Pro’s and Con’s & DO’s and DON’T’s
The previous page (CON), simply put, is and describes a sham security. Designed and installed for show and minimum maintenance, it is a major stretch to consider that any fence installation that is that easy to bypass any kind of security other than looking scary.
The following fence example (PRO) has the same amount of wire, support posts and materials as the not-so-secure fence described on the previous page, but the fence interconnections, as shown below, is actually designed for perimeter security and very difficult to bypass. This type of fence connections as shown could be a few feet long to several hundreds of feet wide/long, however it is still interconnected as shown. fence
And to make it a tad more secure, the “grounded” conductors should not be distinguishable from the high voltage conductors.
One would recommend solid wire support on each section end and additional support every 20 feet or so on the longer stretches. All each wire tension is added and is supported by the corner and end posts which are usually 4’ steel posts. The support wires are only carrying the weight of the wire, and are usually 1 to 1.14 inch fiber or composite and only support the weight of the wire.
On this illustration, the wire closest to the ground is carries high voltage. Most of the attempted intrusions will be through on the ground, either through or under your fence.
A hot bottom wire provides a much higher security level, it also requires more maintenance to keep it clean. A few will try to cut through the fence, and even fewer will attempt to go over the top with a mat of some material to keep them away fro the voltage.
The best fence configuation is to utilize a hot bottom wire and a cheap ground mat under that bottom wire solves the grass and weed problem and maintains the highest security level with your high voltage electric fence.
Literally, every electric fence that is installed in a security application uses the same single hot wire design and construction premise. High voltage is fed into one end of a single wire and which is then folded back and forth, but remaining a single loop which is verified and measured at the far end. The alternate wire are interconnected and connected to a solid ground as shown in the above illustration.
Individual fence sections can be connected to each other by a single wire, especially around a corner. Standard high voltage fence construction suggest that you don’t wrap your fence around a corner unless absolutely necessary.
The high voltage fence wires will be folded back on themselves, but always remains a “single” wire which carries the high voltage pulse. However, when the high voltage folded wires are not separated with a grounded wire, then it becomes a simple matter to bundle all the wires carrying high voltage and get them out of the way without worrying about an alarm as demonstrated on the previous page.
