40.5kV Sensor
2. Installation Method: Vertically or horizontally mounted within the cabinet and between conductive components.
3. Compatible Cabinets: Suitable for KYN61-40.5 type cabinets.
4. Product Advantages: Real-time monitoring, accuracy, non-contact monitoring, remote monitoring, and data analysis and prediction.
40.5kV sensor is suitable for three-phase AC systems power stations and substation distribution equipment with a rated voltage of 40.5kV and a frequency of 50~60Hz. It is used to allow conductive parts to pass through partitions, walls, or other grounded objects, providing insulation support and establishing a secure connection with external conductors (busbars).

Product Advantages
Offers continuous monitoring of insulators, identifying potential issues early. It tracks parameters like insulator temperature and leakage current, issuing alerts for any abnormal changes, enabling quick preventive action.
Delivers precise measurements of various parameters. Optical sensors detect surface cracks and damage, while electrical sensors measure leakage current to assess insulation performance. Multi-sensor fusion technology enhances accuracy and reliability.
Enables monitoring without touching the insulator, preventing damage. This is especially useful for high-voltage transmission lines, where monitoring can be done without interrupting power flow.
Integrates with communication technology to allow real-time monitoring from a control center. This improves efficiency, reduces labor, and saves time.
Processes collected data to evaluate and forecast insulator conditions. Historical data is used to predict the lifespan and failure probability, aiding in maintenance and replacement planning.

Product Applications
Widely used in power systems, including high voltage transmission lines and substations, 40.5kV sensor enhances system reliability and safety by continuously monitoring insulator status, reducing the risk of outages due to insulator failures.
