Condenser bushings made of Oil Impregnated Paper (OIP) have been the dependable mainstays of the high voltage transmission sector for many years. The inner workings of these bushings are examined in this article, along with information on their materials, applications, and construction.
Core Design: An OIP bushing has a well carved core at its center. Renowned for its exceptional insulating capabilities, kraft paper is tightly coiled around a central conductor. Aluminum foils are shrewdly placed within the layers of paper at predetermined intervals. As a result, the core becomes covered in a network of small capacitors.
Capacitive Grading: It's not by accident that these metal foils are where they are. It adheres to the capacitive grading principle. Engineers are able to regulate and reduce the strength of the electric field inside the bushing by precisely placing the foils.
Oil Impregnation: After the core is built, it goes through a crucial procedure called processed transformer oil impregnation. By filling in any gaps in the paper, this oil improves its insulating qualities and fortifies the bushing against electrical breakdown.
Durable Housing: A sturdy exterior casing, usually made of porcelain, shields the center. Porcelain is a great option as it
High dielectric strength: The capacity to withstand electrical failure.
Weather resistance: enduring challenging outdoor conditions.
