Product Detail

SF6 is a high-voltage switchgear in which all high-voltage live parts are sealed in the gas box, which can completely prevent operators and maintenance personnel from touching high-voltage parts, ensuring the personal safety of maintenance personnel. At the same time, it can prevent harmful substances such as moisture and dust in the external environment from affecting the insulation level and operating life of live parts, ensuring reliable operation of the equipment throughout its life cycle. The protection level of the gas box is IP42, and adding a protective shell can meet the requirements of outdoor use. In addition, the cabinet is compact in design and small in size, which is convenient for handling and transportation and can save space.

 

     Product Features     

1. Equipped with a ±0.1mm high-precision industrial robot, it achieves millimeter-level control of switchgear bending and assembly, achieving a component standardization rate of ≥99% and a dimensional qualification rate exceeding 99.5%.

2. All its live parts and switches are enclosed in a stainless steel housing and are not affected by external environmental conditions, thus ensuring high reliability and safety and achieving maintenance-free operation.

2. German imported spraying system

Adopting electrostatic spray guns and water-based environmentally friendly paint, the coating uniformity error is ≤5μm, VOC emissions are reduced by 80%, and "zero-defect appearance" and green manufacturing are achieved simultaneously. The spraying defect rate is controlled within 0.3%.

3. Fully automated production

Relying on Schneider's benchmark intelligent production line, a fully automated production model is created, manual intervention is reduced by 70%, the production cycle of a single cabinet is compressed to 30 minutes, and the production capacity is increased by 30%.

 

     Full Automatic Production Line     

Relying on Schneider's benchmark intelligent production line, we have created a fully automated production model of "the cabinet moves but the people do not move". Manual intervention is reduced by 70%, the production cycle of a single cabinet is compressed to 30 minutes, the production capacity is increased by 30%, and the process is fully benchmarked against IEC/GB international standards. From precision manufacturing to environmental protection upgrades, we use the dual-wheel drive of "technology + efficiency" to ensure that each switch cabinet has both industrial aesthetics and ultra-long life to meet the needs of global high-end power projects.
