Title: Kabelspesifikasjoner AutroSafe.pdf
the shield, compared to braid. This type of shield is rarely used. A shield made of weaved wires. This is the most common method for shielded cables, it makes the best price / performance. A double layer of braid is often used to increase the attenuation, this is especially effective at cable lengths above 0,03 of the frequency wavelength, which is 70 m at 133kHz (PowerLoop). A mechanical protection of the cable, normally a rigid braid inside the outer isolation. If the armour supports proper electrical conductance and shield coverage, this may be used as one of the required shields (PE).
