Products Description
Insulation Laminated Wood is a high-strength insulating material developed specifically for the electrical industry. It consists of multiple layers of high-quality birch wood, impregnated with epoxy or phenolic resins and laminated under high temperature and pressure. This material combines mechanical strength with insulating properties and is widely used in power equipment such as transformers and motors.
Procurement Parameter Confirmation Checklist (for customer reference):
1/Application: Dry-type/oil-immersed transformer? Motor? High-voltage switchgear?
2/Insulation class requirement: A/B/F?
3/Is special shaping required?
4/Load-bearing structure or just a gasket?
5/Working environment humidity and temperature?
6/Purchase quantity (m³/unit/ton)?
7/Is a test report required? (e.g., CTI, insulation resistance, flexural strength)
Product advantages:
2. Good heat resistance: Insulation laminated wood has a high thermal deformation temperature and thermal stability, can be used in high-temperature environments, and is not easy to deform or burn.
3. Good corrosion resistance:
Insulation laminated wood has good water resistance, acid resistance, alkali resistance, and oil resistance. It can be used in various chemical media and is not easily corroded or aged.
4. High mechanical strength:
Insulation laminated wood has high compressive strength, bending strength, and impact resistance, can withstand large mechanical loads, and is not easy to break or shatter.
5. Strong plasticity: Insulation laminated wood has good plasticity and processability. It can be pressed into products of various shapes and sizes through molds, and can also be secondary processed through cutting, drilling, grinding, etc. Product advantages:
