Indoor Vacuum Circuit Breaker HFEV Series : Secure Handling, Safe Storage
1. Receiving Inspection:
Upon the arrival of indoor medium voltage vacuum circuit breaker, it’s crucial to conduct a thorough receiving inspection. Verify that the model specifications and quantities match your order. When inspecting the goods, handle with care to prevent any damage to the breaker or its packaging. We recommend retaining the original wooden case for protection until installation. Even if installation is imminent, ensure breaker HFEV is stored in its packaging, considering waterproof and moisture-proof measures. Should you encounter any issues, reach out within a 5-day window post-receipt to address any discrepancies or damages.
2. Storage and Transportation:
To ensure the service life and performance of medium voltage vacuum circuit breaker, proper storage and transportation guidelines must be followed. indoor vacuum breaker should be stored in a dry, dust-free environment, away from corrosive and explosive substances, and the storage temperature range is -40℃~ +70℃.Set the breaker horizontally on a fixed base to avoid direct contact with the ground. During both storage and transportation, ensure the breaker is turned OFF and the spring mechanism is discharged to prevent accidental activation. Always exercise caution to protect both the breaker and personnel, as improper handling, such as tipping, striking, or dropping, can result in damage. Protecting your equipment during this phase is critical to uninterrupted service and reliability.
