Transformer-Specific Electrical Laminated Wood | Bulk Procurement and Customization Services

Electrical laminated wood is a high-performance insulation and structural material that plays a crucial role in the design and manufacture of power transformers, reactors, and high-voltage switchgear. This material possesses excellent mechanical strength, electrical insulation properties, and environmental adaptability, making it a commonly used material for manufacturing key components such as supports, spacers, and clamping insulation. When making bulk purchases or special customizations, selecting a professional and reliable supplier with comprehensive technical support is essential for the smooth progress of the project.

Main Uses of Electrical Laminated Wood in Transformers

Electrical laminated wood is made from high-quality birch, beech, or hardwood through drying, resin impregnation, and high-temperature, high-pressure lamination processes. It possesses excellent mechanical strength and electrical insulation properties and is commonly used in the following components:

Winding axial and radial supports

Coil clamping structures

Oil passage spacers and pads

Insulation structures between the core and windings

Clamping and fixing support components

This material has good machinability and can be precision machined according to drawings, including turning, milling, drilling, and grooving.

Performance Advantages of Electrical Laminate Wood

1. Excellent Mechanical Strength

Electrical laminate wood possesses excellent compressive, bending, and impact resistance.

2. Stable Electrical Insulation Properties

This material has high dielectric strength and stable insulation resistance.

3. Good Oil and Heat Resistance

Electrical laminate wood maintains stable performance even after long-term immersion in transformer oil.

4. Strong Processing Adaptability

This material can be customized according to customer drawings to meet the needs of complex structural components.

Common Standards for Electrical Laminate Wood

Electrical laminate wood for transformers typically conforms to the following international and industry standards:

IEC 61061

IEC 60641

GB/T 20631

DIN 7707

ASTM D202 

When purchasing electrical laminate wood, it is essential to specify the standard number and version to ensure that the material performance meets project requirements.

Advantages of Bulk Procurement from Professional Suppliers

Bulk procurement of electrical laminated wood not only involves cost control but also relates to production stability and product quality. Professional suppliers can provide the following support:

1. Consistent Quality and Traceability

From wood selection to impregnation, hot pressing, and post-treatment, professional suppliers can strictly control each stage to ensure consistent performance of every batch. They can also provide products that comply with standards such as IEC 60641 and GB/T 1303, and offer complete material reports.

2. Cost-Effectiveness

Through large-scale production and direct supply, professional suppliers can offer competitive bulk prices, helping to reduce the overall cost of large projects or long-term production.

3. Supply Stability

Professional suppliers have sufficient raw material reserves and efficient production arrangements, enabling them to deliver the required specifications and quantities of materials on time, ensuring continuous production.

4. Pre-sales Technical Support

Professional suppliers can recommend appropriate material grades and specifications based on actual application requirements such as heat resistance, mechanical strength, and environmental conditions, avoiding problems caused by improper selection.

Our Core Customization Services

When standard products cannot meet design needs, we offer the following customization services:

Size and Shape Customization

We process non-standard sizes of boards, strips, blocks, and irregularly shaped insulation components such as grooved, drilled, and stepped parts according to customer drawings, reducing subsequent processing steps for customers.

Performance Parameter Customization 

Based on insulation and mechanical requirements, we adjust resin formulations and processes to customize indicators such as density, dielectric strength, flexural strength, and parallel-layer withstand voltage.

Heat Resistance Grade Customization 

We offer products in multiple grades, including E, B, F, and H, and these products are suitable for various scenarios from oil-immersed transformers to dry-type transformers.

Pre- and Post-treatment Customization 

We provide moisture-proofing, surface polishing, and pre-impregnation processes to meet specific production and environmental requirements.
