Technical process
Substrate Selection and Pre-treatment: High-purity copper substrate is selected as the basic raw material for the core conductor of the PA66 Plastic Insulation Busbar. Acid pickling and polishing processes remove surface oxide layers and impurities, ensuring the cleanliness and flatness of the substrate, laying a solid foundation for subsequent processing steps.
Precision Forming and Machining: Laser cutting, CNC machining, and bending processes are used to process the copper substrate into the required 4-pole, three-phase fork structure, precisely controlling dimensional accuracy to ensure compatibility with subsequent assembly and power distribution equipment requirements.
Surface Treatment and Electroplating: Gold, silver, and nickel plating processes are used as needed to treat the conductor surface, improving oxidation and corrosion resistance, while enhancing conductivity stability for use in complex operating conditions for PP Plastic Insulation Busbar.
Insulation Coating: An integrated coating process is used to tightly coat the conductor surface with specialized insulating material, strictly controlling the insulation layer thickness and uniformity to ensure high-voltage insulation performance and strengthen the Pole 4 Phase Pin Type Insulated Busbar's safety.
Precision Welding and Assembly: Laser welding and diffusion welding are used to weld 6 Module Insulated Prong Busbar components, and American PEM fasteners are used to complete the overall assembly of the product, ensuring a tight fit and structural stability at all connection points, and guaranteeing the continuity of electrical conductivity.
Comprehensive Inspection Before Shipment: Finished products undergo multi-dimensional testing for conductivity, insulation performance, dimensional accuracy, corrosion resistance, etc., rejecting defective products to ensure that all Insulated Busbar Pin Type performance meets industry standards and engineering requirements, guaranteeing the quality of delivered products.

Technical parameters
Conductor Resistance: The product's copper busbar resistance is ≤0.00001Ω. This excellent low-resistance characteristic minimizes high-voltage transmission power loss, meeting the core requirements of efficient power distribution.
Voltage and Current Compatibility: The PA66 Plastic Insulation Busbar is compatible with load voltages from 3500VDC to 5000VDC and load currents from 100A to 2000A, accurately matching high-voltage power distribution scenarios in new energy industries and meeting the needs of various operating conditions.
Assembly Fixtures: The PP Plastic Insulation Busbar is compatible with American PEM stainless steel nuts, studs, brackets, screws, etc., simplifying the engineering assembly process and improving the compatibility between the product and power distribution equipment.
(Note: Specific parameters can be designed and customized according to customer product requirements)
