FAQ (For African Distributors & EPC Companies)

Q1: What is the lead time for this 200kVA dry-type transformer?
A: Standard production time is 25–30 days after drawing approval and deposit. Shipping to major African ports takes approximately 35–45 days by sea. Air freight is available for urgent orders.

Q2: Can this transformer be used outdoors?
A: The standard version is IP00 for indoor use. For outdoor installation, we recommend IP23 or IP54 enclosures with weather protection.

Q3: Do you provide test certificates and technical documentation?
A: Yes. We provide routine test reports, material certificates, wiring diagrams, and installation manuals. Third-party inspection is welcome at additional cost.

Q4: What are the payment terms?
A: Typically 50% T/T deposit, 50% balance before shipment. L/C at sight is acceptable for qualified partners. Longer payment terms may be considered for repeat customers.

Q5: Can you match local voltage standards in different African countries?
A: Yes. We can customize primary and secondary voltages to match grid requirements in Nigeria , Kenya, Ghana, South Africa, and other countries.

Q6: What is the difference between isolation transformer and auto-transformer?
A: An isolation transformer has separate primary and secondary windings, providing electrical isolation and better protection for sensitive equipment. An auto-transformer shares windings and is more compact but offers no isolation. Our 200kVA dry-type is a true isolation transformer.
