Selection and Installation Guide
1. Key Selection Factors
Current and Voltage Requirements: Select specifications that match the system load (100A-2000A) and operating voltage (3500VDC-5000VDC).
Environmental Adaptability: Consider factors such as temperature, corrosive gases, and vibration to select appropriate coating and insulation materials.
Space Constraints: Customize flat or three-dimensional structures to fit the internal layout of the equipment.
2. Installation Specifications
Contact Surface Treatment: Clean the Laminated Busbar Connectors and equipment contact surfaces with alcohol before installation to ensure a low-resistance connection.
Securing Method: Use stainless steel clamps with a torque of 0.6-1.0 N·m to avoid deformation caused by overtightening.
Regular Testing: It is recommended to test the ground resistance every 6 months to ensure a value of ≤0.00001Ω.
