Practical Answers for Transformer Selection and Projects
What information is required for a transformer quotation?
Please provide the transformer type, rated capacity, primary and secondary voltage, frequency, phase, vector group, impedance, cooling method, applicable standard, quantity and delivery destination. Load details and drawings help us prepare a more accurate proposal.
How do I choose between oil-immersed and dry-type transformers?
Oil-immersed transformers are widely used for outdoor utility and industrial systems, while dry-type transformers are often selected for indoor, fire-sensitive or low-maintenance locations. The final choice depends on capacity, environment, safety requirements and lifecycle cost.
Can transformers be customized for project-specific requirements?
Yes. Voltage, capacity, frequency, impedance, vector group, enclosure, cooling method, accessories, color, marking and packaging can be configured around the approved technical specification.
Which standards and factory tests can be provided?
Products can be designed around the confirmed project standard. Routine tests and quality documentation are prepared before shipment. IEC, GB, CE and ISO-related claims will only be displayed where valid documents and product scope have been verified.
How are production time, packing and delivery confirmed?
Lead time is confirmed after technical approval, quantity and configuration review. Packing and transport are planned around transformer size, destination and handling conditions, with export coordination through delivery.
What is the typical lead time for a custom transformer?
Lead time depends on transformer type, rating, voltage class, quantity, materials and testing requirements. After the technical specification is confirmed, we provide a production schedule with drawing approval, manufacturing, testing, packing and estimated dispatch dates.
Can you provide technical drawings and documents before production?
Yes. For confirmed projects, we can provide outline drawings, nameplate data, technical datasheets and other agreed documents for customer review. Production begins after the required technical details and drawings are approved.
Do you support third-party inspection and witness testing?
Yes. Customer representatives or appointed third-party inspectors may witness agreed factory tests subject to advance scheduling. We can coordinate the inspection plan, test records and supporting documentation before shipment.
How do you protect transformers for international shipping?
Packing is selected according to transformer type, dimensions, transport route and destination. We use moisture protection, reinforced supports and export-suitable packaging as required, and provide loading photos and shipping documents for the order.
What information helps you recommend the correct transformer capacity?
Please share the connected load, maximum demand, load type, starting current, duty cycle, expected future expansion, ambient conditions and installation method. Our engineering team can review these details and recommend a practical rating and configuration.
