From initial consultation to final commissioning, we work closely with you to deliver transformers that perfectly match your specifications, installation constraints, and operational environment.
Everything you need to know about our custom transformer services
We accept custom orders starting from 1 unit. Whether you need a single prototype or bulk production, we can accommodate your requirements. For larger quantities (10+ units), we offer volume discounts and can optimize tooling costs.
The typical timeline is: Design & Engineering (2-3 weeks), Prototype Development (3-4 weeks), Testing & Validation (1-2 weeks), and Mass Production (4-6 weeks). Total lead time is usually 6-8 weeks for standard custom projects. Complex projects may require additional time.
Yes, we can reverse-engineer existing designs and provide improvements. Our team can analyze your current transformers, identify weaknesses or inefficiencies, and develop enhanced versions with better performance, reliability, or cost-effectiveness.
We provide comprehensive documentation including: detailed technical drawings, electrical schematics, test reports (FAT), material certificates, quality inspection records, operation & maintenance manuals, and compliance certificates (CE, ISO, etc.).
Yes, we strongly recommend prototyping for new designs. We can manufacture prototype units for testing and validation before committing to full production. This allows you to verify performance, make adjustments, and ensure the design meets all requirements.
We conduct testing per international standards including IEC 60076 series, IEEE C57 series, and GB/T standards. Testing includes routine tests, type tests, and special tests as required. We can also perform testing per customer-specific standards or requirements.
For OEM projects where you provide the design, you retain full IP ownership. For ODM projects where we design the solution, IP ownership is negotiable and typically defined in the contract. We can offer exclusive designs or shared IP arrangements based on your needs.
We provide a standard 2-year warranty covering manufacturing defects and material issues. Extended warranty options (up to 5 years) are available. The warranty includes free replacement of defective parts, technical support, and on-site service if needed.
Yes, we have extensive experience in international logistics. We can handle all export documentation, customs clearance, and shipping arrangements. We work with reliable freight forwarders and can deliver to any location worldwide.
Standard terms are 30% deposit upon order confirmation, 60% before shipment, and 10% after installation/commissioning. For established customers or large projects, we can negotiate flexible payment terms including L/C, installment payments, or other arrangements.
