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

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.

Design Review Process

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.

01

Requirement Analysis

Understand customer needs and specs.

02

Basic Design

Confirm core parameters such as materials and cooling method.

03

Detailed Design

Review winding and core details submitted by the manufacturer.

04

Magnetic Circuit Design

Confirm flux density is within design tolerance.

05

Winding Design

Review winding structure and parameters.

06

Cooling System Design

Confirm cooling method matches site conditions.

07

Thermal Stability Analysis

Review temperature rise under rated and overload conditions.

08

Electromagnetic Compatibility

Confirm interference is within acceptable limits.

09

Performance Simulation and Testing

Validate design accuracy before manufacturing begins.

Manufacturer Matching

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.

01

Confirm product type, capacity and technical spec

02

Screen manufacturers by relevant capability and certification

03

Cross-check lead time and capacity against your project schedule

04

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.

Manufacturing Coordination

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.

Quality Control

How We Manage Quality

Available upon project requirement — scope depends on product type, manufacturing partner and contract terms.

01

Technical Specification Review

02

Drawing Approval

03

Key Material Confirmation

04

Production Inspection

05

Factory Acceptance Test (FAT)

06

Third-Party Inspection

07

Packing & Shipment Inspection

08

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

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

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

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.
