Electric fence

Dec 22, 2016

Synthetic fences encompass a wide range of products. Vinyl-coated wire fence is usually based on high-tensile wire with a vinyl coating. Some forms are non-electric, others embed layers of graphite to carry a current from the wire to the outside of the coated product so that it can be electrified. It can be of any color, with white particularly common in the United States so that the fencing is visible to livestock. Most forms can be installed on either wood posts or steel t-posts.

A variant, sometimes called "vinyl rail" or "strap fencing" consists of two or more vinyl-encased wires with vinyl or other synthetic between them to create a "rail" that is anywhere from 1 to 10 centimetres (0 to 4 in) wide. Some forms may be electrified by use of a special coating on the top wire of the "rail."

Vinyl fence is installed in a manner similar to plain high-tensile fence and must be stretched tight. Strong bracing of posts at corners and in the middle of long fencelines is required. Like other wire fences, keeping vinyl fencing tightened on a regular basis is key to safety and appearance.

A mesh form of vinyl fencing without internal wires is marketed as "deer fence" and used in some locations to augment other fencing to keep out wild animals. There are also some forms of vinyl fencing that look similar to vinyl-coated wire, but do not contain an internal wire, that are marketed to livestock owners. They are marketed as particularly safe, but their strength in containing animals is under debate. These products are very new to the market.
