Paper covered wire of transformer winding coil

Abstract

The invention discloses a paper covered wire of a transformer winding coil. The paper covered wire comprises an enameled wire, an enamel covering layer and a paper cladding layer. The enameled wire ismade of a copper material, the outer end of the enameled wire is coated with the enamel covering layer, and the outer side of the enamel covering layer is coated with the paper cladding layer. The paper covered wire of the transformer winding coil achieves the purpose of insulation stability of a single wire, increases the creepiness, improves the production efficiency, ensures the appropriate size of the wire and is suitable for use by ultra high voltage and high-capacity transformers.

Description

technical field [0001] The invention relates to the technical field of winding wires, in particular to a paper-covered wire of a transformer winding coil. Background technique [0002] In the traditional production, the insulation of a single paper-covered wire is 0.15mm, and a backing paper is added before the single wire combination. When the size of the wire is less than 10cm, the area of ​​the bearing paper is reduced. The insulation requirements of paper-covered wires are very strict. However, in actual production, a single backing paper has a series of problems such as deviation and breakage. To sum up, so I designed a paper-wrapped wire for transformer winding coils. Contents of the invention [0003] The purpose of the present invention is to provide a paper-wrapped wire of a transformer winding coil, cancel the backing paper between the single wires, add a layer of insulation to the single insulated wire, increase the peristalsis at the same time, and ensure that...
