This circuit breaker is a reinforced insulation type, which meets the requirements of the use environment in Class II polluted areas. This circuit breaker has simple structure, strong breaking capacity, long life, complete operation functions, no explosion hazard, simple maintenance, suitable for control or protection switch of power plant, substation and other transmission and distribution systems, especially suitable for breaking important loads and frequently operated places. This product is in accordance with related requirement of GB1984, JB3855, DL403 and IEC standards.

CT68-24 vacuum circuit breaker is an indoor high-voltage vacuum circuit breaker, mainly used in distributed power systems, mines, petroleum, chemical industry, metallurgy, construction, transportation, coal mines and municipalities, as well as in the power supply and distribution systems of urban residential buildings and public facilities and other places. It is widely used to protect high-voltage power equipment from over-current, short-circuit, under-voltage and over-voltage, and can reliably guarantee the safe operation of power equipment. CT68-24 vacuum circuit breaker adopts fully enclosed structure (central type), has good waterproof and moisture-proof performance, and can work under harsh environmental conditions. It has good thermal stability of short-circuit full-load current, strong overvoltage capability and short-circuit breaking capacity. In addition, it can quickly connect wires, cables and other equipment to improve installation efficiency and make site installation and maintenance more convenient. Widely used at home and abroad, CT68-24 vacuum circuit breaker is a high-quality power equipment, known for its reliable performance, excellent quality and long service life.

VBI indoor high-voltage vacuum circuit breaker has reliable performance and is easy to install. It is the best choice for the control and protection of high-voltage transmission and distribution systems. The VBI-40.5 Floor Mounted Vacuum Circuit Breaker is a high-performance, medium-voltage switching device designed for reliable protection and control of electrical systems rated at 40.5kV. Utilizing advanced vacuum interrupter technology, it ensures efficient arc quenching, minimal maintenance, and a long operational lifespan. Ideal for power distribution networks, industrial plants, and substations, this breaker combines robust construction with user-friendly operation.

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
