Abstract
The utility model discloses a silk-covered wire, relating to a silk-covered wire applied for a generator wire, a motor winding and the like. The inner layer of the silk-covered wire is a copper core; an enamel covering is coated on the copper core; and a polyester and glass sintered layer entwisted by polyester yarns and glass fibers is arranged outside the enamel covering. The polyester and glass sintered layer is arranged outside the enamel covering, and due to the feature of high strength of the polyester yarns and glass fibers, the silk-covered wire has the characteristic of high mechanical strength and can satisfy the requirement in the winding process of the motor.
Description
Technical field
The utility model relates to a kind of silk-covered wire, relates in particular to a kind of silk-covered wire that is applied to generator line, motor winding etc.
Background technology
Because mechanical strength can cause insulating barrier to break inadequately, common silk-covered wire product can not satisfy instructions for use to common enamel silk-covered wire in the generator winding process.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of mechanical strength height, free of contamination silk-covered wire.
The technical solution of the utility model is: internal layer of the present utility model is the copper core, and the enamel-cover layer is established in the outsourcing of copper core, and enamel-cover layer peripheral hardware washed the glass sinter layer by what dacron thread became with the glass fiber alternate lay of stranding.
Described enamel-cover layer comprises inside and outside two-layer, and internal layer is the heat-resistant polyester layer, and skin is a polyimide layer.
The thickness of described enamel-cover layer is not more than 14.
The utility model enamel-cover layer peripheral hardware washed the glass sinter layer, utilizes the high-intensity characteristics of dacron thread and glass fiber, makes silk-covered wire of the present utility model have the high characteristics of mechanical strength, satisfies the needs of motor winding process.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that copper core, 2 is that heat-resistant polyester layer, 3 is that polyimide layer, 4 is for washing the glass sinter layer among the figure.
Embodiment
Internal layer of the present utility model is a copper core 1, and the enamel-cover layer is established in 1 outsourcing of copper core, and enamel-cover layer peripheral hardware washed glass sinter layer 4 by what dacron thread became with the glass fiber alternate lay of stranding, described enamel-cover layer comprises inside and outside two-layer, internal layer is a heat-resistant polyester layer 2, and skin is a polyimide layer 3, and the thickness of described enamel-cover layer is not more than 14.
Through testing: silk-covered wire of the present utility model is compared with common silk-covered wire, and the data of contrast are as follows:
| Comparative run | Common enamel-cover silk copper-clad lenticular wire | Dacron glass yarn bag sintering copper flat wire |
| Thickness of insulating layer | 0.30mm more than | 0.23mm |
| Voltage | 2000V | 2500V |
| Crooked | 10a | 4a |
| Temperature index | 155℃ | 180℃ |
| Chemical property | Do not use | 1H |
Claims (3)
1. silk-covered wire, internal layer is the copper core, and the enamel-cover layer is established in the outsourcing of copper core, it is characterized in that, and enamel-cover layer peripheral hardware washed the glass sinter layer by what dacron thread became with the glass fiber alternate lay of stranding.
2. silk-covered wire according to claim 1 is characterized in that, described enamel-cover layer comprises inside and outside two-layer, and internal layer is the heat-resistant polyester layer, and skin is a polyimide layer.
