Product Description

Silk-covered wire, also known as yarn-covered wire, refers to the insulating layer made of natural silk or fiber silk (nylon, polyester fiber, natural silk, self-adhesive silk, etc.) wrapped around the wire or enameled stranded wire. Magnet wire.

Most of the silk-covered wires use polyester as the wrapping material, and the biggest feature is that it has direct weldability. There is no need for sand head in use, and it can be directly welded, which avoids the virtual welding caused by uneven sand head and improves the welding quality. Its insulation performance, high frequency performance, heat resistance, etc. are higher than those of natural silk covered wire. The product has been tested many times, and its Q value and inductance value L are higher than or equal to the same type of imported polyester silk covered wire. Polyester silk is a chemical fiber product, it is rich in resources, and its price is 70% lower than that of natural silk. Polyester silk covered wire is a promising electromagnetic wire product.

On the basis of the advantages of enameled stranded wire, silk covered wire has the advantages of scratch resistance and protective insulation layer. UDTC is a double-layer wrapped wire. Compared with USTC, the wire is slightly harder, but it has a small size (0.10mm) , The voltage effect of multiple wires (more than 300) is obvious.

Tip: Due to the difference in the use of winding equipment by customers, such as automatic wire laying machine, semi-automatic wire laying machine, cutting and winding equipment, please inform our company in advance so that we can provide the best solution; due to the limited temperature resistance of the wire, the The company can only provide B-grade (130ºC) and F-grade (155ºC) products temporarily. Colors can be specified to meet the needs of distinguishing windings. The default silk material is polyester.
