FAQ
Frequently Asked Questions
Quick answers about our electrical solutions
What certifications do your switchgear products hold?
All HV/LV switchgear, RMU, and prefabricated substations are ISO 9001, CCC, CE, and IEC 62271 certified. We also hold 20+ national patents.
Can you customize voltage ratings and configurations?
Yes, full OEM/ODM customization: rated voltage (11kV–40.5kV), current capacity (up to 6300A), IP rating (IP40–IP65), and intelligent monitoring. Engineering drawings welcome.
What is the lead time for a 33kV ring main unit?
Standard RMU lead time is 25–35 days; expedited service available for urgent projects.
Do you export to Europe, North America, and Middle East?
Yes, we export to over 40 countries including Germany, USA, UAE, Saudi Arabia, and Southeast Asia. All products meet IEC and other international standards.
What warranty and after-sales support do you provide?
12–24 month warranty, remote troubleshooting, on-site commissioning assistance, and global spare parts supply.
How to choose between air-insulated and gas-insulated RMU?
Air-insulated RMU is cost-effective and suitable for indoor spaces; gas-insulated (SF6) is compact and maintenance-free, ideal for harsh environments or space-limited substations.
Technical Comparison: Air-insulated vs. Gas-insulated RMU
| Feature | Air-insulated RMU | Gas-insulated RMU (SF6) |
|---|---|---|
| Size | Larger | Compact (up to 70% smaller) |
| Maintenance | Regular cleaning required | Virtually maintenance-free |
| Environment | No greenhouse gas | SF6 has high GWP (alternative gases available) |
| Typical Application | Indoor substations, industrial plants | Underground, harsh environments, space-limited |

How does the term 'other' function in legal documents and contracts?
- The term 'other' serves a critical function in legal documents and contracts, primarily as a catch-all or residual category. Its purpose is to encompass unforeseen or unspecified items, rights, obligations, or circumstances that do not neatly fit into explicitly defined terms. This drafting tool provides flexibility and helps ensure comprehensive coverage, preventing loopholes that might arise from an exhaustive list. However, its broad and potentially vague nature can also lead to ambiguity and disputes over interpretation. Courts often scrutinize the context of the entire agreement to determine the scope of 'other' provisions. Therefore, while useful for completeness, the term requires careful consideration to balance clarity with the need for contractual flexibility.
