Product Introduction
Busbar Insulation Paint is a core insulation component for high-voltage power distribution systems in the fields of new energy and power electronics. It is specifically designed for conductive substrates such as copper bars. Through precise material formulation and standardized coating process, it forms a dense insulation layer on the surface of the busbar, balancing high conductivity conduction with reliable insulation protection. It is suitable for high voltage conditions of 3500VDC to 5000VDC and high current conditions of 100A to 2000A. Its core value lies in providing engineering procurement and system engineers with a full-chain insulation solution that is "technically compatible, reliable in the long term, consistent in batches, and controllable in supply". It supports the efficient and stable operation of new energy vehicles, photovoltaic energy storage, power appliances and other scenarios, and helps to achieve cost reduction, efficiency improvement and sustainable development goals.
Process Flow
Substrate Pretreatment
Copper and aluminum busbar substrates undergo standardized treatment including degreasing, rust removal, and drying to remove impurities and oxide layers, improving cleanliness and laying a solid foundation for stable coating adhesion, thus avoiding delamination and blistering.
Insulating Varnish Formulation
Insulating varnish is precisely formulated according to standard recipes to match engineering conditions, strictly controlling viscosity and component uniformity. After degassing, batch-to-batch consistency in insulation performance and coating effect is ensured for Busbar Epoxi Powder Coating.
Precise Coating Operation
Automated equipment is used, and corresponding coating processes are selected based on busbar specifications. Coating thickness is precisely controlled, and parameters are monitored throughout the process to ensure a dense, uniform coating free of appearance and performance defects.
Curing and Inspection before Shipment
The Busbar Coating with Epoxy Coating Powder undergo standardized curing treatment to enhance coating adhesion. Multiple tests are conducted to eliminate substandard products, ensuring that products meet international standards before shipment.
