Vacuum Circuit Breaker Series

Application of IndoorsF6 Circuit Breaker SF6 circuit breakers are a perfect upgrade foraging power infrastructure,especially in situations where the insulation of motors and cables is sensitive to dielectric stress.Indoor SF6 circuit breakers.with their compact footprint and top-notch insulation performance,are right at home in space-constrained indoor substations and distribution rooms.They stand up well to frequent operation,ensuring the stable running of critical equipment and slashing maintenance downtime.Furthermore,their environmentally friendly characteristics make them an ideal fit for indoor locations with strict environmental requirements,helping to build a safer and more reliable power distribution network. LYHM4 medium voltage circuit breaker uses sulfur hexafluoride (SF6) gas as arc extinguishing and insulating medium. SF6 gas has smooth breaking characteristics, and there will be no interception phenomenon when breaking the current, and no operating overvoltage will occur. This excellent characteristic ensures that the circuit breaker has a long electrical life. And the impact on the equipment during operation, the dielectric level and thermal stress will not be affected.

Their compact dimensions and limited weights make the Power Cube type PB/F fixed parts the ideal solution for replacing fixed circuit breakers with withdrawabie circuit breakers, for retrofitting activities and for upgrading obsolete switchgear to the new Standards. The Power Cube type PB/F fixed parts are factory-assembled and tested and, where applicable, comply with IEC 62271-200 and IEC 62271-1 Standards. The fixed parts allow construction of arc proof switchgear - classification LSC2B-PM IAC BFLR or LSC2B-PM AFLR according to IEC 62271-200 (in accordance with IEC 62271 Standards for general characteristics).

Whether customers choose air-insulated or gas-insulated switchgear depends on the application as well as on some aspects such as the initial investment cost, total cost of ownership, available space and location (ie. altitude, dust, etc.). We encourage you to get in touch with our sales experts to get the right advice. The GIS circuit breaker is used for gas insulated switchgear, uses splint structure. Its easy to install, reliable breaking performance, long mechanical life and no maintenance. It is substitute for vacuum circuit breaker used in inflatable cabinet. The product performance met standard of GB1984-2014 E2-M2-C2 circuit breaker requirement.

Vacuum circuit breaker is the most commonly used type of high-voltage circuit breaker, mainly divided into two kinds of indoor and outdoor. We mainly focus on indoor vacuum circuit breakers. (Indoor circuit breakers: High-voltage circuit breakers that do not have the performance of protection against wind, rain, snow, ice and dense frost, etc. and are suitable for installation and use inside buildings.) The vacuum circuit breaker is named after its interrupting medium and the insulating medium of the contact gap after interrupting is high vacuum; it has the advantages of small size, light weight, suitable for frequent operation and interrupting without maintenance, and is more popularly used in the 3kV-40.5kV distribution network. The components of vacuum circuit breaker are vacuum interrupter, electromagnetic or spring-operated mechanism, bracket and other parts. Vacuum interrupter is the core component of vacuum circuit breaker, its main role is, through the excellent insulation of the vacuum inside the tube to make the medium and high voltage circuit cut off the power can quickly extinguish the arc and suppress the current to avoid accidents and accidents.

VSG/C-40.5 Series Side Mounted Vacuum Circuit Breaker is a new type of three phase 50Hz according to the unique design concept and combined with the market demand and development, the rated voltage of indoor switchgear 40.5kV, it can be provided to industrial and mining enterprises, power plant and substation as the control and protection of electrical equipment, and is suitable for frequent operation.

VBI-12 medium voltage vacuum circuit breaker is a kind of indoor medium voltage switch equipment with 50Hz/60Hz three phase AC 12kV rated. voltageVBI type vacuum circuit breaker conforms to national standard GB1984-2003 HV Vacuum Circuit Breaker, JB3855-1996<3.6-40.5kV indoor AC high voltage vacuum circuit breaker>, DL/T403-2000<12kv-40.5kv HV vacuum circuit breaker ordering technical conditions>, and IEC62271-100:2001 high voltage AC circuit breaker relevant regulations.VBI high voltage vacuum circuit breaker is used for 12kv or 24kv power system indoor switching ecuipment

VBI-12 Indoor High Voltage Vacuum Circuit Breaker is three-phase AC 50Hz, rated voltage of 12KV indoor device. For industrial and mining enterprises, power plants and substations as electrical equipment control and protection purposes, and for frequent operation of the place. The VBI series indoor vacuum circuit breaker is a new generation of intelligent vacuum circuit breakers.

The VBI series indoor vacuum circuit breaker is a new generation of intelligent vacuum circuit breakers. Its live components, including the high-performance vacuum interrupter and upper and lower outgoing terminals, are encapsulated in epoxy resin post terminals. This design helps prevent contamination on the surface of the vacuum interrupter, enhancing its insulation properties, mechanical stability, and extending its operational lifespan. The operation mechanism of VBI-24 side mounted type vacuum circuit beaker is used spring to storage energy,which can be operated by two ways,manual or electrical.The characteristics are accordance with GB1984-89 ,JB3855-96<10kv Indoor High Voltage Vacuum Circuit Breaker General Technical Specifications>,Relevant Provisions of IEC56 standard.
