Overview

SWCC's coated flat bar eliminates the need for dies through wire forming processing. It contributes to improved yield and space savings in busbar manufacturing.

Features

■ Excellent formability with high resistance to bending and torsion
■ Advantageous for welding processes
■ Superior electrical conductivity

Applications

Long busbars connecting devices within BMS requiring complex precision processing

Overview

SWCC's oxygen-free copper is a high-performance oxygen-free copper, optimized through dip forming systems to achieve copper purity of 99.99% or higher (4N) and oxygen content controlled to less than 10 ppm.

Features

■ Minimal copper powder generation during cold forging
■ High ductility and excellent conformability to dies
■ Superior electrical conductivity

Applications

Lithium-ion battery terminals, high-voltage harness terminals

Overview

Increasing the coil's packing density enables smaller, more efficient motors and transformers. Our fine flat wire accommodates a wide range of applications, improves coil magnetic field efficiency, and contributes to smaller, lighter, and more efficient equipment.

Features

■ Enables high coil packing density and high current capacity
■ Excellent frequency characteristics allow production of coils with high magnetic field efficiency
■ Superior insulation at corners achieved through proprietary processing technology

Applications

High-efficiency coils for automotive inductors, converters, ECUs, reactors, etc.

Overview

With the electrification of automobiles, demand for heater devices such as seat heaters and steering wheel heaters is increasing.
We supply highly reliable heater wire made from high-strength enameled wire.

Features

■ High Strength ⇒ Over 3 times that of pure copper, comparable to stainless steel
■ High Conductivity ⇒ 60-90% IACS
■ Excellent Flexural Resistance ⇒ Over 70 times that of pure copper bare wire

Applications

Electrical components such as fine-gauge lead wires, small motors, coils, and heater wires
(Steering wheel heaters, seat heaters, battery heaters)

Overview

Litz wire consists of multiple enameled wires twisted together, with its name derived from the German word "Litz" (meaning "to twist").
SWCC's Litz wire suppresses the increase in AC conductor resistance caused by the skin effect and proximity effect characteristic of high frequencies, thereby preventing temperature rise.

Features

■ Minimizes the increase in AC conductor resistance caused by high frequencies, suppressing temperature rise
■ Enables higher efficiency, smaller size, and energy savings in equipment
■ Excellent flexibility and good winding workability
■ Wire type, number of strands, and wire diameter can be selected as required

Applications

Coils for non-contact power supply, high-frequency equipment, inverters, transformers, motors, heating devices (IH), etc.
