main features of the product:

1. excellent breaking performance. the single-fracture interrupter adopts variable opening range and double nozzles. the circuit breaker has the ability to break both short and long arcs. the nozzle under the best scheme strengthens the de-ionization effect of the arc gap after contact separation and improves the recovery strength of the insulating medium between contacts after short-circuit current crosses zero.

2. strong current capacity. the current capacity of the whole gis reaches 4,000 a. the silver plating on the electrical contact surface has been conducted automatically with international leading technology, instead of manual silver plating, through the introduction of toshiba's automatic silver plating production line in japan. the plating has the uniform thickness, high hardness and strong adhesion, making the current capacity of the product stronger.

3. the product adopts an aluminum shell, which has the advantages of light weight, low temperature rise and corrosion resistance. the shell opening adopts one-step stretch forming technology to avoid the irregularity of the shell interface. the outer surface of the aluminum shell is coated with thu iron red epoxy primer and b05 acrylic polyurethane enamel, which has excellent corrosion resistance.

4. excellent insulation performance. the production of basin insulators and post insulators adopts the automatic pouring in the production line of hubers company (germany), and the whole process from mixing and heating of resin and filler to pouring and forming is finished completely under sealed conditions.

5. excellent sealing performance. on the basis of finish machining, the shell flange and sealing surface have adopted advanced "rolling technology" to make the sealing surface finish up to 0.8, thus ensuring the sealing performance of the sealing surface; the double sealing is adopted for outdoor seal to achieve better sealing performance.

6. the circuit breaker can adopt the hydraulic mechanism to realize three-phase mechanical linkage. in order to improve the reliability of the power system, the three-phase mechanical linkage of the circuit breaker can be realized according to the user's requirements to ensure the safe and reliable operation of the power system.

7. it meets the requirements of iec 62271-1, iec 62271-100, iec 62771-102, iec 62271-203 and other relevant standards;
