The black cable reel with a length of 5 metres is a specific accessory for earthing sets from the brand Chauvin Arnoux. It is an H-reel fitted with a black wire, intended for use in 3-pole or 4-pole earthing sets as well as for resistance measurements. The cable serves as a connecting element between measurement points and the measuring device, with the black colour indicating its function as an earthing conductor, commonly used in electrical engineering for the protective earth (PE) conductor.

Cable reel
The cable reel is mounted on an H-reel, enabling compact and orderly storage of the 5-metre cable. The H-reel ensures the cable does not become tangled or damaged, which is particularly advantageous during frequent field use. Using an H-reel also facilitates easy unwinding and rewinding of the cable, improving operational handling efficiency.

Applications
The cable is specifically designed for earthing sets used in electrical installations and safety measurements. It is used in 3-pole and 4-pole earthing sets to measure earthing resistance. Use in 4-pole systems allows for more precise measurements, as current and measurement lines are separated, minimizing interference from the measurement current. The cable is also suitable for use with resistance measuring instruments, particularly in combination with the Pylon Box CA 6474, which features an ES socket.

Functions and equipment in detail
The cable is black, which in electrical engineering is the standard marking for the protective earth (PE) conductor. The 5-metre length provides sufficient reach for connecting between the measuring device and the earthing point, without being too short or too long. The H-reel ensures structured storage and prevents mechanical damage to the cable from twisting or overloading. The cable is designed for use in earthing sets, which are commonly used in industrial or technical installations.

Technology explained simply
The H-reel is a mechanical component that holds and stabilizes the cable. It enables easy handling and prevents damage to the cable during transport or storage. The black cable itself is a conductor used for transmitting measurement currents in earthing installations. The black colour is not only visually distinct but also complies with standards for protective earth conductors in electrical installations. The 5-metre length is sufficient for flexible use in various measurement tasks, eliminating the need for additional extensions.

Compatibility and accessories
The cable is specifically developed for use with earthing sets from the brand Chauvin Arnoux. It is compatible with 3-pole and 4-pole earthing sets, as well as with resistance measuring instruments featuring an ES socket. It is particularly intended for use with the Pylon Box CA 6474, which serves as an accessory for earthing measurements. The ES socket enables a secure and reliable connection between the cable and the measuring device, ensuring measurement accuracy.

Installation and mounting
Mounting of the cable involves simply unwinding it from the H-reel and connecting it to the relevant measurement points. The connection is made via the ES socket, which is integrated into the Pylon Box CA 6474. The H-reel remains attached to the cable and serves as a storage element. No special tools or additional mounting equipment are required. Installation is performed directly at the measuring device or earthing installation, with the black colour indicating its function as a protective earth conductor.

An earthing set is a measuring system used to determine earthing resistance in electrical installations. The use of 4-pole systems enables more precise measurements, as current and measurement lines are separated. The cable is an integral part of such systems, as it establishes the connection between the measuring device and the earthing point. The H-reel ensures structured storage and facilitates handling during operation.

Advantages in operation
The cable reel provides a reliable and robust connection for earthing measurements. The H-reel ensures orderly storage and prevents mechanical damage. The 5-metre length offers sufficient flexibility for various measurement tasks. The black colour complies with standards for protective earth conductors and simplifies identification during operation. Compatibility with the Pylon Box CA 6474 and other earthing sets from the brand Chauvin Arnoux ensures seamless integration into existing measurement systems.
