Yes, enamelled wire is indeed insulated. Enamelled wire, also known as magnet wire or winding wire, is a type of wire that has a thin layer of insulation coating applied to its core conductor. The insulation is typically made of a varnish or enamel material.

The purpose of the insulation is to provide electrical insulation between the wire's core conductor (usually made of copper or aluminum) and its surroundings. This insulation layer helps prevent short circuits and electrical leakage when the wire is wound into coils or used in electrical applications.

The enamel insulation used in enamelled wire has specific electrical and thermal properties that make it suitable for different applications. The insulation material may vary, such as polyester, polyurethane, polyamide, or other types of enamel, depending on the requirements of the specific application.

The insulation on enamelled wire allows it to be used in a wide range of electrical devices and applications, including motors, transformers, solenoids, and various other electrical coils and windings.
