Great for grandkids, retirement homes or coffee tables.
Conductivity measures the amount of electrical current a material can carry. The opposite measure is known as resistance.
Many of Premier’s nets feature a green and white superconductor that has both stainless steel and tinned copper filaments for optimal conductivity. These “premium” nets are 10 times more conductive (38 ohms per 1000') than our “basic” nets. This enables the electric pulse to travel much farther and be less affected by weed contact.
We do not recommended the basic nets listed below for fences exceeding 500 ft in length:
Customers who are unhappy with netting are often those who’ve chosen one of these or their farmstore equivalents. Why do we offer them? Because they are similar in design and conductivity (380 ohms) to nets from our competitors—and comparisons make decisions easier.
Line posts are built into the net. Three options are available.*
Tip: To insert a line post into frozen or hard soil, use a power tool to drill pilot holes.
* Not all fences have all line post options.
Conventional electrified fence systems rely on soil moisture to be effective. However, not all areas have the required moisture.
Dry soil increases resistance—a weaker, less effective pulse occurs that does not deter animals.
To overcome this, Pos/Neg nets* are wired to allow the use of every other horizontal strand as an extension of the ground terminal. Because half the strands are connected to the ground terminal or ground rod, reliance on soil moisture is reduced. A PowerLink must be purchased separately to make the secondary ground connection.
In order to receive a shock, the animal must touch both a positive (hot) and negative (grounded) strand at the same time. This will deliver more pain to the animal than an all hot net (Pos/Pos) because moisture in the soil is not required to complete the circuit.
Pos/Neg fences can be converted to Pos/Pos in moist conditions. Remember, all fences must be kept free of vegetation.
* Not all fences have Pos/Neg options.
“Plus” nets—6'8" spacings between built-in line posts*
Standard nets—10' or 12' spacings between built-in line posts*
* Spacings are approximate.
Distance between built-in line posts may vary by product.
Dan Morrical joined the Iowa State University staff in 1984 as Extension Sheep Specialist after completing his doctorate degree at New Mexico State University. He held the rank of Full Professor as of July 1, 1995 and retired from full-time teaching in 2017.
While at Iowa State University, Dr. Dan Morrical was responsible for educational programs in all areas of sheep production, ranging from nutrition, genetics, marketing and management. Research areas focused on applied projects in the areas of nutrition, forage utilization, genetics, out-of-season breeding and lamb survival.
Dr. Morrical has been heavily involved in providing educational resources to the sheep industry. He has authored over 30 extension fact sheets, ration balancing software programs, grazing videos and co-authored the nutrition chapter of the SID Handbook with Dr. Margaret Benson from Washington State University.
Dr. Morrical now serves as Premier’s on-staff small ruminant nutritionist and sheep production advisor. Most recently, he’s introduced a line of “GOLD FORMULA” mineral premixes under The Shepherd’s Choice® brand, aimed to maximize hoof health and immunity.
Braiding instead of twisting the horizontals increases the frequency of metal filaments on the outside of the strand.
