Abstract: An electrode arrangement for capacitive guard fences wherein the conductor is horizontally stretched substantially parallel to the ground has a shape for preventing formation of water droplets which may collect as a result of precipitation from generating a false alarm and which also deters small animals from perching on the electrode. In one embodiment the electrode has a rectangular cross-section with the longest sides of the electrode being disposed substantially vertically. In another embodiment the electrode consists of two conductors having circular cross-sections which may be disposed parallel to one another or twisted. A further electrode embodiment has at least three conductors having very small circular cross-sections disposed at equal intervals from one another around a circular circumference. Means for facilitating water droplet runoff are provided at equal intervals which simultaneously serve as spacers for the conductors.

Abstract: An insulator arrangement which may be employed, for example, on a capacitive protective fence comprises three principal elements:(1) an insulator, made of ceramic or plastic, having at least one ring-shaped recess arranged on its bottom to form a long path for leakage current;(2) a mounting bracket extending axially downward from the bottom of the insulator which has fastening means on its free end for securing an electric wire; and(3) a metal cup mounted over the insulator to protect it from the environment. A mounting element consisting of two arms forming a U-shaped configuration is arranged on the metal cup to facilitate mounting on a fence post.
