4 FOCUS ON QUALITY & INNOVATION To bring the customers the most efficient solutions in winding wire and CTC. HIGH QUALITY Essex employees are strongly focused on delivering to customers the right products at the right time, with the lowest impact on the environment. The Essex plants are equipped with state of the art equipment and are operating in compliance with norms ISO TS16949, ISO 9001, ISO and according to international standards. Furthermore, a robust continuous improvement program fine tunes the processes, the quality level and the flexibility of the plants year after year. INNOVATION IS KEY To face the challenge of our customers looking for a better power efficiency of their products, a dedicated R & D team for transformers and generator wires is working alongside them. New enamels, new wire design, innovative constructions, the R & D team will find the best solution to improve the performance of the customers product.

5 A FULL INTEGRATED PROCESS Because raw material quality and performance of enamels are key. VARNISH INTEGRATION Essex is the only European winding wire producer also manufacturing its enamels. First, it guarantees the perfect adaptation of the enamel characteristics to the Essex winding wire production line to deliver the best quality and efficiency. Besides, Essex engineers from the winding wire and enameling departments team up continuously to define the best and innovative solutions for the customers.

14 A WIDE RANGE OF SPECIALTIES To answer the needs of specific solutions. CORDEX Cordex CTC is a special Transposed Cable without paper insulation. It is wrapped with a transformer oil resistant polyester monofilament. Different types of Cordex are available. PERFORATED PAPER This product gives excellent heat dissipation and is suitable for epoxy application with radial or concentric Bond. The cable is wrapped with perforated aramide paper. DIAMOND WRAP This covering currently consists of two opposing wraps of aramide paper arranged to allow free oil flow through the CTC strands for cooling purposes. A linear protection crepe paper is normally inserted on the underside of the cable.
