What is silk covered litz wire?

Silk covered litz wire is a wire whose conductors consist of a enameld copper wire and enameled aluminum wire wrapped in a layer of insulating polymer, nylon or vegetable fiber such as silk.

Silk covered litz wire is widely used in high-frequency transmission lines, motors and transformers, because its insulation layer can effectively reduce current loss and leakage, and can improve the durability and reliability of the line.

Silk covered litz wire also has excellent wear resistance, pressure resistance and oxidation resistance, so it is also widely used in machinery manufacturing, metallurgy, chemical industry and other fields.
Silk covered litz wire and enameled copper wire are both insulated wires, and the difference is mainly in the material and manufacturing method of the insulating layer.

1.The insulation is different: the insulation layer of silk covered litz wire is made of polymer,nylon or plant fiber (such as silk), while the insulation layer of enameled wire is polyurethane paint.
2.The production method is different: silk covered litz wire is wrapped with nylon on the outer layer of enamelled stranded wire, and we can also provide polyester and natural silk. The production process of enameled copper wire is to wind the copper wire on the insulating rod, then coat it with multiple layers of varnish, and make it after several times of drying.
3.Different application scenarios: Enameled copper wire is mainly used in high-frequency transmission lines, motors and transformers, while enameled wire is mainly used in electronic components such as electric coils, inductors and transformers.

Generally speaking,silk covered litz wire is more suitable for working in harsh environments such as high temperature, high frequency, and high voltage than enameled wire. Its insulation performance is better, but the cost is higher.
Enameled copper wire is more suitable for general low voltage and low frequency occasions, and the cost is lower.
