Ground terminal is the best choice for rail transit components

No matter which field of transportation equipment has common characteristics, the extreme environment affects the application of components. The basic requirements of components used in transportation equipment are reliability and long-term maintenance-free.
Why is the ground terminal a must for rail transit?
1. The subway station project is a century-old project, and the grounding grid of each station is set below the main structure of the station. Once the implementation is completed, it basically does not have the conditions for replacement.
2. According to national regulations, for the grounding materials used in subway stations, on the premise of meeting other grounding requirements, the impact of corrosion should also be considered, based on specific geological survey data.
The soil under the subway station is generally corrosive. At the same time, considering that the subway itself will also increase the corrosion of the grounding material to a certain extent, compared with other grounding materials (such as steel, etc.), the copper material has Good corrosion resistance, can meet the actual life needs of the subway 100-year project.
3. In view of the problem that it is not easy to protect the grounding terminal of the subway station using copper materials, the Suppo terminal has considered the protection measures in the design of the subsequent grounding construction drawing, and proposed that after the construction is completed, the grounding lead should Please pay attention to proper storage, and it can be wrapped with oil cloth and sealed with cement to avoid loss and breakage.

KNLE1-63 Residual Current Circuit Breaker With Over Load Protection

KNLE1-63 TWO FUNCTION : MCB AND RCCB FUNCTIONS

leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
