Earthing conductors connect all of the non current carrying parts of an electrical system, or any metallic parts in the vicinity of the electrical system together. These parts include conduits, enclosures, supports and other metallic objects.
This earthing system has two purposes:

1. Safety. The earthing conductor system provides a low impedance path for fault currents to flow. This allows the full current to be detected by overcurrent protective devices (fuses and circuit breakers), safely clearing the fault quickly.

2. Power quality. The earthing system allows all equipment to have the same reference voltage. This helps electronic equipment operation and helps prevent the flow of  extraneous current on communication lines, seals and other connections.

3. Other applications include broadcast equipment safety and RF grounding;  Audio equipment grounding to exclude earth loop faults and extraneous energy hum.  I.T. applications such as rack -mounted server systems need clean, tight earth bonds in order to eliminate spurious signals which can cause spikes in data transfer, resulting in corrupted computer files.

Earthing conductors include earth leads, earth cable, earth braids and connectors.

Tranect earth braids offer maximum flexibility, and are vastly superior to standard cable connections. The properties of flexible earth braids are important in applications where movement or vibration is present, i.e. across door hinges or the runners of rack-mounted electrical equipment.

Tranect earth braids are made from high conductivity electrolytic copper, and are tinned to prevent oxidation and galvanic reaction when connected to other metal surfaces like steel and aluminium.
