FAQs
FAQs
1. What voltage range do your medium and high voltage switchgear cabinets cover?
Our medium and high voltage switchgear cabinets are designed for typical MV/HV levels, such as 10 kV, 12 kV, 24 kV and up to around 35–40.5 kV, depending on project needs.
When you send an inquiry, please specify the exact system voltage and frequency so we can select the right switchgear configuration for your grid.
2. How is safety ensured in medium and high voltage switchgear cabinets?
Safety is ensured through properly rated circuit breakers, robust insulation coordination, clear compartment separation and reliable earthing systems.
Many modern MV/HV switchgear designs also support internal arc classification, giving operators improved protection if a fault occurs inside the cabinet.
3. Which standards and type tests do your switchgear cabinets comply with?
Medium voltage and high voltage switchgear is typically designed and tested according to high‑voltage switchgear standards that define ratings, design rules, type tests and routine tests.
These standards cover dielectric tests, short‑circuit withstand tests, temperature‑rise tests, mechanical function checks and, where applicable, internal arc fault verification.
4. What are the main applications of medium and high voltage switchgear cabinets?
Medium and high voltage switchgear cabinets are widely used in utility substations, industrial plants, mining operations, infrastructure projects and large commercial complexes.
They are installed at key points in the network to control, protect and isolate feeders and transformers, ensuring reliable power supply to downstream systems.
5. Can your MV/HV switchgear cabinets be customized for my project?
Yes, MV/HV switchgear cabinets can be tailored according to your single‑line diagram, fault level, feeder quantity and preferred device brands.
Busbar schemes, compartment layouts, enclosure dimensions and protection and control equipment can be adjusted to match your technical specifications and site conditions.
6. What information should I provide to get a detailed proposal?
To receive a detailed proposal, please share your system voltage and short‑circuit level, single‑line diagram, load list and any required standards or certifications.
Additional data such as installation environment, altitude and ambient temperature helps engineers design a medium or high voltage switchgear solution that fits your real operating conditions.
