Pet & Farm Electric Fencing

Electric Fence Nemtek has a range of electric fencing products that to keep residential pets and rurual livestocks in safe boundary. These include agricultural series electric farm fencing systems and the Petstop fence kit.

Agricultural Electric Farm Fences The new Nemtek farm specific range of Agri series electric fencing energizers are specifically designed to meet the needs of the Australian farming condition. Durability, reliability, effectiveness and value for money are paramount in every product that bears the Nemtek name. Traditionally electric fence energizers for animal farming control did not have a fence monitor to detect a break in the fence. The detecting feature has become an integral part of game and animal control. It allows the user to monitor the condition of the electric fence at the energizer without having to patrol the fence regularly, thus saving time and money.

Pet Electric Dog Fencing The electric dog fence is designed with dogs in mind, they are purpose built and powered to suit both pet and working dogs. The Nemtek Pet Stop Solar Powered Electric Dog Fencing kit is used to contain your dogs and cats in your property as well as keeps away from unwanted areas such as, flower beds, vegetable gardens etc. The Max range of the Pet Stop kit is 60 metres in boundary line.

Max Fence Length – The length of electric fence wire/tape that can be powered by energizers are a guideline only and apply to optimal/ideal fence conditions. There are lots of factors that will affect the performance of the max boundary length and power output in the max boundary length. Following are list of factors that will influence the distance that energizer can be powered:

Resistance of the fence wire – higher resistant wire means harder to transfer electric current which means shorter electric fence line and less power of output along the wire.

Type of fence wire – material of the wire will affect the electric current transfer: metal wire, poly wire (construct poly tape and metal wire) and poly tape.

Installation of the fence – how to install the fence: how many electric fence line in one boundary, what is distance between each ground rods, condition of the soil ground etc.

Proximity of the live fence wire to other earth wires – how close the electric wires to the earth wires

Amount of vegetation touching the fence – how many livestocks and pets in the boundary

Earthing of the fence system – a good earthing setup will provide a better electric circle for the fence system

Typical electric fence for small property with good earthing (no ground wire)

If the earthing conditions are good all year round, then a few electric fence level wires are enough. The good condition earthing means getting rains very often in the area, the soil moisture level is good.

Typical electric fence for small property with inadequate earthing (with ground wire)

If the earthing is not good due to poor soil condition or seasonal changes in solid moisture levels, you will require additional earthing wire to install into the electric fence circle. This makes the electric current runs along the ground wire instead from the ground.

Typical electric fence for large property with inadequate earthing (with ground wire and extra ground rods)

A ground rod need to be installed at least 100 metres away from the energizer ground rod and extra ground rods need to be added at least 100 metres way from each other. This will make sure the electric current runs pass in a shorter circuit. The strength of the output voltage can stays better even in longer distance.

Choosing Different Type of Electric Fence Wires

	Recommended Max (wire) Length (2)	Voltage at Max Length (3)	Resistance (4)	Metres per Pack
Ecostop SS3	200M	1340	13300 Ω/km	200M
Vario SS6	500M	1700	4000 Ω/km	400M
Blue Mix3	2000M	4830	380 Ω/km	200M and 400M
Blue Mix6	5000M	2930	190 Ω/km	400M

Recommended Max Length

The Recommended Max Length is base on ideal situation, such as combine with energizer that have enough output to power up the max distance, installing the system in good soil ground, installing properly with enough ground wire and ground rods. The Max length is also based on the energizer is powering one single wire in straight line only, not by multiple wires in different lines.

Voltage at Max Length

The voltage output measured from the end of the max length of the wire.

	Voltage at Start of Fence	Voltage at 200m	Voltage at 500m	Voltage at 2000m	Voltage at 5000m
Ecostop SS3	8500	1340	590	300	60
Vario SS6	8500	3260	1700	940	200
Blue Mix3	8500	7370	6150	4830	1770
Blue Mix6	8500	7900	7140	6150	2930

Examples of livestock and voltages output table

	Suitable Voltage output range
Cows	8500 – 6000
Horses	8500 – 6000
Sheep & Goats	8500 – 4000
Pigs	6000 – 4000
Dogs	6000 – 1000 (depending on the dog breeds and size)

Electric Fence Polywire (wires) Resistance

The resistance of an electrical conductor (electric fence wire) is a measure of the difficulty to pass an electric current through that conductor. The higher of resistance means harder to pass an electric current. The resistance rate is made for different purpose. The higher resistance wire will suits smaller pets and livestock as it has less voltage output. The lower resistance suits bigger property as it needs to make sure the electric current can travel a longer distance.
