A wolf-resistant fence, that sounds impressive. But actually it’s just five electrical wires. However, there are strict requirements for those who want to install such a grid. Anyone who does not comply with this cannot receive compensation after a wolf attack.
For example, it must consist of at least five power wires with at least 4,500 volts. The lower wire should hang no more than 20 centimeters above the ground, the upper one should not be lower than 1.20 meters. That way a wolf can’t go under or over it.
