Many people may know the high voltage cable and low frequency wire by the uses like power transmission and heavy industrial applications. But electric barbed wire and fence are also some other applications of this HV cable. Cables are available in seven different voltage categories. They are - Rated, Nominal, Ultra Low, Low, Medium, High and Ultra High. The cable works at the voltage level. Their choice depends on the voltage that will be carried through the electrical wire . In this article, we will see some basic differences between the two widely used cables - HV (high voltage) and LV (low voltage).
Both cables use copper and aluminum as conductor alloys. High voltage cable High voltage cables are used for the transmission of very high voltages; usually in power plants and transformers. It will vary from 33kV to 220kV. They mostly work online. The reason for using this type of cable is that they increase efficiency in a very nice way. Since very high voltages are involved, the insulation must also be very strong in such high-voltage lines. They have a very high insulating protective layer for a reliable transmission condition. Due to the high level of electrical engineering used to transmit such high voltages, very large-scale industrial automation technologies such as DCS, SCADA and other centralized control modes are used to transmit properly through these cables and to protect human life or nearby environment without risk.
Low voltage cable Low-voltage cables are used for household and minor industrial use. It will vary from 70V to 600V. A lot of automation technology and the factories that use it use these cables because they are good enough for the work of the machine. It can be said that if high voltage cables are used for power purposes, then low voltage cables are used for control purposes. In any case, no one should touch these live wires or death may result. The power plant voltage is stepped down through transformers and substations and then normal and reliable voltage is provided for our domestic and industrial purposes. To pass all these voltage levels effectively, cables play a very important role, each cable has its own electrical characteristics that must be properly understood before selection.
High voltage wire for electric fence
There are several different types of portable electric fence 4wire cable , tape, and braid - often called "conductors" which are categorized as high voltage wires. Knowing which one to choose can be a bit tricky - especially for those new to electronic fencing. Here we will introduce you to the different types of managers to help you make the right choice for your farm: Poly-wire The most common portable/temporary fence "conductor" is Poly Wire. Poly Wire is made of plastic wires with embedded thin metal wires to conduct electrical current from the Fence Energizer. Individual strands of plastic and wire are usually tightly twisted together to form a single strand. Poly Wire lacks the strength of wire fencing, but does not rust and is easier for animals to see. Wires smaller than 3 mm in diameter are suitable for cattle, sheep, goats and pigs, while the larger 5 mm version is suitable for horses due to better visibility. Because it is available in roll form, it provides a practical option for temporary fencing solutions such as strip grazing, and it also provides a cost-effective option for subdivided pastures. poly tape Poly Tape binds a single strand of plastic and wire together to create a highly visible band. The tape is strong enough to withstand all weather conditions and will not rust. White tape is more visible against green vegetation or brown landscapes, while brown or green tape is more visible against snowy backgrounds. Electrical tape is available in different widths, each more suitable for different applications. 
Due to its improved visibility and superior strength, thicker tape is recommended for perimeter fencing, but is not the best solution in areas that experience high winds - in these cases, Poly Braid would be a better choice for perimeter fencing. Thinner tapes are more suitable if exposed to windy areas, as their thinner widths offer less resistance to wind and are therefore less susceptible to wind damage. Poly braid Compared to Poly Wire, Poly Braid has superior construction and is less susceptible to wind and ice damage than Poly Tape. Poly Braid is made up of single strands of plastic and wire braided together to form a tight weave, making it more durable and less prone to tangling and overstretching. Poly Braid is available in different diameters (thicknesses). High tensile High-strength steel wire is suitable for permanent fencing of large areas. However, since barbed wire is not like polyethylene tape or polyethylene woven fences, high-strength barbed wire is not suitable for fast-moving animals such as horses, which can be seriously injured if they hit the wire at high speed. High tensile steel wire is available in two options: galvanized steel and aluminum. Both are strong, durable, and easy to maintain and are good options for building enclosures to accommodate slow-moving animals. Galvanized steel offers an economical solution to efficiently transport electrical charges over long distances. 
Aluminum has excellent electrical conductivity - four times that of galvanized steel, but it tends to be more expensive than steel wire. Turbo line Turbo products use the same best electrical wire , tape and braid construction as previously described for Poly - with one big difference. Turbo products have 9 strands of conductive metal, including copper, making them 48 times more conductive than Poly products, which only have 6 strands of stainless steel. This means that with Turbo your voltage will stay strong and "shock" further from your fence than Poly products. Longer temporary enclosures (over 200m) should always be constructed using Turbo products to ensure maximum livestock control. horse fence If you own a horse, Equine Fence Wire is the safest and most effective electric fence for your horse. This high-tension, long-life fence uses a specially designed wire coating to reduce the risk of damage. Turbo Braid can be used as a low tension semi-permanent fence replacement for Equine Fence Wire. The braided design won't tangle or overstretch, and it's easy to install. Semi-permanent wire fencing is highly visible, easy to build and can last for years, making this type of fencing an economical and popular option for horse owners. 
High voltage cable for electric fence
One way to improve the electric fence is to use high voltage cable rather than the HV wire and carol electrical wire . Connecting the network to a normal 12 volt battery alone will not provide enough energy to power the fence and will not function properly. 12 volts must be boosted to 5-6000 volts with a voltage device. Also plugging it directly into a 220 volt outlet would create a very dangerous system as it would charge at 13 amps which is very dangerous. A normal voltage apparatus operates at 15 - 500 mA. How does the web become secure? How does the electronic fence work? Whether it is a network system or a standard stock fence, the principle is the same. The electric fence consists of an open circuit consisting of two arms. 1/. The first arm is a fence that connects to the power terminals on the fence assembly. This part must be completely isolated from any other conductive material (soil, leaves, grass, trees, metal or brick) with plastic insulators or an air gap of at least 3 cm. It does not need to loop on itself and can be a single line away from the exciter. 2/. The other arm is the ground itself, connected to the ground terminal of the exciter via a ground pole/post. This then leaves an open circuit (as shown) waiting for the wrong animal to close it. 
When the animal (as shown) touches the hedge and the ground at the same time, the circuit is closed. This allows current (electrons) to flow through the target animal down through the fence to the ground and back to the stimulator through the ground stake where the animal receives a shock when it touches the wire. When an animal touches a wire, it causes the animal's muscles to contract, similar to what human muscle spasms feel like. When you use the mains, the current is supplied continuously, which makes the gripping effect very dangerous because the victim cannot release the power source. With the pulse of the electric fence, this spasm is temporary and the victim is able to withdraw from the energy source. The animal will associate this unpleasant feeling with touching the fence and will prevent it from being touched again in the future. The fence is thus not intended to harm the animal physically, but rather as a learning tool to prevent it from happening again. The voltage sent through the charlotte wire is high, but the current or gain (amps) is very low. As long as the current or amperage is the same, a 220 volt shock does as much damage as a 10,000 volt shock. Electric fence generators emit high voltage (about 8,000 volts) but very low current (about 120 mA). It shouldn't even kill a squirrel. This output is ensured in two ways, first by releasing the flow of electrons from the capacitor in regular pulses of high voltage but very low current. 
The amperometric component of the charge is greatly reduced to numbers in the range of 15 - 500 mA. (Most devices operate in the 100-150 mA range)*. The power supply is 13-15 amps. Second, the electrical energy pulses through the wires. This means that once a second, for 1/300 of a second, it sends an electrical impulse to the wire. The reason for the pulsating current is that anything that comes into contact has a chance of removing itself if it touches a wire and gets an electric shock. If the current is not pulsating (like most appliances - hair dryers, radios, toasters, etc.), anything that comes into contact with it will continue to receive a shock and the muscles will respond to the "grabbing effect" of the electrical impulses until the current stops. Disconnect or something will pry them up. Compare this with the other two cases. 1/ Static electricity generated by touching the door, about 30000 volts, 1/1000 at 5 mA. For a second, uncomfortable, but not lasting. 2/. Main network. 220 volts, 13 amps, constant, unpleasant, often causes death. The electronic fence has a weak current and pulsating current and is a safety product. It is the strength of the current in the charge and the constant connection that makes electricity dangerous.
