Abstract
The utility model provides a special high-voltage motor lead wire comprising a conductor, a thermal-protective layer and an insulating layer, wherein the conductor is formed by compound stranding of ultrafine copper wires, the thermal-protective layer and the insulating layer are arranged outside the conductor in sequence and form an insulated core, and a jacket further wraps outside the insulated core. The utility model provides a special high-voltage motor lead wire which is good in overall good heat dissipation effect, soft, portable, and good in bending property.
Description
Technical field
The utility model relates to the electric wire field, refers to especially a kind of for the extraordinary lead wire on high-voltage motor.
Background technology
Motor lead namely connects the power transmission line between motor device.Traditional motor lead, when power of motor is larger, the one,, cause cable heavy, bending property is poor; The 2nd,, the lead wire heating is serious, and the operating time is short, can't satisfy the demand for development of high-tension electric motor.
The utility model content
The utility model proposes the extraordinary lead wire of a kind of high-voltage motor, solved the problem that in the prior art, electric wire is heavy, bendability is poor, heating is serious.
The technical solution of the utility model is achieved in that the extraordinary lead wire of a kind of high-voltage motor, comprise conductor, thermal insulation layer, insulating barrier, described conductor is to be twisted again by ultra-fine copper wire to form, described conductor sets gradually thermal insulation layer and insulating barrier outward, and described thermal insulation layer and insulating barrier consist of insulated wire cores; Described insulated wire cores also is coated with sheath outward.
Further comprise, described thermal insulation layer is the high temperature resistance polyester thermal insulation layer, and described thermal insulation layer surrounds Duplication on conductor between 25%-50%.
Further comprise, described insulating barrier is high temperature resistant silica gel.
Further comprise, described sheath is chloroprene rubber sheath.
Beneficial effect: the utility model has solved the defective that exists in the background technology, and conductor adopts the ultra-fine copper wire of multiply to twist again and forms, Stability Analysis of Structures, and flexibility is high, has improved the bending property of lead wire; Set gradually thermal insulation layer and insulating barrier and form insulated wire cores outside conductor, then extrude restrictive coating formation motor lead outside single insulated wire cores.The conductor thermal insulation layer adopts the high temperature resistance polyester band wrapped, and wrapped Duplication improves insulation property between 25%-50%.Insulating barrier adopts high temperature resistant silica gel, and dielectric constant is low, and the ageing of insulation excellent performance is compared with the ordinary silicon rubber insulation, under identical ampacity, under identical electric pressure, it is thinner that insulating barrier can be done, the integral heat sink of lead wire is effective like this, and is more soft, light, good bending property.Temperature resistant grade is high simultaneously, and allowing maximum operating temperature is 180 ℃.Restrictive coating adopts all reasonable neoprenes of resistance to wear, oil resistance.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the utility model;
Wherein: 1, conductor; 2, thermal insulation layer; 3, insulating barrier; 4, sheath.
Embodiment
As shown in Figure 1, the extraordinary lead wire of a kind of high-voltage motor, comprise conductor 1, thermal insulation layer 2, insulating barrier 3, described conductor 1 is to be twisted again by ultra-fine copper wire to form, Stability Analysis of Structures, flexibility is high, has improved the bending property of lead wire, outer thermal insulation layer 2 and the insulating barrier 3 of setting gradually of described conductor 1, described thermal insulation layer 2 and insulating barrier 3 consist of insulated wire cores; Described insulated wire cores also is coated with sheath 4 outward.Thermal insulation layer 2 adopts the high temperature resistance polyester band wrapped, and wrapped Duplication improves insulation property between 25%-50%.Insulating barrier 3 adopts the high temperature resistant silica gel of import, and dielectric constant is low, and the ageing of insulation excellent performance is compared with the ordinary silicon rubber insulation, under identical ampacity, under identical electric pressure, it is thinner that insulating barrier 3 can be done, the integral heat sink of lead wire is effective like this, and is more soft, light, good bending property.Temperature resistant grade is high simultaneously, and allowing maximum operating temperature is 180 ℃.Restrictive coating 4 adopts all reasonable neoprenes of resistance to wear, oil resistance.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
