Busbar Insulator
Products Description
The busbar insulator (also known as insulated busbar) is a core electrical component designed for conductive connection and electrical isolation. Its base material uses high-conductivity copper or aluminum (optimized for efficient current transmission), paired with flame-retardant insulating materials like epoxy resin or heat-shrinkable sleeves (to ensure electrical safety). For surface treatment, the metal base undergoes tin-plating or nickel-plating (to enhance corrosion resistance and conductivity stability), while the insulating layer is applied via molding or heat-shrink processes for uniform, high-strength insulation. This car battery bus bar is widely used in low-voltage electrical devices (switches, relays, contactors, circuit breakers) and new energy equipment (energy storage lithium batteries, film capacitors, photovoltaic inverters), serving as a critical part for stable circuit operation.
Manufacturing Process
The production of auto bus bar follows a standardized, precision-focused workflow:
the busbar supports metal base is shaped via CNC stamping, ensuring dimensional accuracy within ±0.05mm to fit diverse device layouts.
01
the tinned copper busbar is applied through continuous electroplating lines, with a uniform coating thickness of 5-10μm to maintain long-term conductive performance.
02
the ev battery connector insulating layer is integrated with the metal conductor via automated injection molding or heat-shrink equipment, achieving an insulation withstand voltage of over 1500V.
03
each battery terminal bus bar undergoes electrical testing (insulation resistance, voltage withstand) to meet industry quality benchmarks.
