Description

Products Description

Laminated wood for transformer is a special material widely used in the field of electrical engineering.

It is usually made of high-quality wood through special treatment and lamination processes. Its main advantages are its good insulating properties and mechanical strength, making it an important material in the manufacture of electrical equipment.

Product advantages

1. Excellent processing performance
Easy to turn, drill, mill and punch, can be processed into various structural parts according to drawings, suitable for mass customization.

2. Environmentally friendly and sustainable
Using natural wood as the basic raw material and resin as the adhesive, it meets environmental protection requirements, and some products can meet ROHS, REACH and other standards.

3. Reasonable cost control
Compared with all-resin or polymer insulation materials, electrical laminated wood has a higher cost-effectiveness while ensuring performance, and is suitable for large-scale purchases.
