1. For a 2,500 kVA integrated power system using a silicon-steel–core, Class‑1 efficiency transformer, can the overall footprint still be optimized?
Answer: In general, using an amorphous‑alloy transformer can reduce volume by about 20%–30 %, whereas a silicon‑steel solution yields around 10%–15 % reduction.
2. In a data‑center computer hall with standard column spacing of 10 m, if our module is 14.1 m long and cannot avoid structural columns, can we install an empty cabinet section?
Answer: Two solutions are possible:
If the column is set back and only intrudes slightly into our equipment plane, install an empty “transition” cabinet to bridge the offset.
If the intrusion is more severe, use a compact bus‑duct connection in place of a transition cabinet.
3. Your integrated power system is designed with full copper busbars. If the customer requests cable connections instead, will the price increase?
Answer: Full copper busbars are our standard. Substituting part of the busbar with cables requires a bespoke cost estimate based on cable type and routing length. Typically, the added cost is in the range of 1 %–3 % of the total system price.
4. What are your advantages compared with other suppliers’ integrated power systems? Is your cost‑performance ratio high?
Answer:
UPS and other key components can be flexibly selected per customer requirements, making overall configuration and cost highly adaptable.
Core components—transformers and our cloud‑platform intelligent monitoring system—are in‑house manufactured.
Our three major production bases can deliver complete systems, with a monthly capacity of 2,550 units, ensuring reliable lead times.
We offer financing‑lease plans: as little as 10 % down payment (e.g., RMB 1 million on an RMB 10 million purchase), with financing costs 1 %–2 % lower than bank loans.
Product designs fully meet the standardization requirements of the three major carriers and leading network operators; we do not skimp on critical parts (e.g., both input and output cabinets include switchgear), yielding high product compatibility.
5. Your standard integrated power module is 14.1 m long, exceeding the design institute drawings. Can you produce a custom‑sized version?
Answer: 14.1 m is our standard. Once we receive the institute’s final drawings, we will coordinate with them to customize and reduce the footprint as needed.
6. Which manufacturers do you partner with? Are your UPS modules proprietary or sourced? On which projects have you collaborated? How much price difference is there compared to direct‑brand procurement? What is the warranty period? What are your emergency procedures in case of a single‑point failure causing a system blackout?
Answer:
UPS modules can be chosen from Schneider, Huawei, Eaton, Aitel, and others per customer preference. We handle all after‑sales support (24 × 7 response), with spare‑parts warehouses in all major cities.
Through our framework agreements, we typically procure UPS units at 8 %–12 % below what customers pay for standalone purchases. Customers may also specify “owner‑supplied” UPS, but owner‑supplied parts are excluded from our integrated‑module warranty and must be covered by the UPS supplier’s warranty.
We offer a three‑year full‑system warranty; extended warranty on critical components (e.g., UPS modules) is available depending on brand choice.
To ensure zero downtime, we support dual redundant power feeds, N+X hot‑standby UPS modules, and hot‑swap module replacement within 15 minutes.
7. What are the advantages of your UPS selection?
Answer: We support 100 % compatibility with all mainstream brands. Our modular design allows online capacity expansion; a failure of a single module does not interrupt operations, and MTTR (mean time to repair) is under 15 minutes.
8. What are the height and cabinet‑adaptation options for your UPS?
Answer: The standard UPS cabinet height is 2,000 mm; taller/custom cabinets are available upon request.
9. The upfront price seems high—can you save on operating costs? How much can be saved, and how much space reduction is achievable?
Answer:
Purchase price is on par with—or slightly below—traditional schemes, thanks to prefabricated copper busbars that cut cable costs by over RMB 300,000.
Operating‑cost savings include:
30 %+ footprint reduction. In a 12 MW data center, you can install ~170 additional racks vs. conventional PDUs, boosting revenue.
Simplified maintenance: trained staff can perform daily checks in under 10 minutes, cutting labor costs.
If you opt for our amorphous‑alloy transformer, you save about 11,000 kWh per module per year.
Using our financing‑lease plan, your financing cost is 1 %–2 % below prevailing bank rates."
10. Can your integrated power system be configured as a DC solution?
Answer: We support 48 V/240 V DC schemes; please specify at project outset. Custom design adds 10–15 days to the schedule.
11. Are all accessories in the integrated power system produced by your company?
Answer: Cabinets, busbars, transformers, and the cloud‑platform monitoring system are in‑house. Circuit breakers and UPS units are procured per customer specifications.
12. Is the warranty separated by transformer module, UPS module, etc., or is it a single system warranty? During warranty, do you replace or repair faulty products? After the warranty, is paid maintenance available?
Answer:
We offer a three‑year full‑system warranty (including transformers, UPS, and core parts). Faulty components are replaced or repaired at no charge during the warranty.
Post‑warranty, paid maintenance is available; contracts of three years or longer receive a 20 % discount.
13. What is the service life? After a major component fails, can you offer trade‑in or replacement options?
Answer:
Wear items are the UPS and SVG modules; their lifespans depend on the OEM quality.
Switchgear and circuit breakers have service lives exceeding 20 years (considering both mechanical and electrical operations).
14. Can you supply cabinets for diesel‑generator systems?
Answer: Generally not. We can broker them, but at higher cost. Diesel gensets are statutory “special equipment” in China and require specific licensing for in‑house production.
15. What is the production lead time for an integrated power system?
Answer: Lead time depends on component brands. Imported kits take longer and are not recommended; domestic sourcing is faster, typically at least 30 days, subject to supply‑chain factors.
16. How are the power‑module cabinets interconnected? How many busbar groups are required? Do they disassemble for installation?
Answer: Cabinets use plug‑in busbar connectors—four busbar assemblies per cabinet pair. We ship modules in sections for on‑site assembly.
17. Will the contract price for integrated power modules change if the detailed design drawings evolve? What is the typical scope of such variations?
Answer: Quoted prices are based on preliminary designs. Any cost changes due to deepened design, such as increased UPS capacity or altered cabinet count, will be adjusted per the revised configuration.
18. Can UPS units be replaced without shutting down power?
Answer: Yes—hot‑swap technology lets you replace UPS modules online; the system switches automatically to redundant modules, ensuring zero interruption.
19. How do you ensure dust protection and cleanliness? How stable is the equipment?
Answer:
Cabinet IP rating is IP20; lightning protection is Class B; environment is class A (temperature and humidity controlled indoors). Full specifications are in the user manual.
We record process quality data on‑chain for traceability and perform five levels of quality validation (including 48 h full‑load testing) before shipment.
20. Are you an ABB‑authorized cabinet assembler? What is your annual volume with ABB, and what discount can you obtain?
Answer: ABB is our strategic partner, with annual purchases over RMB 50 million. ABB circuit breakers are offered on a tiered‑discount basis, with custom pricing by project scale.
21. Do you provide “controlled spec” parameters for bids? If all specs are standard, how can I promote your product while protecting my margin?
Answer: We supply exclusive bid‑control parameters, e.g., Tier IV certification requirements, busbar current‑carrying capacities, and prefabrication rates.
22. I’ve heard you did OEM work for Kehua—can you share a redacted OEM contract for our sales team?
Answer: Due to confidentiality, we can provide redacted excerpts only after legal review.
23. Aside from the transformer, which you produce in‑house, which accessories do you manufacture versus purchase? From which suppliers?
Answer: Transformers, LV equipment, and the cloud platform are our own. UPS modules are sourced from reputable domestic and international OEMs with proven track records.
24. Do you offer customization? What is the approximate price and efficiency?
Answer: We support customization of dimensions, voltage, and brand. Prices vary ±5%–20 % based on requirements. Our 2,500 kVA standard scheme delivers ≥96 % efficiency at full load.
25. Do you have mature customer case studies? Can we visit a reference site?
Answer: Our products have passed national type‑test certifications, including short‑circuit, thermal‑rise, and multi‑mode efficiency tests. You are welcome to tour our production and QA facilities. We can also provide a bespoke proposal per your specs.
26. What performance evidence do you provide if you lack integrated‑power project references?
Answer: We can share third‑party test reports, independent modular sub‑system case studies (e.g., amorphous transformers and switchgear in service for 3 years), and deploy a free test unit onsite for performance validation.
27. How does the new design compare in cost to the old?
Answer: For a 2,500 kVA system, the new design’s procurement cost is 8 %–10 % higher, but when factoring in cable savings, the total cost is roughly equal or slightly lower. In a 12 MW data center, annual power savings approach RMB 2 million.
28. What is the approximate cost of an integrated power module?
Answer: A 2.5 MVA module (excluding HV cabinet) is roughly RMB 2.6 million; final pricing depends on selected components.
29. Which brands are your products comparable to?
Answer: Our systems are on par with Huawei, Delta, Vertiv, Kehua, and Eaton. We also excel in turnkey system R&D and manufacturing—PCS all‑in‑one units, MV/LV switchgear, and smart‑cloud platforms are shipped domestically and internationally. Unlike most Tier 1 vendors, we enable full customer involvement in product customization.
30. If you have no track record and no price advantage, why choose you?
Answer: We lower the total life‑cycle cost by:
Flexible configuration and deep customer involvement in design (unlike closed approaches by other Tier 1 vendors), enabling lower overall system price while meeting specs.
Our “Rong‑Yi‑Gou” financing lease, with as little as 10 % down to energize the system, reduces both capex and project‑funding risks, and guarantees delivery & construction timelines.
31. Do you have IEC or international certifications?
Answer: There is currently no dedicated IEC certification for “integrated power modules” per se—only for individual components such as transformers and switchgear.
32. For split transport, are busbars shipped intact or segmented?
Answer: They are shipped in segments for on‑site assembly.
33. For after‑sales, if the customer demands a 30‑minute response and on‑site arrival within 2 hours, can you meet that?
Answer: We provide 24 × 7 support via hotline and online; service‑level packages define on‑site response times (e.g., 4 h or 2 h), ensuring rapid fault recovery.
34. Is your UPS proprietary or third‑party? How do you handle third‑party UPS support and spare parts responsiveness?
Answer: UPS modules are from Schneider, Huawei, Eaton, Aitel, etc., per customer choice. We coordinate all after‑sales (24 × 7) with spare parts depots in major cities.
35. What are typical delivery times by transport mode?
Answer: After factory acceptance, domestic road transport within ~1,000 km typically takes ≤3 days.
36. How do you handle sudden quality issues?
