| | | The cable volume Is an Important criterion for the selection of the required trunklng size of the underfloor system. As the cables are never packed tightly together or are absolutely parallel, It is not enough to base the volume calculation solely | | on the cable diameter. A realistic calculation is provided by the formula (2r)2. To simplify your work, we have listed the diameters and space requirements of the most important cable types on this double page. Important: the values are average val- | | ues, which may vary between manufacturers. Please refer to the manufacturer's specifications for the exact values. | | |
