When using long lengths of polywire or galvanised wire for permanent electric fencing, it is important that they should be tight and well strained. Loose wires run a high risk of blowing around in the wind and snagging on vegetation nearby, which will drain the power source and reduce the efficiency of the electric fence. Setting up a permanent electric fence should be carefully planned in advance, with straining posts positioned at equally spaced intervals along the length of the fence, particularly in corners and at points where the ground undulates. straining posts should have their bases buried deeply in the ground and be bolstered by "stell" supports to provide additional strength. Whenever your electric wire reaches a straining post, heavy duty corner insulators should be used, since they are not only strong enough to take strain, but also insulate electric wires with great efficiency. These strainer insulators are manfactured from high impact abs plastic, making them extremely strong and durable.
