire, can prevent effectively that copper conductor from increasing problems such as heating because of oxidation makes itself and joint resistance; Conductor structurally adopts orthodox beam strand, strand strand composite construction, and symmetrical configuration makes that cable is stressed in BENDING PROCESS evenly to be stablized.
Advantages such as 2, the utility model adopts the 5th class conductor or the 6th class conductor, and it is more soft that cable is had, and bending radius is very little;
3, insulating barrier is to be material with softness, superior electrical performance, high mechanical properties and the ethylene-propylene rubber mixture that meets the ROHS of European Union instruction in the utility model, and process is reliable and stable, easy to operate.Material source is wide, and price is low, and production cost is low, and material resistance is higher, and dielectric loss is less.Simultaneously, such material can make the highest long-term permission serviceability temperature of conductor can reach 90 ℃, the current-carrying capacity of cable height, and it is strong to bear overload capacity.
4, the utility model conductor shield adopts two-sided semi-conductive cloth tape, and even conductive surface electric field reduces the rough and point discharge phenomenon that causes of conductive surface, has improved cable useful life.Technology is simple, easy to process simultaneously, increases manufacturing cost not significantly.
5, middle external sheath layer of the present utility model adopts polyurethane material, its superiority is embodied in: the environment broad that (1) adapts to, be not easy to because of various environmental factor hardening or crisp, also unlike PE, wear out and stress cracking, cause that the electric property of cable and environmental resistance reduce; (2) have the same with rubber wear-resisting, soft, characteristics that weather resisteant is good, its processing technology is much simpler than rubber simultaneously, can materials such as same PVC, PE equally adds hot-extrudablely, and need not vulcanize; (3) under-60 ℃ of low temperature condition, still can keep good bending property, even repeatedly also can not ftracture with very little bend radius; (4) such material has the feature of environmental protection, meets the ROHS of European Union instruction; (5) in atmosphere such as greasy dirt, chemicals, soda acid, also has premium properties; (6) this material can satisfy the requirement in 90 ℃ of ambient temperatures and following long-term work.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 conductor, 2 conductor shields, 3 insulating barriers, 4 external sheath layers.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, conductor in the present embodiment 1 adopts tinned copper wire by an orthodox beam strand and burst compound stranded formation of strand, and symmetrical configuration makes that cable is stressed in BENDING PROCESS evenly to be stablized.
Outside conductor, set gradually conductor shield 2 and insulating barrier 3 formation insulated wire cores, outside single insulated wire cores, extrude external sheath layer 4 and constitute described motor lead.
In the specific implementation process, conductor 1 adopts the 5th class conductor or the 6th class conductor; Conductor shield 2 is the overlapping wrapped formation of two-sided semi-conductive cloth tape; Insulating barrier 3 is to be material with the ethylene-propylene rubber compound; External sheath layer 4 is extruded outside insulating barrier 3 by polyurethane material and forms.
