Leybold vacuum pumps and solutions for transformer drying and production.
Vacuum pumps and systems for the electrical industry
Electricity is the literal lifeforce of modern society – powering everything from small home microwaves to large-scale industrial machinery. To ensure stable electricity generation, transmission and distribution, the infrastructure is vital. High voltage power transformers, distribution and instrument transformers, bushings, transformer oil, power capacitors and SF6-insulated circuit breakers are critical components to provide stable power transmission. All of them require vacuum drying during production to ensure a high insulation strength.
For the producers of these kinds of equipment, the right choice of vacuum pumps and vacuum systems is from utmost importance. Good vacuum products can handle the challenges of these drying processes and can ensure a stable and seamless operation with optimized cost of ownership. At the end, this also guarantees that the required high product quality is produced.
