PVC Insulated Copper Busbar For Electrical Connections
PVC Insulated Copper Busbar for Electrical Connections is a high-conductivity copper busbar with a special dip-coating process that forms a uniform, dense PVC protective layer with excellent insulation properties on the conductor surface. This gives the busbar both high-efficiency conductivity and electrical insulation protection. This product is widely used in new energy vehicle battery packs, high-voltage distribution units (PDUs), energy storage systems (ESS), photovoltaic inverters, power equipment, industrial control cabinets, and high-voltage DC systems, and is one of the key conductor components in modern new energy electrical connection systems.

Product Introduction
PVC Insulated Copper Busbar for Electrical Connections are electrical connectors manufactured using high-purity copper as the conductor through precision stamping, bending, and PVC dipping.
Compared to traditional bare copper busbars, their biggest advantages are:
Integrated conductivity and insulation
Reduced the number of internal insulation components
Improved installation safety
Optimized equipment space utilization
Enhanced overall system reliability
The PVC coating not only provides insulation protection but also reduces the impact of environmental corrosion, mechanical wear, and external contamination on the busbar's performance.
Design advantages
Compact layout
The insulation layer allows for smaller electrical clearances, optimizing space utilization inside the battery pack or inverter.
01
Vibration-absorbing buffer
The moderate flexibility of the PVC layer effectively absorbs vibration impacts and protects the connection points from loosening or fatigue breakage.
02
Modular interface
Reserved standard or customized holes and plated terminals to facilitate quick assembly and later expansion.
03
Thermal management optimization
The excellent thermal conductivity of copper, combined with the insulating layer design, helps heat spread evenly and reduces the risk of local hot spots.
04
Logo-friendly
Colors or markings can be customized to facilitate on-site identification and maintenance management.
05
Detailed Display and Quality Control
R-corner Chamfering
All Battery Bus Bar cut edges undergo precise rounding. This is not only to prevent puncturing the insulation layer but also to eliminate corona discharge and ensure uniform electric field distribution.
Matte Surface Texture
Unlike glossy plastic, our PVC-coated surface has a matte or semi-matte finish, providing anti-slip and wear-resistant properties. It also does not produce visual glare under strong light, facilitating maintenance and inspection.
End Sealing Process
The exposed parts (contact surfaces) of the Tin Coated Insulated Flat Copper Bus Bar for Battery ends are tin-plated or silver-plated, and the junction between the insulation layer and the conductor undergoes special sealing treatment to prevent moisture from seeping into the insulation layer through capillary action.
Material Advantages: Synergistic Enhancement of High-Conductivity Matrix and Modified PVC
Low-Oxygen, High-Conductivity Copper Substrate: We meticulously select high-purity copper with fine grains and extremely low oxygen content as the conductive core, ensuring extremely low DC resistance and thermal resistivity. Under continuous high-current loads, the low heat generation characteristics of the copper matrix slow down the thermal aging process of the external PVC insulation layer, extending the PVC Dipping Nickel Plated Copper Bus Bar for EV Battery lifespan from the inside out.
High-Impact and Weather-Resistant Modified PVC: Abandoning general-purpose materials, we use customized modified PVC powder. By introducing nano-level rigid particles for toughening and highly efficient composite stabilizers, the cured insulation layer does not crack in extreme cold of -40℃ and does not soften or melt under long-term heat of +105℃. For photovoltaic applications, highly efficient UV absorbers are added to inhibit the photo-oxidative degradation of polymer chains, ensuring that the insulation layer does not whiten or powder under long-term outdoor exposure.
