VL Medium Voltage Vacuum Circuit Breaker
VL medium voltage vacuum circuit breaker is a perfect combination of AEG's reliable vacuum arc extinguishing chamber R&D and manufacturing technology, as well as advanced operating mechanism R&D, design and production technology.
VL vacuum circuit breaker fully comply with GB, DL and IEC standards, can be widely used in energy, infrastructure, industrial, commercial and civil construction in the field of medium voltage power distribution system protection and control, especially for newly-built or renovated in medium voltage substation, as well as for various properties of the occasion of load and frequent operation.
• High performance vacuum arcing
- One-time sealing and discharging process, greatly simplifying the manufacturing process, improving the reliability, stability and consistency of products
- Longitudinal magnetic field arc extinguishing technology, increase the number of breaking, strong arc extinguishing ability
- High quality bellows, enhanced air tightness, reliability, longer life
• Epoch-spanning ASP cementing pole column
- Innovative application of new thermoplastic insulation shell, establishing a new environmental standard, can be fully recycled
- Weight reduction, higher toughness, impact resistance, corrosion resistance, low temperature resistance
• Newly developed monostable permanent magnet mechanism
- Simple structure, small volume, compared with spring, electromagnetic mechanism, the number of parts reduced by 70%
- Magnetic material stable performance, no mechanical wear, truly achieve long life and maintenance-free, fully overcome the mechanical failure
- Stably keep the state of split and close, avoid the occurrence of closing bounce
• Leading technology spring operating mechanism
- Gal-II stand-alone module spring operated mechanism reduces the number of parts by 20%, mechanical life up to 60,000 cycles
- Excellent surface protection treatment to ensure the reliable operation of the mechanism in all kinds of harsh environments
- Self-smooth bearing with special requirements ensures long life and maintenance free of GAL series mechanism
• High salt spray resistance black zinc chassis car
- The chassis adopts the industry's most advanced black zinc plating process, and the salt spray test lasts for 500 hours
- Optional electric hand car, electric control hand car in and out, to meet the needs of remote calibration, testing, control, greatly ensure the safety of personnel
