In an increasingly competitive world economy, it has become essential for copper magnet wire manufacturers to obtain good die life and improved product quality at a competitive cost advantage. One of the largest factors relating to excess die wear, die failure and poor product quality is lubricant selection and process control. This paper presents an overview of the lubrication mechanisms in wire drawing, the physical and chemical makeup of wire drawing compounds and a review of testing techniques and process controls for lubricating compounds used to draw copper magnet wire.

Electrical insulating paper and mineral oil form the basic electrical insulation system in much electrical power equipment, including cables, transformers, and switching apparatus. Many facets of the electrical behavior and performance of insulating papers in such systems have been investigated and reported in the past. It is well known that a very substantial increase in dielectric strength is achieved when mineral oil permeates and impregnates insulating paper.

Although 25 % of all major fires are caused by electrical equipment, only a very small percentage can be attributed directly to the cables. They can, and do, overheat when subjected to current overloads or system failures, but adequate circuit protection ensures that only very few fires are started in this way.

New technology in electric motor repair. For the last fifty years, the technology for electric motor repair in the united States has remained virtually unchanged. Nearly all of the electric motor repair companies have been and still are using the same machines and methods that were used when motors first came into existence. These methods have proven to be outdated, wasteful, time consuming and, in most instances, damaging to the electric motor laminations. In the last sixteen years, new technology has given birth to a whole new method of repairing electric motors.

Insulation measurements on high voltage equipment are usually performed using a bridge method, comparing the specimen against a known standard. The measuring process involves adjusting the high voltage level, reading a nullindicator, balancing the bridge, transcribing the readings and eventually analyzing the data. This process has been completely automated by means of a micro-processor and a measuring system suitable for high voltage laboratories or assembly line testing is described in this paper.

To achieve improved efficiency and higher output in both AC motors and generators, an insulation system must be capable of withstanding high volts per mil stress and high operating temperatures. To obtain such performance the development of a new B-staged epoxy resin rich press curable mica paper tape must address several key elements. This paper presents definitions for establishing a Class F resin rich tape system; proposes a new laboratory procedure for producing test specimens; and presents test data on both laboratory specimens and production coils which verify the successful development of a new press curable mica paper tape insulation system for AC motor and generator coils and bar windings.
