YS Engineering Solution provides comprehensive VCB (Vacuum Circuit Breaker) Maintenance and Service solutions, which are critical for ensuring the reliable operation and protection of medium-voltage power Distribution networks. The service is preventative and focused on detailed internal and external component checks. Key activities include thorough cleaning, lubrication of the mechanical operating mechanisms, and verification of crucial parameters such as contact resistance and the integrity of the vacuum interrupters. Most importantly, professional technicians conduct rigorous Secondary Injection Testing on the associated protection relays to guarantee accurate and swift tripping under fault conditions. This meticulous maintenance minimizes the risk of catastrophic failures, prevents insulation breakdown, and significantly extends the service life of the expensive VCB equipment.
