Description:
Our electrical insulation material is precision-engineered to serve
as high-performance bracing for transformers, providing superior
electrical insulation, structural integrity, and long-term
operational stability. The insulation board features an
exceptionally smooth surface with minimal imperfections, ensuring
safe and straightforward installation. Its excellent moisture and
humidity resistance safeguards transformer components consistently,
even in challenging environments. Lightweight yet mechanically
robust, the board offers outstanding durability to endure daily
operational stresses while maintaining ease of handling and
assembly.

Applications:
Electrical Insulation rod, bone mold, board are widely employed
across various electrical applications due to its excellent
insulating and protective properties.
- Transformers: It insulates the windings from the core, reducing the
risk of electrical arcing and contributing to efficient transformer
operation.
- Motors: The board provides insulation between the windings and
motor housing, helping prevent electrical arcing and supporting
motor efficiency.
- Circuit Breakers: It serves as an insulating barrier between
contacts, reducing arcing and promoting reliable performance.
- Power Cables: Used as an insulating layer, it safeguards cables
against moisture and other environmental factors to extend service
life.
