240℃ Super High PDIV (Low-DK) And Corona-resistance Enamelled Rectangular Copper Winding Wires HEVW-240CL

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. Versatility in Applications
Widely Used in Motors: Ideal for stator and rotor windings in electric motors, where space efficiency and high power output are essential.
Transformers and Inductors: Suitable for high - frequency transformers and inductors, minimizing core losses and improving energy efficiency.
Consumer Electronics: Used in compact devices like laptops, smartphones, and home appliances to save space and reduce weight.

8. Environmental and Safety Features
Lead - Free and RoHS Compliant: Many enamelled flat wires comply with environmental standards, reducing harmful substance emissions.
Flame Retardancy: Some coatings offer flame - retardant properties, enhancing safety in critical applications.

In summary, enamelled flat wire combines efficient space utilization, reliable insulation, and high electrical performance, making it a preferred choice for advanced electrical and electronic designs that demand compactness and durability.
