Short Description:

This Litz wire is a customized ultra-fine wire, which is twisted by 28 ultra-fine enamelled copper wires with a diameter of only 0.025mm.

The wire uses OFC(oxygen-free copper) as the conductor, the advantage of this material is that it has stronger electrical conductivity.

This unique design makes litz wire unique in its advantages and uses in the market. Not only that, the largest outer diameter of the litz wire is only 0.183mm, and it also has the characteristics of a minimum withstand voltage of 200 volts.

Advantage

The ultra-fine wire diameter of Litz wire is one of its great advantages.

Compared with other traditional wires, Litz wire has a higher fineness and can be more easily adapted to precision needs. Whether in electronic equipment, medical equipment or other high-precision fields, Litz wire can provide reliable and efficient connections.

The Litz wire's ultra-fine strand design provides the perfect balance between softness and strength. This allows the litz wire to bend freely in tight spaces without breaking or being damaged.

For engineers and technicians, this means that they can route and connect circuits more easily and improve work efficiency. Not only that, but the withstand voltage of litz wire is also one of the highlights of its performance.

The minimum withstand voltage of 200 volts makes it very suitable for use in high voltage environments. Whether it is in household appliances, automotive electronic systems or other occasions that need to withstand high pressure, Liz wire can stably transmit power signals. 

Application

The uses of litz wire are wide and varied. In the field of electronic equipment, Liz wire can be applied to the internal connection of equipment such as mobile phones, tablet computers, cameras and audio equipment.

In the field of medical devices, Litz wire can be used in high-precision medical devices such as cardiac pacemakers, nerve electrical stimulators and implantable devices in the body. In addition,Litz wire is widely used in aerospace, automotive and industrial fields.
