How do you package transformers to ensure safe transport?

We use sturdy wooden crates with internal securing and moisture-proofing for LCL shipments, or secure fastening inside containers for FCL shipments. All cases are fumigated for customs clearance.

What is the warranty period?

We offer a 12-month warranty from the date of manufacture. Extended warranties are available for major components upon request.

How do you provide technical support if the product malfunctions?

We provide remote guidance via phone, email, or video, and can dispatch engineers for on-site service if required. We also guarantee long-term supply of spare parts.

We mainly produce oil-immersed transformers suitable for outdoor and large industrial projects, and dry-type transformers ideal for indoor commercial buildings and data centers.

Q:What are the primary materials for transformers? Are windings copper or aluminum?

We offer both copper and aluminum windings. Copper offers higher conductivity and efficiency, while aluminum is a lower-cost, lighter-weight alternative. Selection depends on budget and efficiency requirements.

Q:What is the minimum order quantity?

For standard products, the minimum order quantity is 1 unit. For customized products, the MOQ is determined through negotiation based on specific specifications.

Q:What payment methods do you accept?

We accept T/T (Telegraphic Transfer), typically with a 50% advance payment and 50% balance before shipment. Other methods like L/C, D/P, and PayPal are also available.

Q:What is the delivery lead time?

Lead times depend on the type and quantity. Standard small transformers take 15-30 days, while large or custom transformers take 45-90 days or longer.
