​1、 Basic Definition Electrical Insulation Precompressed Pressboard is a high-density cellulose insulation board made from high-purity unbleached kraft coniferous wood pulp and pre compacted at high temperature and high pressure. It belongs to Class A heat-resistant insulation material and is specifically suitable for oil immersed high-voltage electrical equipment.

​ The core of the Electrical Insulation Crepe Paper Tube is flexible and folding resistant, with strong oil immersed insulation, good heat dissipation, high temperature resistance, chemical stability, and easy installation. It is specially designed for the insulation of high voltage leads, tap changers, and windings of oil immersed transformers/reactors.

This material relies on the characteristics of voltage equalization, anti corona, flexible coating, and oil resistant insulation, and focuses on optimizing the electric field and insulation protection of high-voltage transmission and transformation equipment. Its core applications are as follows:

Polyester Silicone Adhesive Tape​ (PET silicone tape) core is used for high temperature shielding, electronic insulation, difficult to stick surface bonding, industrial connection, temperature resistance -40 ℃ to 220 ℃, no residue after tearing off.

Polyimide Fiberglass Laminated Sheet is a high-performance composite material that is resistant to high temperature, high strength, insulation, flame retardancy, and corrosion. It is mainly used in special scenarios such as high temperature/fire prevention/insulation/corrosion prevention/high strength in buildings. It is less commonly used in ordinary civil buildings and more commonly used in industrial buildings, special buildings, and public safety facilities.

Polyimide Film Mica Tape is a type of H-grade/200 grade high-temperature resistant insulation composite material, which is mainly used for the main insulation and wrapping insulation of high-end motors, high-voltage frequency conversion equipment, fire-resistant cables, and high-temperature electrical components.
