( Brand: Ge ), ( Manufacturer Part Number: 9CE5A51 ), ( Part Type: Oil Capacitor )
The General Electric 9CE5A51 is an antique, high-voltage capacitor that was once a vital component in various electronic applications, particularly power supplies and radio equipment, during the mid-20th century. This specific capacitor model, the 9CE5A51, was manufactured by General Electric's Pyranoid Division, known for its production of oil-filled capacitors.
This antique capacitor features a cylindrical shape with a diameter of approximately 3 inches (7.6 cm) and a height of around 5 inches (12.7 cm). Its primary function is energy storage in high-voltage electrical circuits. This model has a voltage rating of 2000 volts, which signifies the maximum electrical potential difference it can withstand without breaking down or causing a short circuit.
The vital element of this capacitor is its construction. It is an oil-filled, electrolytic capacitor, designed to utilize a dielectric medium in the form of insulating oil, ensuring reliable operation even at high voltages. The body of the capacitor is made from a toughened paper or rated cellulose material, and a thin metallic foil is rolled into multiple layers, placing it inside. These layers form the capacitor plates, and electrolyte is used to separate the plates, permitting the storage of charge through the electrochemical reaction.
This antique capacitor from General Electric is enclosed in a porcelain case, historically a common material for insulation in older electronic components. The case also has a vented design with a buried capacitor leak detection fuse, essential for monitoring and maintaining the oil level and ensuring safe operation. An isolation transformer is usually required for safe operation.
Making this capacitor even more retro is its anodized aluminum terminal caps. These caps protect the electrical connection between the capacitor and other components while aesthetically adding to its vintage charm. The terminals themselves are made with copper, and the (wires) may be made from silver-plated copper or tin-coated copper.
Though it is widely accepted that new, modern capacitors should be utilized for current applications due to their superior performance, the historical significance of these antique capacitors cannot be overlooked. The General Electric 9CE5A51, an exemplary specimen from Pyranoid's impressive past, holds great value for collectors, hobbyists, andRETRO enthusiasts. It not only showcases the nostalgic allure of vintage electronics but also offers insight into the evolution of capacitor technology.
