Porcelain is a key component used in the construction of electrical components throughout the electrical grid, including high voltage bushings. It is non-hydroscopic and will not enable mold to develop in high humidity environments. In addition, porcelain a non-organic material so it will not deteriorate over the life of the product.
The PCORE oil-free PRC® bushing was recently developed to provide an option to customers who are looking to reduce oil-filled equipment in substations. The oil-free solution provides a more environmentally friendly bushing with the same great benefits.
