Enamelled flat wire, also known as rectangular enamelled wire, is a type of electrical conductor with a rectangular cross - section, coated with an insulating enamel layer. It is widely used in various electrical and electronic applications due to its unique characteristics. Here are the main features of enamelled flat wire:
1. Special Geometric Shape
Rectangular Cross - Section: Unlike round wires, it has a flat and rectangular shape, which allows for more efficient space utilization in winding applications.
Higher Fill Factor: The flat design enables tighter packing in coils, increasing the number of turns per unit area and improving the power density of electrical devices (e.g., transformers, motors, and generators).

2. Excellent Insulation Performance
Enamel Coating: The wire is coated with a thin, uniform layer of enamel (such as polyurethane, polyester, or polyimide), which provides reliable electrical insulation.
Heat Resistance: The enamel can withstand high temperatures (ranging from 130°C to 240°C, depending on the type), ensuring stability in high - heat environments.
Mechanical Protection: The coating also resists abrasion, moisture, and chemical corrosion, extending the wire's service life.

3. Superior Electrical Conductivity
High - Purity Conductors: Typically made from copper or aluminum with high electrical conductivity, it minimizes power loss and ensures efficient current transmission.
Low Resistance: The large cross - sectional area (for a given wire gauge) reduces ohmic resistance, making it suitable for high - current applications.

Pacific Wire & Cable Co., Ltd. (hereinafter referred to as Taidian Group) was established on April 14, 1950, providing a full range of wire and cable products, including: power cables, communication cables, optical cables, bare copper wires, bare aluminum wires, electronic wires, enameled wires, plastics, copper strips. Taidian Group adheres to the concept of honest management of "genuine and undeceiving" in Beiping Times Yongguang Wire Factory, and achieves customer first, leading quality, excellent production, research and innovation, and becomes a pioneer in the wire and cable industry.

In 1964, Taidian Group entered the international market for the first time, and successively set up subsidiaries in Singapore, Thailand, Australia, and both sides of the Taiwan Strait, and established Pacific Wire and Cable (Shenzhen) Co., Ltd. on December 25, 1995, with a registered capital of 16.6 million US dollars, a total investment of 19.6 million US dollars, and 36,000 square meters of self-purchased land. High-quality motors and other products around the assembly, the company obtained 1SO9001, 1SO14001, ISO45001, |SO50001, IATF16949 and other system certification.
