Carbon material for grounding
Carbon material for grounding (UMZ-2.2) (ICM-2.2)
It is used to reduce the spreading resistance of the potentials of lightning-protective and functional-working ground loops, which is a product of the processing of carbon materials based on coke breeze and is intended for use as a backfill of grounding devices of ground loops.
Characteristics of carbon material for grounding (UMZ-2.2) (ICM-2.2):
|C, no less than||Ash, no more than||S, no more than||Moisture, no more than|
The average electrical resistivity for the material corresponds to 2.2-2.8 Ohm / m. Lower resistance values are possible, it is applied at the request of the customer
Fraction – up to 40 mm or as agreed
The effect of using carbon material
Due to the larger fraction of UMZ, in comparison with other grounding materials, the service life of the material increases and strength grows, which is especially important for use in construction projects for special purposes.
