Frequently Asked Questions
Q1: What are the normal operating temperature limits for this equipment?
The equipment is designed to operate in environmental temperatures ranging from a minimum of -25℃ to a maximum of +40℃, with a 24-hour average temperature not exceeding 35℃.
Q2: Can the system be used at altitudes higher than 1500 meters?
The standard type is rated for altitudes up to 1500 meters under standard gas pressure. For installations exceeding 1500 meters, special instructions and custom consultations are required.
Q3: What is the protection level and annual gas leakage rate?
The gas tank features an IP67 protection rating, while the shell holds an IP3X rating. The annual gas leakage rate is exceptionally low at ≤0.05%.
Q4: How does the mechanical service life differ between modules?
The mechanical service life varies by module: the V Module (Vacuum Breaker) has a life of 10,000 operations, the C Module (Load Switch) and F Module (Composite Apparatus) support 5,000 operations, and the Isolation/Earthing Switch supports 3,000 operations.
Q5: What are the dimensions for different loop configurations?
While the height is 1336 mm and depth is 850 mm (935 mm total) across all configurations, the width (W) scales as follows: 1-way: 371mm, 2-way: 696mm, 3-way: 1021mm, 4-way: 1346mm, and 5-way: 1671mm.
Q6: What arc extinguishing technology is used in the switchgear?
This switchgear utilizes the reliable Vacuum Extinction method for high-efficiency and safe arc extinguishing during operations.
