Frequently Asked Questions
Q1: What's the difference in the circuit breaker for air-insulated vs gas-insulated?
A: Air-insulated switchgear circuit breaker is typically removable or withdrawable.The circuit breaker is based on vacuum circuit technology.In the gas-insulated,it is fixed mounted.The function of withdraw is provided by a separate disconnecting switch.Typically,a three-position switch with connected,disconnected,and ready-to-earth position.
Q2: What are the key features of Huachi Electric's medium voltage switchgear products?
A: Huachi Electric's primary medium voltage switchgear products are designed to connect and protect the evolving grid.They feature robust construction,advanced safety mechanisms,high reliability,and ease of maintenance.They are designed to handle high electrical loads and provide efficient power distribution with minimal losses.
Q3: What is the typical service life of Medium Voltage Air Insulated Switchgear?
A: With proper maintenance,air insulated switchgear is engineered for service life exceeding 30 years .Vacuum circuit breakers offer tens of thousands of mechanical operations,and robust construction ensures long-term durability.Maintenance intervals typically exceed 10 years,reducing lifecycle costs.
