New oil-filled apparatus bushings

摘要

FOR 32 YEARS, oil-filled bushings have been applied to transformers and oil circuit breakers. Although these bushings have an excellent service record, recent trends in electric apparatus have made improvements necessary. A new line of oil-filled bushings has been developed which meets the requirements of hermetic sealing, low-cost maintenance, high mechanical strength, reduction in size and weight, and also provides ease of installation and storage. These bushings meet AIEE and NEMA (National Electrical Manufacturers Association) standards and are designed to meet the needs of modern apparatus.
