HVWW® – High Voltage Winding Wire

Innovating The Future Of Electric Vehicles

Essex Solutions offers a HVWW® product designed for use in the automotive industry. Our technology benefits customers demanding lighter weights to achieve smaller and more efficient traction motors.

High voltage creates high heat. In the electric vehicle industry, heat resistance, flexibility and repeated stress are ongoing obstacles to magnet wire performance. Our engineers accepted the challenge to perfect every design element for an exceptional product.

Specially formulated to provide outstanding resistance to Partial Discharge Inception Voltage (PDIV) and Corona effect, HVWW® is suitable for a variety of key applications exhibiting high flexibility and property retention maintaining product performance even after the winding operation.

Reduced Carbon Impact

HVWW® is the best choice for customers in the automotive industry that are looking to reduce their carbon impact. Both the production process and material construction result in fewer carbon emissions when compared to traditional magnet wire.

Essex is committed to lessening our own carbon footprint through a holistic sustainability initiative, Vision 2030: A Sustainable Future, Our Driving Force.

The Power of Two Pioneering Industry Leaders

HVWW® was initially developed in 2017 during a joint venture between Essex in Germany and Furukawa Electric in Japan. With the growth of xEVs, the goal was to support the high-performance demands within the European automotive market. Due to the success of this partnership, Essex has since expanded the technology to the global market.

In 2024 Essex bought out the global joint venture, rebranding the magnet wire business Essex Solutions. With an expanded global presence and streamlined operations, the company is well-positioned to meet the evolving needs of its customers and drive future technologies forward through the production of HVWW® and a comprehensive suite of products.

HVWW® Outperforms Mono-Layer (PEEK)

HVWW® features a unique product construction of heat-resistant enameled copper wire over which an extruded resin layer is added, resulting in a magnet wire product that is highly customizable and unparalleled in performance.

HVWW® has excellent windability due to its highly flexible design, durable insulation, and excellent adhesion between the Copper, PAI, and PEEK layers which improves the installation process. It will be able to increase the PDIV to meet any requirement of motor driving voltage and environment condition due to increase in the coating thickness.

For performance and reliability in electric vehicle applications, the choice is clear.
