13
What is the biggest difference between ASNA RMU/Switchgear and other similar technologies?
Compared with other similar technologies, the most significant difference of the circuit breaker based ASNA RMU/Switchgear lies in its atmospheric pressure sealed natural air insulated technology. It has no internal pressure and zero gas leakage risk. It is suited for smart distribution grid requirements and delivers higher reliability.
14
Is further expansion possible after the switchgear has been commissioned?
ASNA RMU/Switchgear supports side by side extension on both left and right sides. Custom built extension cubicles are not necessary. Upon project commissioning, dedicated expansion kits are available for rapid on site bay extension, minimizing operational downtime.
15
Are video tutorials and illustrated manuals available for installation and commissioning?
Yes. Relevant videos and manuals are available in the "Downloads" section of our website, and can also be accessed via our YouTube channel.
16
What are the typical transit times?
Below are reference transit times for shipments to Europe (excluding production lead time and customs clearance): air freight: 7 10 days sea freight: 30 38 days rail freight (China Europe Railway Express): 18 22 days
17
How are products packed for dispatch?
As standard, each ASNA switchgear unit gets individual packaging. Consolidated packaging is available for specific projects. This optimizes shipping and reduces on site cubicle coupling work.
18
What shipping options are available for shipment?
Our proximity to Guangzhou gives us excellent logistics accessibility. We can arrange sea freight, air freight, China Europe Railway Express and international courier services as required.
19
How many switchgear units fit into one container?
For reference: 28 units of 24 kV /630 A ASNA RMU/Switchgear fit in a 40 ft container, while 24 units of 12 kV /630 A ASNA RMU/Switchgear can be loaded into a 20 ft container. Loading quantities for other models are calculated according to switchgear outer dimensions.
20
How is the product packaged?
We use moisture proof bags and fumigated wooden crates for packaging. Desiccants are placed inside the moisture proof bags to avoid drastic ambient humidity fluctuations, regardless of transport mode. This protects the products against moisture ingress during transportation and storage.
21
What is the production cycle for switchgear?
The in house production cycle is subject to unit quantity and switchgear model. Typically, it takes around 30 days.
22
Is customized production available?
Our ASNA (atmospheric sealed natural air insulated) RMU / switchgear is a standard type unit. Customization is available for the secondary circuit per customer needs, including closing tripping coils in various voltage ratings (230 V / 48 V / 24 V).
23
How to ensure the workmanship and quality of ASNA RMU/Switchgear during production?
Our production system complies with European manufacturing specifications. Strict process controls are implemented across all stages: raw material incoming & warehousing, in production inspection, and final factory release. Backed by our production team’s extensive switchgear manufacturing experience, we secure consistent product quality while optimizing production efficiency.
