The present invention relates to an insulating tape for winding around a conductor. The insulating tape is provided with a fabric that acts as a support. A high dielectric material is provided on a woven fabric that includes a warp composed of a relatively coarse yarn and a weft composed of a finer yarn formed in a coarse mesh. The warp and the weft are guided in the winding direction. Warp yarns are provided with a low yarn density. Thereby, the weight of the surface matches the weight of the surface of the fine mesh woven fabric in which the warp and the finer weft are made of finer woven yarn. Greater edge tear strength is obtained for fine mesh fabrics. This strength is obtained with coarser yarns that are derived at lower yarn densities and used in warps.

No. 974B discloses an insulating tape according to the preamble of claim 1.
The insulating tape comprises a mechanically fixed support consisting of a glass silk fabric, which usually has a weight per unit area of 20 to 40 g / cm 2 , and a weight per unit area, which is the number of weights per unit area of the fabric. It comprises a layer of a highly dielectric material, for example fine mica or mica paper, which is applied to the fabric. The weight ratio of the highly dielectric material determines the quality of the insulation obtained from the insulating tape, in particular the strength of the breakdown.

tex (mass per 1000 m of yarn length) is formed by warp and weft from a woven yarn, whereas a heavier woven fabric has a woven weft with a yarn weight of about 5.5 tex, It has a warp of coarser weave yarn weighing about 11 tex.

ープからなる同じ厚みの絶縁破壊の強さよりも小さい。[0004] The lighter fabric has a tensile strength in the warp direction of about 70 N / cm, while the heavier one has a tensile strength of about 130 N / cm. When forming the insulation, the warp is oriented in the winding direction. Since the tensile strength of the heavier fabric in the winding direction is larger than that of the lighter fabric, the insulating tape including the heavier fabric can be wound at a higher speed without breaking the tape. In any case, because of the higher weight ratio of the fabric in the insulating tape, the strength of the dielectric breakdown is less than the strength of the same thickness of the insulating tape comprising the lighter fabric.

Formed from an insulating tape with a light glass fabric. Due to the low yarn density of the relatively coarse weave yarn used in the warp of the fabric with the insulating tape according to the present invention, the woven portion of this tape is maintained at about the same level as that of the previously described insulating tape with a light glass fabric. You. In addition, the thickness of the coarser yarn used for warp is
It does not adversely affect the dielectric properties of the insulating tape according to the invention, or the resulting insulation. One reason for this is that even if the weight of the yarn is doubled, the thickness of the diameter of the yarn is only 1.4 times the thickness, and another is that the yarn having a large thickness during winding due to the low yarn density. Is flattened.

It is mainly characterized in that the warp of coarser yarns can be provided like an insulating tape comprising a heavy fabric woven with a finer mesh. Since the number of warps is small, in the insulating tape according to the present invention, the characteristic of tensile strength of the insulating tape to be wound which is important at the time of winding is higher than that of the insulating tape having a woven fabric of the same weight and having more warp of finer woven yarn. This technical effect is clearly surprising, since it is not too large. However, when winding around conductors having a generally rectangular or square profile, not only the tensile strength but also mainly the edge tear initiation strength has been regarded as important. The warp yarns do not tear together during winding, but advance from one end of the tape that has been wound onto the conductor for each yarn. Therefore, the strength of the individual warps is particularly important for the tear strength of the insulating tape. The use of a slightly, but relatively thick, and thus tear-resistant warp resulted in a woven construction that met the demand for a light woven that was resistant to the onset of edge tearing.

Due to such high porosity, it becomes very easy to impregnate the insulating tape wound with the impregnating resin, and the time is shortened.

になる。DETAILED DESCRIPTION OF THE INVENTION Three insulating tapes were made for winding around a conductor having a rectangular profile. Each of these insulating tapes comprises as support a glass silk fabric of various structures and a mica paper bonded to a fabric weighing 180 g / m 2 per unit area. Each of these three insulating tapes was cut from an insulating tape web having a width of about 1 m so as to have a width of about 25 mm in the warp direction (winding direction). Then, for these three insulating tapes, the tensile strength and the edge tear initiation strength (the tearing strength of the insulating tape supported by the edge of the insulating tape and guided obliquely to one end of the conductor) and Porosity (after Gurley) was determined. These amounts are important in winding the conductor and impregnating the wound conductor with the impregnating resin. The structure of the glass silk fabric belonging to the three insulating tapes and the aforementioned properties of the three tapes are summarized in the following table. Insulating tape 1 (prior art) 2 (prior art) 3 invention Weight per unit area g / cm 23 33 24 Weight of warp tex 5.5 11 11 Weight of weft tex 5.5 5.5 5.5 Thread density, warp 27 cm / cm 16 Yarn density, per 1cm of weft 15 11 10 Tensile strength in the warp direction N / cm 80 140 104 Edge tear initiation strength N 8 16 8 Porous, glass side s / 100ml 100 180 100 In contrast to the insulating tapes 1 and 2 of the prior art, the insulating tape 3 has a lower warp density and a lower yarn density. Thus, a coarse mesh woven fabric having a weight per unit area corresponding to the weight per unit area of a fine mesh woven fabric by the insulating tape 1 including warp and weft of finer woven yarns is obtained. However, in contrast to this fabric, the insulation tape fabric has twice the height of the edge tear initiation strength. The fabric of the insulating tape 2 has a relatively high edge tear initiation strength, but is considerably more so that the insulation obtained with it has a considerably lower dielectric strength than the correspondingly obtained insulation from the insulating tape 3. It becomes heavy.

れる。In order to prevent the weight per unit area from becoming excessively large and to prevent the thickness of the woven fabric having a high edge tear initiation strength from becoming excessively large, for example, the weight of the main woven yarn is about 2 pairs. It is preferable to use one that is 1. If the weight per unit area of the fabric is between 20 and 28 g / cm 2 , the yarn density of the warp should be between 10 and 20 yarns per cm. The insulating tape 3 is exposed to an edge tear initiation force of 12-18N.

浸できるため、生産時間が大幅に短縮される。Commercial Applications As can be seen from the table, the porosity of the insulating tape 3 is almost twice that of the prior art and comparable in terms of weight per unit area. Therefore, when forming an insulated conductor after winding it around the conductor, it can be impregnated very quickly with the impregnating resin, greatly reducing the production time.

ープを用いて、高速の巻き付け速度で導体への巻き付けが可能となる。Further, the insulating tape according to the present invention has excellent dielectric properties and a high resistance to the initiation of edge tear because of the low proportion of the woven fabric. Therefore, using the insulating tape according to the present invention, the conductor can be wound around the conductor at a high winding speed.
