Abstract
The utility model discloses a tear-resistant silicone rubber insulated lead wire for motors. The lead wire comprises an alloy conductor, wherein a refractory layer and a silicone rubber insulating layer are sequentially wrapped on the outer side of the alloy conductor; a meshy tear-resistant layer weaved by high-carbon alloy wires is arranged on the outer wall of the silicone rubber insulating layer; a sheathing layer is formed outside the tear-resistant layer through extrusion molding; and a sheath material is in direct contact with the insulating layer through extrusion molding and is integrated with the tear-resistant layer. As the insulating layer is provided with the tear-resistant layer, and the tear-resistant layer and the sheathing layer are integrated, the lead wire has better wrapping compactness and superior tear resistance and distortion resistance, as well as favorable flexibility, waterproofness, corrosion resistance, pressure resistance and refractability.
Description
Technical field:
The utility model relates to the electric wire field, relates in particular to a kind of tear-proof type silicon rubber insulation motor lead wire.
Background technology:
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes in the world first electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.
Every layer of cover layer of original cable all is the roundness that as far as possible guarantees inside and outside wall, guarantees the structural compactness of cable.In the applied environment of reality, cable twisted or during stretching action, cable core is often easily broken, useful life is short.
The utility model content:
For the prior art problem, the purpose of this utility model provides a kind of tear-proof type silicon rubber insulation motor lead wire, be applicable to ac rated voltage 1.14kV and following F level, H class F insulation machine and electrical equipment lead wire, compact conformation, tear resistance, warp resistance superior performance.
The technical solution of the utility model is as follows:
Tear-proof type silicon rubber insulation motor lead wire, comprise alloy conductor, the described alloy conductor outside is enclosed with flame retardant coating, silicone rubber insulation layer successively, it is characterized in that: described silicone rubber insulation layer outer wall is provided with one deck high carbon alloy silk and weaves webbed tear resistant layer, the outer extrusion moulding of tear resistant layer has restrictive coating, and protective cover material directly contacts with insulating barrier through extrusion moulding and becomes one with tear resistant layer.
Described tear-proof type silicon rubber insulation motor lead wire is characterized in that: described flame retardant coating material adopts the wrapped formation of synthetic mica tape, and the wrapped rate of putting up is not less than 88%.
The utility model has the advantages that:
The utility model is provided with tear resistant layer at cable insulation, tear resistant layer and restrictive coating become one, compactedness is better so that cable coats, tear resistance, warp resistance superior performance, simultaneously, has good pliability, waterproof, corrosion-resistant, withstand voltage properties, fire resistance.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Tear-proof type silicon rubber insulation motor lead wire, comprise alloy conductor 1, alloy conductor 1 outside is enclosed with flame retardant coating 2, silicone rubber insulation layer 3 successively, silicone rubber insulation layer 3 outer walls are provided with one deck high carbon alloy silk and weave webbed tear resistant layer 4, tear resistant layer 4 outer extrusion moulding have restrictive coating 5, protective cover material directly contacts with insulating barrier 3 through extrusion moulding and becomes one with tear resistant layer 4, and the thickness of restrictive coating 5 is 1.5～3 times of tear resistant layer 4.
Flame retardant coating 2 materials adopt the wrapped formation of synthetic mica tape, and the wrapped rate of putting up is not less than 88%, so that cable has good fire resistance.
