BusBar For Eaton
BusBar for Eaton is based on high-purity copper and are divided into three mainstream types: bare copper bar (no surface treatment), nickel-plated copper bar, and galvanized copper bar. They have excellent conductive properties, mechanical strength, and environmental adaptability. They are different from ordinary copper bar. Its dimensional accuracy, surface technology, adaptation compatibility, and long-term stability all meet Eaton's global quality standards. It is the preferred conductive busbar for industrial-grade power systems.

Product Introduction
BusBar for Eaton is a solid metal conductor with high conductivity. They are made of T2 copper (copper content ≥99.9%) or TU1 oxygen-free copper base material. They are precision-processed and formed. The cross-sections are mainly standard rectangular, and the corners are rounded and passivated. Special-shaped cross-sections (L-shaped, T-shaped, ladder-shaped, etc.) can be customized according to Eaton equipment interface requirements. They are essentially for high-current power transmission. "Vessels" are responsible for the collection, distribution and conduction of electrical energy inside equipment, equipment rooms and power distribution systems.
Material advantages
Conductivity stability
We use low-oxygen copper rods for rolling, with extremely low impurity content, which avoids the problem of loose connections caused by the common "thermal expansion coefficient mismatch" of aluminum rows or Low Voltage BusBar.
Creep resistance
Copper has better creep resistance than aluminum during thermal expansion and contraction cycles, which means that the bolted connection points can still remain tight after several years of hot and cold cycles and are less likely to cause overheating risks for AC BusBar.
Adhesion of the surface treatment layer
Our coating is not simply soaked, but ensures that the coating forms a metallurgical bond with the base material to avoid peeling (peeling) of the coating during bending or punching, thereby ensuring long-term low resistance of the contact surface.
Detailed display
Surface details
Bare copper bar: The surface is as smooth as a mirror, without scratches, oxidation spots, or burrs, and has a delicate touch to ensure good contact.
Nickel-plated/galvanized copper bar: The coating is uniform and bright, with no leakage, no peeling, no bubbles, complete corner coating coverage, and consistent corrosion resistance.
Cross-sectional details
The cross-section is smooth and regular, with standard rounded corners (R2-R3), no burrs, no sagging corners, and uniform thickness, ensuring a tight fit with the device interface during installation and maximizing the contact area for battery bus bar.
Bending details
The bending angle is precise (tolerance ±1°), without cracks, wrinkles, or deformation. The stress at the bending point is dispersed to ensure mechanical strength and avoid breakage during long-term use for Positive Bus Bar.
Hole location details
The installation hole position is precise, the hole diameter is consistent, the hole wall is smooth and burr-free, and the spacing tolerance is controlled within ±0.1mm, ensuring a perfect match with the Eaton equipment fixing bolts, and the installation is firm and not loose for Negative BusBar.
Technical characteristics & production process
Every process affects contact resistance.
Precision blanking and punching
Using a CNC busbar machining center, the punching position tolerance is ≤±0.1mm, and the cumulative error of adjacent hole spacing is ≤0.2mm/meter, ensuring complete alignment with Eaton busbar connectors, insulating partitions, and bolt group holes to avoid installation stress causing insulator rupture or joint heating.
01
Chamfering and deburring
All corners are rounded and blunted with R1-R2 to remove punching burrs to prevent cutting the operator's fingers during installation. More importantly, it avoids tip discharge and local electric field concentration to improve electrical gap utilization for PCB Bus Bars.
02
Pre-treatment of surface treatment
Chemical degreasing + micro-etching polishing before plating to ensure the bonding strength of the plating. The Solid Copper Bus Bar undergoes anti-oxidation passivation to maintain the true color of the copper during storage and transportation, reducing the user's wiping and cleaning work after arrival.
03
Bending process
CNC hydraulic bending is used, the minimum bending radius is ≥2t (t is the thickness), and the bending angle tolerance is ±0.5° to avoid micro-cracks in the bending area. For the Copper BusBar for Siemens, we provide post-annealing bending processes to eliminate internal stress and prevent fatigue fracture under long-term vibration.
