10mm-100mm Electrical Laminated Wood | Laminated Wood Components | High-Voltage Insulation Structural Components

In the power equipment field, high-voltage insulation performance is crucial for the safe and stable operation of equipment. 10mm-100mm electrical laminated wood, as a high-performance composite insulation material, combined with customized laminated wood components, is a key component in high-voltage insulation structures. It possesses excellent electrical insulation properties, high mechanical strength, ease of processing, and good environmental adaptability. It is widely used in electrical equipment such as transformers, switchgear, and reactors to ensure the normal operation of power systems.

10mm-100mm Electrical Laminated Wood Overview

Electrical laminated wood is made from high-quality birch, beech, and other hardwood veneers. After drying, it is impregnated with high-performance insulating resin (such as phenolic resin or epoxy resin). Then, according to process requirements, the veneers are stacked in a cross-grain or longitudinal-grain manner. Finally, it is pressed under high temperature and pressure to produce high-performance engineered wood products.

Its specifications range from 10mm to 100mm, meeting the thickness requirements of most high-voltage insulation scenarios. From thin insulating partitions to thick load-bearing supports, it can precisely adapt to various applications of electrical equipment.

Compared to ordinary solid wood or ordinary insulation materials, 10mm-100mm electrical laminated wood avoids defects such as knots and cracks found in solid wood through its laminated structure. Its performance is more stable and uniform.

Electrical Laminate Wood Specifications: Full Thickness Coverage from 10mm to 100mm

We offer a full range of electrical laminate wood with thicknesses ranging from 10mm to 100mm to meet different voltage levels and structural load-bearing requirements.

10mm - 30mm (Thin): 

Suitable for partitions, pads, and insulating supports in high-voltage switchgear. The material in this thickness range has moderate flexibility, suitable for die-cutting and precision carving. It provides reliable electrical isolation in confined spaces.

30mm - 60mm (Medium): 

Widely used in insulating sheets at the ends of transformer coils and grounding plates for iron cores. At this thickness, the material must withstand significant mechanical pressure and electrical stress simultaneously. Our laminate wood undergoes a special thermosetting process to ensure uniform density throughout, preventing delamination and cracking.

60mm - 100mm (Thick): 

Specifically designed for ultra-high voltage transformers, large generator sets, and heavy-duty high-voltage equipment. As the main insulating structural component, this type of thick sheet can replace traditional steel structural components, reduce equipment weight, and solve the problem of eddy current loss in metal components under high magnetic fields.

Customized 10mm-100mm Laminate Wood Parts 

Standard sheet materials often cannot directly meet the complex industrial design requirements. As a professional insulation component supplier, we offer one-stop deep processing services for laminate wood parts.

We can process 10mm-100mm electrical laminate wood into various complex shapes based on customer-provided drawings (CAD or PDF):

Precision Milling and Drilling: 

Machining high-precision mounting holes, grooves, and stepped surfaces.

Using CNC machining centers, we ensure hole diameter tolerances are controlled within ±0.1mm, guaranteeing a tight fit with metal electrodes or clamps.

Turn and Irregular Shaped Parts: 

We provide turning services for rotating structures such as circular pads and cylindrical supports.

For non-standard irregular shaped structures, we achieve burr-free cutting using waterjet or laser cutting (suitable for thin sheets).

Surface Treatment and Post-Curing: 

For parts processed for use inside oil-immersed transformers, we perform rigorous drying and surface painting (or impregnation) treatments. This ensures that it does not absorb moisture or release impurities in the transformer oil, thus maintaining stable insulation performance over a long period.

Applications of Electrical Laminated Wood and Processed Parts

Transformer Industry: 

In power transformers with voltage levels of 110kV and above, the insulation sheets at the winding ends are key components that withstand short-circuit electrodynamic forces.

High-Voltage Switchgear: 

In gas-insulated switchgear (GIS) or air-insulated switchgear, laminated wood processed parts are often used as busbar support insulators and contact box mounting plates.

Electric Machines and Generators: 

In large hydroelectric generators or wind turbine generators, electrical laminated wood is used for structural components such as stator end cone rings and supports.

Whether it's standard 10mm-100mm electrical laminated wood sheets, high-precision laminated wood processed parts, or high-voltage insulation structural parts for ultra-high voltage applications, we are committed to providing customers with high-performance insulation solutions.
