Frequently Asked Questions
Q1: Can this switchgear be used at high altitudes?
Yes. While the standard design is rated for altitudes ≤1000m, it can be customized for higher altitudes. Currently, there are 6 sets successfully operating at an altitude of 5200m.
Q2: What is the operating temperature range for this equipment?
The switchgear is designed to operate reliably in ambient temperatures ranging from -35℃ to 45℃, with a maximum daily average temperature difference of ≤25℃.
Q3: Which international and national standards does this product comply with?
The equipment complies with GB3906-2006 (for 3.6 kV to 40.5 kV AC metal-enclosed switchgear), IEC 60298-1990 (for nominal voltages above 1kV and below 52kV), and GB/T11022-2011 (common technical requirements for high-voltage switchgear).
Q4: What is the IP protection level of the switchgear?
This switchgear has a protection rating of IP3X, which ensures standard protection against solid foreign objects.
Q5: How do I choose the right height dimension for my cables?
The height (H) of the switchgear depends on your cable type: heights of 1400mm and 1600mm are suitable for single-core electric cables, while a height of 1800mm is designed for three-core electric cables.
