Przewód CUI
This might apply for entrance or sheltering areas of buildings with a high visitor frequency, such as theatres, cinemas, shopping centres, where bare / uninsulated down conductors and lightning protection earth electrodes are installed in close proximity.
Protective measures against inadmissibly high touch voltages may also be requested for especially exposed (lightning endangered) buildings or structures, e.g. shelters, which are publicly available.
Touch voltage is defined as the voltage which affects a person standing on the ground in a distance of about 1 m from the down conductor touches the down conductor. Here the current flows through the hand and body down to the feet (see Figure 1).
The hazardous area for persons outside of a building is defined as 3 m around the down conductor and from ground level up to a height of approx. 3 m.
According to IEC/EN 62305-3 Subclause E.4.2.4.2, the area to be protected against touch voltage corresponds to the height at the tips of a man's fingers when he streches his arm vertically and a separation distance s (see Figure 2). Additionally, the step voltage in the surrounding of the building / down conductor has to be taken into account.
Szczegóły
The dangerous area of touch and step voltages for living beings is defined as an area of approx. 3 m around the down conductor, from ground level up to a height of approx. 3 m.The CUI conductor has a copper core and a high-voltage-resistant insulation.These conductors shall meet the requirements of a:
- Surge withstand capability of 100 kV (1.2/50 µs)
- Prevention of creeping flashover even at rain
