In the complex and sophisticated operating system of power plant generators, insulation materials play a vital role, and F-grade high-strength laminated glass fiber board DECJ0902 is one of the best. With its excellent performance, it provides a solid guarantee for the stable and efficient operation of the generator.

Material composition and manufacturing process

F-grade high-strength laminated glass fiber board DECJ0902 is based on electronic grade alkali-free glass fiber cloth and impregnated with high-quality epoxy resin. Alkali-free glass fiber cloth has excellent insulation properties, high mechanical strength and good chemical stability, and can effectively resist the erosion of the external environment. Epoxy resin gives the board excellent adhesion, so that during the lamination process, each layer of glass fiber cloth is closely combined to form a solid whole. During manufacturing, the glass fiber cloth impregnated with epoxy resin is stacked layer by layer according to a specific process and hot-pressed under high temperature and high pressure. This process allows the epoxy resin to fully cure, further improving the performance of the board and ensuring that it has stable and excellent characteristics.

Key performance characteristics

(I) Excellent electrical insulation performance

DECJ0902 has extremely high insulation resistance, and its volume resistivity is usually greater than 10¹³Ω・cm, which can effectively prevent current leakage and prevent electrical faults such as short circuits. Its dielectric strength is also excellent, and it can withstand higher voltages without being broken down. It can still maintain stable insulation performance under high voltage environments, providing reliable electrical isolation for the safe operation of generators.

(II) High mechanical strength

The mechanical strength of the board is extremely excellent, with a tensile strength of ≥200MPa, and some products can even reach a higher level. This enables it to withstand mechanical stress, vibration and possible external force impact during the operation of the generator, and is not prone to deformation, cracking and other damage, ensuring the integrity of the insulation structure and extending its service life.

(III) Good heat resistance

As a Class F insulating material, DECJ0902 has a heat resistance level of 155℃. Within this temperature range, the performance of the board is stable, and it will not age or degrade due to long-term heat. Even in the high temperature environment generated by the operation of the generator, it can still reliably play an insulating role to ensure the continuous and stable operation of the generator.

(IV) Good moisture resistance

The environment of the power plant is relatively complex, and the humidity changes greatly. DECJ0902 has good moisture resistance, low water absorption, and can effectively resist moisture erosion. Even in a humid environment, its insulation and mechanical properties will not be significantly affected, ensuring the normal operation of the generator under various climatic conditions.

(V) Good processing performance

The board is easy to cut, drill, grind and other mechanical processing operations. It can be processed into various shapes and sizes according to the different insulation structure requirements of the generator, which is convenient for installation and use, greatly improving the convenience of production and maintenance.

Application in power plant generators

(I) Coil insulation

The coil of the generator is the core component for generating electrical energy, and has extremely high insulation requirements. F-grade high-strength laminated glass fiber board DECJ0902 can be made into the insulation skeleton and insulation partition of the coil, which effectively isolates the coil from other parts to prevent leakage, and provides mechanical support for the coil to ensure its stable operation under the action of electromagnetic force.

(II) Slot wedge

Used to fix the coil in the stator slot of the generator, the slot wedge made of DECJ0902 has good mechanical strength and insulation performance. It can tightly fix the coil in high temperature and high electromagnetic environment to prevent its displacement, and provide reliable insulation protection to avoid short circuit between the coil and the stator core.

(III) Insulation support

As the supporting component of the internal insulation structure of the generator, the insulation bracket and pad made of DECJ0902 sheet not only provide support for other insulation components and maintain the stability of the insulation structure, but also have good insulation performance, effectively blocking the conduction path of the current and ensuring the overall insulation performance of the generator.

F-grade high-strength laminated fiberglass board DECJ0902 plays an irreplaceable role in the insulation field of power plant generators with its excellent performance. It provides a solid foundation for the safe, stable and efficient operation of generators and is an indispensable material in the power production process of power plants. With the continuous development of the power industry, the requirements for the performance of insulation materials are increasing. Driven by technological innovation, DECJ0902 is expected to continuously optimize its performance and make greater contributions to the development of the power industry.
