The range of ZANDZ grounding conductors with PVC insulation was supplemented with new models of different types and cross-sections that you can use in the organization of grounding devices.
The new models are presented in three versions (types):
Conventional single core seamless copper wire cross-sections from 16 to 70 mm2. This model is perfect for the connection of the ground conductor with the main grounding bus (MGB) when it is not required to subject the conductor to strong bends when laying it into the ground and elements of the building facade.
Stranded copper wire with the cross-section from 10 to 120 mm2. Saying "stranded" we meant separation of one core to a few thick cores. It is a more flexible cable, as compared to a single core.
Single-core flexible presents itself a cable with one core, cross-section from 4 to 195 mm2, which is divided into a plurality of thin wires, which gives it a high grade of flexibility (up to 4). This model is often used in cases when for the connection of the MGB and and the ground electorde, the conductor must pass through a difficult sinuous path, for example, through the wall of the building.
When choosing a model and cross-section of the conductor, follow the requirements of GOST and other regulatory documents.
A one-core conductor press-fitted for an easy connection to the MGB is still the most popular model. These are ready-segments of the cable 3, 5 and 10 meters long with the existing copper tinned lugs for D8 bolt.
