Product Features

Higher Safety

1) Modular overall design, each module can be safely replaced in a standardized way; 

2) Explosion-proof and flame-retardant isolation is designed between each switch.

Higher Reliability

1) Upward and downward information adopts digital transmission, which is more reliable than analog transmission; 

2) The integrated monitoring module will not affect the operation of each power functional module; 

3) Reliable solutions are configured for faults such as DC/DC feeder faults.

Higher Cost Efficiency

1) Fully modular and fully digital design saves a large amount of secondary cables;

2) The intelligent switch module can accommodate more switches than conventional designs, and the number of cabinets can be reduced under certain conditions;

3) Standardized design, production and maintenance optimize the full life-cycle cost of products; 

4) Assembled design shortens product delivery cycle.

Better Usability

2) Integrated monitoring design makes patrol inspection, accident handling and management analysis more convenient.
