What Makes Nomex® Paper Wrapped Winding Wire the Right Choice for Dry Type and Traction Transformers?
If you’ve ever opened up a transformer that’s been running for years without trouble, chances are you’ll find Nomex® paper wrapped wire inside. There’s a reason it shows up in dry-type units, traction transformers, substations, and even oil-filled coils – it just works, an...Read more -
Taped litz Wire for New Energy Electric Vehicles
These days, electric cars are selling really well worldwide. Most new models use 400V or 800V high voltage systems, and taped litz wire is a must-have material for all their electric components. We produce this litz wire with pure copper, wrapped with thin insulating demanded by customer. It wor...Read more -
FIW vs TIW – Which Insulated Wire Is Right for Your Transformer Design?
To begin with, in terms of structure: FIW wire is multi-layer coating. It is made up of multiple coats of insulating varnish, forming a very thick insulation layer which is treated as a single conductor. In contrast, TIW wire( triple insulated wire) is made of three separate layers of insulation,...Read more -
Analysis of Differences between Acetaldehyde Resin and Polyester Coatings in Enamel Copper Wire Applications
Several colleagues were discussing the solution to a enameled copper wire product in the conference room of Tianjin Ruiyuan. Is the enamel copper wire insulation material acetaldehyde resin or polyester? We got the answer after we research. The nature of the insulating varnish used in enamel copp...Read more -
Looking Ahead at Tianjin Ruiyuan Electric’s Future Five Years Through the Lens of “Hot and Cold” Debate
Between Cold and Heat: A Magnet Wire Company’s Magnetic Future The dust of the college entrance exam has just settled, and millions of students and parents are now embarking on another “battle”—filling out university applications. Terms like artificial intelligence, big data, an...Read more -
Why use litz wire in high frequency transformers?
High-frequency transformers are commonly used in new energy and industrial power conversion equipment. Standard solid copper wire loses a lot of power at high frequencies and hurts overall efficiency, which is why we use litz wire to improve transformer performance. These power losses are mainly ...Read more -
Residual Resistivity Ratio (RRR or 3R) Test for High Purity 6N and 7N Copper
In advanced fields such as cryogenics, superconducting magnets, nuclear fusion and high-end audio systems, 6N 99.9999% and 7N 99.99999% copper are one type of widely used material. But how do you truly measure and compare the purity and electrical performance of these materials? The answer lies i...Read more -
