So if the speed of propagation have to be high, the capacity and inductance of the cable must be both very low. It follows that presents a low capacitance cable with high propagation speed and low inductance and therefore it is preferable.
The cables Low-Capacity differ compared to conventional cables for their constructive peculiarities, the insulation compounds (polyolefins) and the compositional geometries. So from the point of view of this range of cables it is able to ensure a low operational capacity and thus enormously limiting the overvoltage spikes often cause damage to connected equipment.
Finally, these cables are destined for the European market (CE) to North American and Canadian markets (UL/CSA).
