The support rod 1 is made of resilient reinforced fiberglass rods using a dielectric binder, the lower end 31 of the rod 1 is made pointed to facilitate embedment into the ground by means of the pedal 3. Optionally, the fixing sleeve 5 can be made integral with the body 4 of the insulator 2 or pedal case 3.

The device for suspending the electric fence wires is assembled as follows.

First, the assembly of the insulators 2 and the pedals 3 are made. To do this, take the case 4 of the insulator 2, mount the fastening sleeve 5 therein, insert the base 12 of the sleeve into the opening 8 5 of the body up to the stop shoulder 15 until it triggers: latch 16.

rod 1 with its blunt end in succession pedal 3 and insulators 2. Turning clamping device 6 behind annular protrusion 19 with emphasis on additional protrusions, 27, achieve with fixing insulators 2 and pedal 3 at the required height of the support rod. The assembled device with a pedal 3 is fixed in a vertical position by dipping into the ground the pointed end 31 of the support rod 1. The electric fence wires are installed by passing the wires 24 into the insulator hole 23 through the labyrinth formed by the bracket 25, the protrusion 26 and the body body 4. The removal of wires 8 can be performed in reverse order. The reliability of the operation of the device

during the operation characterized by 25 n air chambers, made in

The strength of fixing insulators and pedals on the support rod, ease of assembly of parts on the rod before operation, ease of adjusting the height of the position of the insulators and pedals when mounting the device on a pasture, having good electrical insulation properties when applying high voltage pulses to the wires as in a dry, and rainy weather.

The electric fence of the portable type contains several tens of devices for suspending wires that are installed on pasture around its perimeter. Installation and disassembly of devices can be carried out 2-4 times per day or once every 5-6 days, depending on the adopted technology of grazing, the yield of grass, and other factors. Before the beginning of grazing behind an electric fence, animals are familiar with the effect of electric repellent shocks. In this case, animals have uncoordinated movements of the body, leading to intense mechanical effects of animals on the current-carrying wires and, accordingly, on devices for their suspension. The high strength of the fixing of the insulators on the elastic support rod ensures reliable operation of the electric fence in the mode of training animals and reduces the labor costs of servicing

go staff; and repair damage. An elastic support rod made of fiberglass-reinforced rods using a dielectric binder has the positive property of self-healing after considerable bending during the intense impact of animals on the electrical fence. In addition, the glass-plastic support rod, in comparison with metal serial domestic products, provides a significant improvement in the electrical insulating properties of the device in dry weather. In rainy weather, the surface of the support rod is accessible to drops of rain, which sharply reduces the surface electrical resistance of the insulation. To ensure good electrical insulation in rainy weather, the insulators installed in the support rod have upper and lower levels.

circular cavities inaccessible to rain. In this case, the device for suspending the wire of the electric fence enclosed by rain becomes separated from the wetted support rod by two protective legs in the form of airborne measures.
