Custom Transformer Core Manufacturing
Transformer Core Procurement Request
Submit your drawings and technical requirements. We will check material, core structure, stacking method, packing, and delivery terms before quotation.
Submit Transformer Core RFQTechnical scope before quotation
This page is for transformer manufacturers purchasing custom transformer cores, MSL cores, cut laminations, or CRGO / GOES slitted coils according to drawings and technical requirements. Clear scope information allows Chenfan Electric to review manufacturability, material, packing, and delivery conditions before issuing a quotation.
Products separated by procurement scope
Fully Assembled Laminated Transformer Cores
Core assemblies manufactured according to customer drawings, material requirements, and packing conditions.
Multi-Step Lap Transformer Cores
MSL joint structure used to improve magnetic path continuity and reduce joint-related manufacturing variation.
Cut Laminations
Cut-to-size CRGO / GOES laminations supplied according to drawing dimensions and stacking requirements.
CRGO / GOES Slitted Coils
Slitted coils supplied for transformer core production according to required width and material specification.
Export Packing for Sea Shipment
Packing designed to reduce movement, moisture risk, and handling damage during international transport.
Core assembly according to customer drawings
Manufacturing scope is reviewed against the core drawing, material requirement, core configuration, stacking method, clamping condition, and packing requirement. Assembled transformer cores are not the same procurement object as CRGO raw material or loose cut laminations.
Joint geometry requires controlled cutting and stacking
Multi-Step Lap construction depends on consistent step sequence, lamination dimensions, joint alignment, and stacking condition. The final core scope must be confirmed from the drawing and required assembly condition.
Slitted coils for transformer core production
Required width, grade, thickness, coil condition, quantity, and packing method should be specified. Slitted coil pricing and finished transformer core pricing must be evaluated as different supply scopes.
Send enough information for a usable technical review
- Transformer capacity: kVA / MVA
- Core type: single-phase / three-phase / five-limb
- Core drawing: PDF / DWG / DXF
- CRGO / GOES grade and thickness: 0.23 mm / 0.27 mm / other
- No-load loss target, if available
- Quantity or estimated total weight
- Delivery term: EXW / FOB / CIF
- Destination port
- Packing requirement
Process control across the manufacturing chain
- Burr height controlled below 0.02 mm
- Stacking factor above 97% for standard laminated transformer core production
- Multi-Step Lap joint structure for magnetic path continuity
- Dimensional inspection according to customer drawings
- Packing designed to reduce movement and moisture risk during sea shipment
Transformer core performance depends on the full manufacturing chain: material selection, cutting accuracy, burr control, stacking condition, joint design, clamping stress, and packing stability.
Protection for international handling and sea shipment
Packing scope should be confirmed with the core size, total weight, lifting method, moisture protection, transport route, and unloading conditions. Export packing reduces transport risk but does not replace correct handling at each logistics stage.
