Bakelite sheet is widely used in the internal insulation components of the inverter, such as partitions and brackets, which can accurately isolate circuits with different potentials and effectively prevent electrical breakdown and short circuit failures. At the same time, its excellent heat resistance enables it to adapt to the high temperature environment generated by the long-term operation of the inverter, ensuring stable and reliable operation of the equipment and providing solid guarantee for the safe and efficient operation of the photovoltaic power generation system.

3. Photovoltaic tracking system component support

In order to improve the power generation efficiency of photovoltaic power stations, more and more power stations have adopted photovoltaic tracking systems. With good mechanical strength and wear resistance, bakelite sheet is used to manufacture mechanical transmission and support structure components such as gears, sleeves, and brackets of the tracking system. These components can ensure the stable operation of the tracking system, effectively reduce component wear, and reduce failure rate and maintenance costs. According to actual application data, the maintenance cycle of the photovoltaic tracking system using bakelite sheet components has been extended by 30%, and the overall operating cost has been reduced by 20%.

Important applications in the field of wind power generation

1. The key role of stator and rotor insulation of wind turbines

As the core equipment of the wind power generation system, the insulation performance of the stator and rotor of the wind turbine directly determines the efficiency and reliability of the generator. Bakery boards are often processed into insulating gaskets, slot wedges and other components to isolate the winding and the core, effectively prevent current leakage and eddy current loss, and significantly improve the energy conversion efficiency of the generator. Its excellent heat resistance and corrosion resistance enable it to operate stably for a long time in harsh natural environments such as wind, sun, and high humidity, ensuring the continuous and efficient power generation of the wind power generation system.

2. Internal insulation protection of wind power converters

Wind power converters are responsible for converting the unstable alternating current generated by wind turbines into stable electric energy and incorporating it into the power grid. The internal high-voltage circuits have extremely high requirements for insulation protection. Bakelite sheet is used to make insulating partitions, busbar clamps and other components inside the converter, providing reliable insulation protection for the circuit and effectively reducing the probability of electrical failures. In addition, the flame retardant properties of bakelite sheet fully meet the strict standards of the wind power industry for equipment safety, safeguarding the safe operation of wind power converters.

Wide application in the field of energy storage

1. Insulation protection of battery management system (BMS)

In energy storage battery systems, the battery management system bears the heavy responsibility of accurately monitoring and managing the battery charging and discharging process, and its reliability is crucial. Bakelite sheet is widely used in BMS circuit board insulation support, terminal insulation sheath and other components. With its excellent insulation performance, it effectively prevents short circuits between components with different potentials inside the battery pack, protects the BMS circuit board from electrical breakdown damage, greatly improves the stability and reliability of the battery management system, and ensures the safe and efficient operation of the energy storage battery system.

2. Structural support for energy storage battery modules

Energy storage battery modules are composed of multiple battery cells and require strong and reliable structural parts for fixing and supporting. Bakelite sheet can be processed into structural components such as end plates and side plates of battery modules. It can not only provide sufficient mechanical strength to ensure the structural stability of battery modules during transportation and use, but also has good insulation performance, effectively avoiding electrical interference and short circuit risks between battery cells. At the same time, its chemical corrosion resistance enables it to resist the erosion of chemical substances such as battery electrolyte, significantly extending the service life of battery modules.
