Vacuum Switchgear Ratings - Trayer Engineering Corporation

Special stainless steel braze welding in which it is not necessary for stainless steel to be plated with Nickel therefore the quality of welding is high and steady as well reliable, meanwhile, the rate of leaking air is low. Special stainless steel features in strong capability to resist the salt mist, which can be applied in wide areas.

Stainless steel is characterized by high tensile resistance, tactility and impact resistance. Special ceramic metallization format and advanced ceramic metallization technical guarantees the air tightness of products and high intensity of tension,that is, the minimum intensity of tension reaches Mpa.

Introduction of Vacuum Switchgear and its Driving Mechanism

Import the most advanced metallization equipment to ensure the conformity and rate of finished products of ceramic metallization technical. Improved inspection methods of ceramic and metallization strength ensures the metallization quality of ceramic shell being stable and reliable in the of integrated tube. The technology eliminates necessity for component welding, reduces the work of man power, therefore the simple technical ensure the stability of products quality accordingly.

It causes rapid vaporization of the contact surface. The interruption of the arc is possible if arc remains in diffused state.

Consistent portfolio – for voltage levels up to 24 kV

Manufactured, assembled and tested all in the same sophisticated facility, SecoVac is the product of state of the art manufacturing processes assured by ISO and ISO certification. Closed Door Racking : The most critical element of your distribution equipment is the vacuum circuit breaker. Switch complete with controls, accessories and terminations Cables not included. All switches, mechanism and bus work sealed within a corrosion-resistant series stainless steel enclosure in an inert SF6 environment. Download documentation. Service intervals would differ between different manufacturers and is further dependant on the operational usage of the equipment.

If it is quickly removed from the contact surface, the arc will be re-strike. Arc extinction in vacuum breakers is greatly influenced by material and shape of the contacts and the technique of considering metal vapor. The path of the arc is kept moving so that temperature at any one point will not be high.

Product Features

After the final arc interruption, there is rapidly building up of dielectric strength which is peculiar of the vacuum breaker. They are suitable for capacitor switching as it will give a re-strick free performance. The small current is interrupted before natural current zero, which may cause chopping whose level depends on the material of contact.

04 MV Air Insulating Switchgear (AIS)

Vacuum offers the utmost insulating strength. So it has extreme superior arc quenching properties than any other medium. The vacuum circuit breaker is today recognized as most reliable current interruption technology for medium voltage switchgear.

Presto Switchgear Private Limited

In medium voltage switchgear application, medium voltage vacuum switchgear ranges from 3 to 36 KV. Now days, vacuum interruption technology, in medium voltage application, dominates, air, SF6 and oil technologies. Since, vacuum circuit breaker is more safely and reliably operated. Researches and investigations in the early s allow the employment of vacuum switching technology for generator.

It requires minimum maintenance compared to other circuit breaker technologies. The technology is mainly suitable for mainly medium voltage application. For higher voltage vacuum technology has been developed, but it is not commercially feasible. Vacuum circuit breakers are used in metal clad Switchgear and also in porcelain housed circuit breakers.
