Product Catagories

Applications

Industrial Distribution Cabinet: centralized busbar earthing of PLC, inverter and other equipment. Enhances operator safety and equipment protection.

Telecommunications and Data Centers: telecommunications grounding busbar helps to reduce electromagnetic interference (EMI) and provide protecttion for sensitive equipment.

Lightning Protection Systems: electrical ground bar provides low-impedance path to ground for lightning current

Basic Knowledge

What is a terminal grounding busbar?

An electric ground bar with an insulating supportor that can be directly installed on the enclosure and the grounding wire is fixed by screws to ensure safety and convenience.

Safety: By providing a low-impedance path, it’s important to prevent hazards such as electric shock and fire by safely directed the fault current to the ground .

Electromagnetic compatibility: Reduce Electro-Magnetic Interference (EMI) to ensure the normal operation of the equipment.

Common misunderstandings

Ignoring material selection:  people usualy think that any conductive material is suitable for the grounding busbar. In fact, copper or brass and aluminum are widely used due to their excellent conductivity and corrosion resistance.

Improper size: Mistakenly thinking that all terminal grounding busbar are universal in size. In fact, the size of neutral bus bar should be selected according to the current load and application environment of the system.

Installation precautions:

Connection tightening: Make sure all connection points are firmly fixed by screws to prevent looseness and poor contact.

Anti-corrosion measures: In some harsh environment such as humidity or corrosion, consider using tin-plated or nickel-plated busbars.

Maintenance suggestions: Regularly check the connection condition of the grounding busbar to ensure that there is no looseness, corrosion or overheating.

FAQ

Q: Does the grounding busbar require regular maintenance?

A: Tin-plated/nickel-plated products do not require maintenance under normal conditions. It is recommended to check the plating status on electrical ground bus every 2 years in humid environments. 

Q: Does it support aluminum alloy materials?

A: It can be customized, but the conductivity is about 30% lower than that of copper. It needs to be selected according to current requirements.
