Grounding Busbar Tmgb Copper
The Grounding Busbar Tmgb Copper is a core component of the grounding (equipotential bonding) infrastructure of modern telecommunications and power systems. As the centralized connection point for all grounding branches, it fulfills the critical functions of safely discharging fault and lightning currents and equalizing equipment potentials. Essentially, it uses a highly conductive copper-based carrier to unify the grounding circuits of multiple devices, providing a zero-potential reference for critical scenarios such as data centers and telecommunications rooms. It serves as the "grounding hub" that ensures personnel safety and stable equipment operation.

Product Introduction
The Grounding Busbar Tmgb Copper is a critical node component in electrical systems responsible for centralizing and distributing grounding conductors. It is typically installed in equipment rooms, distribution rooms, cabinets, or computer room grounding systems for unified grounding, equipotential bonding, and overcurrent relief.
Crafted from high-purity T2 copper, this product boasts a conductivity exceeding 99.9%, ensuring low impedance and low temperature rise in high-load and multi-node grounding scenarios. The surface can be optionally treated with tin, nickel, or silver plating for corrosion resistance, ensuring long-term stable operation in humid, salt-spray, or corrosive environments.
As a core component of professional grounding system solutions, Apollo's TMGB copper busbar series is widely used in new energy storage systems, 5G communication sites, IDC data centers, high-voltage substations, and rail transit electronic control systems, providing customers with safe, reliable, and customizable electrical grounding support.
Product Structure and Design Features
| High-Conductivity Copper Main Body |
Using T2 high-purity oxygen-free copper (Cu ≥ 99.9%), this product offers low resistivity and excellent conductivity. This ensures potential equalization and current diversion accuracy within the grounding system. It offers excellent thermal fatigue resistance and mechanical strength, making it suitable for high-frequency start-stop and continuous load environments. |
| Precision Stamping and Forming Process |
The Backplane Bus Bar is formed using CNC stamping and bending, with hole position accuracy controlled within ±0.05mm. Each connection hole is deburred and chamfered to ensure a tight installation and eliminate contact resistance risks. Hole position, length, thickness, and end configuration can be customized according to customer drawings, supporting mass OEM/ODM production. |
| Surface Protection and Conductive Plating |
A variety of surface finishes are available, including tin plating, nickel plating, and silver plating. The plating is uniform and dense, with strong oxidation resistance, making it suitable for outdoor and high-humidity environments. The silver-plated version significantly improves high-frequency current conduction, meeting the needs of high-end energy storage and communications applications. |
| Insulation and Support Accessories |
Optional accessories include insulation brackets, identification labels, terminal blocks, and protective covers. Insulation components are made of high-temperature-resistant, flame-retardant PC or nylon materials, ensuring structural stability and safe isolation. The modular installation design facilitates device connection and subsequent maintenance. |
