Engineering, Manufacturer Matching & Project Coordination
How Topi Power carries a project from first spec to long-term service — electrical engineering, manufacturer matching, production coordination, quality control, testing, delivery and after-sales support.
Electrical Engineering
Our technical team reviews every requirement against applicable standards before we ever approach a manufacturer, so the proposal you receive is grounded in a real technical assessment, not a generic price sheet.
Requirement & Standards Review
We confirm capacity, voltage class and applicable standards (IEC, IEEE/ANSI, CSA, GOST and destination-market requirements) against your project.
Specification Development
Customer requirements are translated into a clear technical specification manufacturers can quote against.
Design Review & Validation
Manufacturer-submitted designs, drawings and datasheets are checked against your original specification before approval.
Compliance Coordination
We track testing, certification and documentation requirements through to delivery, coordinating with the manufacturing partner.
What Our Technical Review Covers
Transformer design and manufacturing is carried out by our manufacturing partners. Our technical team reviews and approves each stage against your specification before production proceeds.
Requirement Analysis
Understand customer needs and specs.
Basic Design
Confirm core parameters such as materials and cooling method.
Detailed Design
Review winding and core details submitted by the manufacturer.
Magnetic Circuit Design
Confirm flux density is within design tolerance.
Winding Design
Review winding structure and parameters.
Cooling System Design
Confirm cooling method matches site conditions.
Thermal Stability Analysis
Review temperature rise under rated and overload conditions.
Electromagnetic Compatibility
Confirm interference is within acceptable limits.
Performance Simulation and Testing
Validate design accuracy before manufacturing begins.
Manufacturer Matching
We match your technical parameters, certification requirements, lead time and budget against manufacturers across our network of transformer, switchgear, solar PV and energy storage producers in China.
Confirm product type, capacity and technical spec
Screen manufacturers by relevant capability and certification
Cross-check lead time and capacity against your project schedule
Confirm pricing and commercial terms with the matched manufacturer
Manufacturer capability, history and certifications belong to that manufacturer — we present them as such, never as Topi Power's own. See About — Manufacturing Network for our Wujiang Transformer Co., Ltd reference.
How We Coordinate Production
Manufacturing is carried out by our partners. Our role is to keep production on track and quality consistent with what was approved.
Progress Tracking
We track core assembly, winding, insulation treatment and final assembly milestones against the agreed schedule.
Quality Checkpoints
Key stages — material confirmation, insulation testing, structural and electrical withstand tests — are checked before a unit is cleared to ship.
Documentation Handling
Test reports, certificates and drawings are compiled and reviewed as production completes, ready for delivery with the shipment.
How We Manage Quality
Available upon project requirement — scope depends on product type, manufacturing partner and contract terms.
Technical Specification Review
Drawing Approval
Key Material Confirmation
Production Inspection
Factory Acceptance Test (FAT)
Third-Party Inspection
Packing & Shipment Inspection
Technical Document Control
Products can be supplied and tested in accordance with applicable IEC, IEEE/ANSI, CSA, GOST and destination-market requirements, subject to product type and manufacturing partner.
Testing & Documentation
Routine tests, type tests, factory acceptance testing and independent third-party inspection can be coordinated with the manufacturing partner, available upon project requirement. Documentation — test reports, certificates, outline/GA drawings — is compiled per order and depends on the manufacturing partner and product type, confirmed at quotation stage.
International Delivery
Packing, export documentation and shipment coordination to your destination port are handled alongside the manufacturing partner. Exact lead time and shipping method are confirmed per order, based on the manufacturing partner's production schedule and your project's target delivery window.
Commissioning & After-Sales Service
Support available upon project requirement — exact scope depends on the manufacturing partner and contract terms.
We coordinate installation assistance, warranty support and technical troubleshooting with the manufacturing partner throughout your equipment's service life, and can help source replacement parts when needed.
