Tests have shown that the quality of a high-voltage insulation is influenced by the type and quality of the mica paper used. A homogeneous and fine distribution of the mica scales as given in the calcined mica paper results in a higher dielectric strength compared to uncalcined mica paper. Other contributing factors are the carrier used, the type of application method employed, and the widths of the tapes, all of which can have a major effect on the electrical strength. Taking this into account, producers and users of high-voltage insulating materials may develop and select the optimum quality for a given insulation design requirement.<>

A description is given of SAMICAFILM, a new generation of conductor tapes developed by taking the favorable parameters of existing tapes and improving them using the latest available technological products. The material shows outstanding electrical and mechanical properties and increased stability against corona discharges. In addition, it offers important advantages to the user during the coil manufacturing process, due to its unique polymer coating on the surface. Significant time, and therefore cost, savings are possible in the production process by using SAMICAFILM with bond-coat on the outside of the polyester film.<>

Just-in-time/total quality control (JIT/TQC) is a proven, practical process that attacks waste. Any activity which does not add value to the product is considered wasteful. Reducing waste increases customer service, reduces costs, and improves quality. When a company has installed an aggressive, ongoing ability to improve its operations, it has created a competitive weapon. It is pointed out that JIT needs TQC. The major thrust of JIT is to identify problems; it highlights the barriers and constraints that are causing waste. TQC corrects them. Without an effective means of overcoming the barriers and constraints, JIT would simply pile up missed opportunities. TQC needs JIT. JIT derives the problems for TQC to attack. The principle and techniques of JIT/TQC are presented, and the change process is described.<>

The results of research into charge storage and its decay are reported for aromatic polyamides which are high-temperature dielectrics. Both thermal poling and corona charging techniques are used. Thermal poling is also carried out at various electric fields and TSD (thermally stimulated discharge) currents are measured by varying several parameters, such as the heating rate, material thickness, and storage temperature. The activation energy for the release of charges is determined by the plots of current and reciprocal of the temperature. The TSD current shows a peak at 135 degrees for a rate of heating of 1 K/min and shifts to a higher value. The charge released to the external circuit is proportional to the poling field. The relaxation time for the delay of charges has been measured by a new experimental procedure, and it is concluded that the material shows dipolar relaxation at 135 degrees C. A positive corona discharge in a point plane gap in air at atmospheric pressure is used for corona poling.<>

The major health and environmental issues impacting the core businesses of the electrical insulation industry over the next several years are examined Issues discussed include the new Clean Air Act, new Occupational Safety and Health Administration (OSHA) rules, waste management, and global influences. It is concluded that successful business in the 90s will build health and environmental issues into their development plans, because such issues usually dictate where products can be manufactured, sold, and used. Only by developing an internal product stewardship program will a business be able to effectively address the regulatory issues it faces.<>

While many are still only thinking about how best to export products from a US manufacturing base, a few have ventured to sell technology to maximize the return of their total assets.

Electrical-grade insulating tapes, pressure-sensitive adhesive (PSA) tapes that consist of an electrically insulating backing and bonding adhesive are discussed. Electrical grade applies to insulating tapes that are manufactured by processes which minimize or eliminate contaminants that may cause electrolyte corrosion. Insulating tapes are constructed of materials which balance the electrical and mechanical requirements of a specific application. The tapes must remain physically and chemically stable in the presence of heat, humidity, and electrical stress. In selecting the appropriate pressure-sensitive adhesive tape for use in a component assembly process, the design engineer must assess the criteria and functional performance of that tape in the application.<>
