PP Plastic Insulation Busbar
Products Description
The PP Plastic Insulation Busbar is a highly integrated busbar connection component specifically designed for circuit breakers. Its typical structure features a 4-pin high-purity copper conductor embedded in a flame-retardant PP engineering plastic shell, with a functional silver plating layer applied to critical contact areas. This product is specifically designed for low-voltage power distribution systems, energy storage battery cluster protection units, and photovoltaic DC combiner boxes, integrating conductivity, insulation, structural support, and safety protection into one unit. Through precision insert injection molding, zero-gap coverage between the copper busbar and the PP shell is achieved, ensuring an ultra-high conductivity of ≥97% IACS while providing IP20-level protection against electric shock and excellent arc isolation capabilities. As a core interface component at the input/output terminals of circuit breakers, its reliability directly affects the safety level and maintenance costs of the entire power distribution system.
Production Process and Flow
Raw Material Inspection
High-purity copper rods conforming to standards such as GB/T2Y2 are selected, and impurities are strictly controlled for Pole 4 Phase Pin Type Insulated Busbar.
01
Forming and Processing
The copper rods are stamped and bent into the geometric shapes required for the 4 Pole Three-Phase Fork-Style Insulated Busbar, and mechanical deburring is performed.
02
Surface Silver Plating
An electrolytic silver plating process is used to form a uniform silver plating layer on the copper surface. The silver layer thickness is controlled within the industry-recommended range to prevent 6 Module Insulated Prong Busbar oxidation.
03
Injection Molding
The processed copper body is placed into an injection molding machine mold, molten PP plastic is injected, and after cooling and solidification, the outer shell is formed for Insulated Busbar Pin Type.
04
Quality Inspection
Resistance testing, insulation withstand voltage testing, and dimensional tolerance inspection are performed to ensure that each Pole 4 Phase Pin Type Insulated Busbar meets the technical specifications.
05
Technical Features and Manufacturing Process
Injection Molding Housing Technology
Advanced injection molding technology is used to create the housing, achieving high-precision molding and excellent sealing. PP plastic possesses excellent insulation properties, chemical corrosion resistance, and heat resistance, effectively protecting the electrical components inside the 4 Pole Three Phase Fork Style Insulated Busbar and preventing external environmental influences on the electrical connection.
4-Pin Structure Design
The unique 4-pin structure meets the diverse electrical connection needs of circuit breakers, enabling parallel transmission of multiple currents. This design not only improves the efficiency of the electrical connection but also enhances the system's flexibility and scalability for Insulated Busbar Pin Type.
Surface Silver Plating Process
Surface silver plating significantly improves the 6 Module Insulated Prong Busbar's conductivity and corrosion resistance. Silver has extremely high conductivity and good chemical stability, maintaining the busbar's performance stability in harsh environments and extending its service life.
