Insulated winding wire

CPC v2.1 Code: 4631

About insulated winding wire

cpc code 4631 covers the production of insulated winding wire, a critical component in the manufacturing of electrical equipment and machinery. This industry plays a vital role in the broader electrical and electronics sector, providing the essential materials needed to construct the coils, transformers, and motors that power a wide range of devices and systems. Insulated winding wire is a fundamental input for a variety of 3812 Electrical industrial apparatus and 3825 Computers and office equipment industries, making it an important contributor to the overall economy.

Production process

The production of insulated winding wire involves several key steps. First, the base wire, typically made of copper or aluminum, is drawn to the desired diameter and then coated with an insulating material such as enamel, polyurethane, or polyvinyl chloride. The coated wire is then wound onto spools or reels, ensuring a uniform and consistent product. Quality control measures are implemented throughout the process to maintain the wire's electrical properties and dimensional accuracy.

Production inputs

The main inputs required for the production of insulated winding wire include the base metal (copper or aluminum), insulating materials (enamel, polyurethane, etc.), and specialized machinery for drawing, coating, and winding the wire. Additionally, the industry relies on a skilled workforce capable of operating the production equipment and ensuring the wire meets industry standards.

Production outputs

The primary output of the insulated winding wire industry is, of course, the insulated winding wire itself. This product is then consumed by various 3812 Electrical industrial apparatus and 3825 Computers and office equipment manufacturers, who incorporate the wire into their own products, such as electric motors, transformers, and other electrical components.
