Product advantages
Product advantage
> Leading technology
- Standard anti-corrosion and salt spray environmental plan to meet the stringent environmental requirements of the site
- The components can be equipped with ABB's original HAD/US type ISF6 circuit breaker or VD4-S type vacuum circuit breaker
- SFL-12/24 switchgear with components assembled in China can also be used according to the needs of users
- With perfect and reliable mechanical linkage, interlocking device, fully achieve the "five prevention" function (IP3X)
> Cabinet put oneself in another's position
- The whole is made of 2mm hot dip galvanized plate
- Laser numerical control equipment cutting, drilling, bending, to ensure the processing accuracy
- The exterior is coated with electrostatic epoxy powder, which will not take off paint for 50 years
> Functional units
- Manual and electric operation, remote control function
- Load switch, combination electrical appliances, its installation mode is flexible, can be installed on the left and right side, front, flip
- Two pressure relief holes, cable room and bus room (load switch) at the back of cabinet
> Busbar system
- High quality three-phase tin bus copper bar, high mechanical strength, good heat dissipation
> Processing and assembly
- Dust-free workshop to ensure insulation
- Assembly workers have been trained for at least 6 months
- Use power tools to ensure proper torque for bolting reinforcement
- The copper bus is CNC cutting, punching and bending to ensure the accuracy
- Leybold Helium Mass Spectrometry Leak Detector, Germany -- ensure that the leakage rate of SF6 gas tank is below the national standard
- Computer-controlled equipressure pumping and inflating integrated equipment for vacuum chamber -- to ensure no deformation of gas box and 99.9% purity of SF6 gas
Product parameters
>Conditions of use
- Altitude shall not exceed 2000m
- ambient air temperature not higher than +40 ° C, not lower than -5 ° C (average temperature within 24 hours not higher than +35 ° C)
- The humidity of the surrounding air should not exceed 50%. Low temperature allows a large relative temperature (e.g. +20 ° C is 90%). Consideration should be given to the effect of condensation caused by temperature changes
- Inclination with vertical plane is not more than 5°, and the whole group of cabinets is relatively flat, in line with (GBJ232-2) standard
- Requested in no violent vibration and impact, electrical components will not be corroded, no conductive dust place
