High voltage security fence

High voltage security fences are perimeter security barriers that use electricity to enhance security. They typically consist of strong, often metallic, fence panels or wires spaced closely together, equipped with electrical energizers. These energizers deliver a high voltage, low current shock to anything or anyone that comes into contact with the fence. This shock is designed to be non-lethal but startling enough to deter intruders. Such fences are commonly used in high-risk areas like military bases, power plants, and commercial farms, as well as in residential properties requiring advanced security measures. They deter unauthorized entry through their physical presence and create an additional psychological barrier and a painful electric jolt to intruders.

High-voltage security fences are designed to protect critical infrastructures and sensitive areas from unauthorized access and potential threats. These fences are typically used in locations that require a high level of security due to the potential risks associated with breaches, such as military bases, prisons, airports, power plants, and border control areas.

Types of high-voltage security fences

High voltage security fences can be classified into different categories based on various criteria to meet diverse security needs and operational requirements.

• Based on construction material

  There are three main types of materials used in constructing high-voltage security fences. The first type of material is wire rope. Wire ropes are known for their exceptional tensile strength, making them suitable for creating durable and robust fencing systems. Another type of material used in these fences is steel. Steel is a versatile material that can be used in various forms, such as welded mesh panels or chain-link designs. Steel fences offer excellent corrosion resistance when galvanized or coated in protective materials. The third type of material used in high-voltage security fences is aluminum. Aluminum fences are lightweight and resistant to rust, making them ideal for locations with high humidity or coastal environments.

• Based on voltage level

  High-voltage security fences can be categorized into different voltage levels based on the amount of voltage they produce. Low-voltage systems typically operate at around 2,000 volts. These systems provide a mild shock that is enough to deter intruders without causing serious injury. Mid-voltage systems deliver a shock of about 5,000 volts, which is more effective in deterring potential security breaches. On the other hand, the high-voltage systems produce a shock of 10,000 volts or more. These are designed for critical applications where maximum deterrence is required.

• Based on energizing method

  High-voltage security fences can be categorized based on how they are energized or the type of electrical system used to power them. The first type of energizing method is the capacitor discharge system. It stores electrical energy in capacitors and releases it rapidly to produce a shock. Another common type of electrifying method is the induction coil system. This system steps up the voltage of the supply using induction coils to increase the shock delivered by the fence. The third type of electrifying method is the flywheel generator system. This system uses flywheel generators, which are mechanical devices that store energy rotationally, to generate high voltages for shocking.

Design of high-voltage security fences

High-voltage electric fencing design includes a wide range of aspects that are taken into consideration to ensure the fence's overall efficiency and safety. These aspects range from the types of materials that are used during construction to the size and voltage of the wires.

• The materials that are used to construct high-voltage electric fences are usually galvanized steel, stainless steel, or aluminum. All of these materials are known for their exceptional resistance toward corrosion, which increases the lifespan of the fence, as well as their ability to withstand harsh weather conditions. Moreover, the wires are often coated with insulators of high quality so that they may resist ultraviolet radiation and extreme temperatures.
• The design of the fence can vary in terms of its number of wires and the voltage levels that it has to offer. In order to achieve maximum security, the barriers usually have multiple wires that are placed at different heights. All of these wires carry a high voltage, which serves as a deterrent to any unauthorized personnel trying to cross the barrier. The voltage levels on the wires can also vary depending on what the fence is being used for; however, the voltages are usually kept high enough to ensure that no one dares to cross it.
• The spacing between the wires is another important aspect that is taken into consideration during the design of the fence. The spacing between the wires is kept as small as possible to ensure that no one is able to pass through the barrier even if they try to. This spacing also prevents objects from being stuck between the wires.
• The posts and supports that are installed within the high-voltage electric fences are designed using strong materials so that they can bear all of the tensions that the wires might cause. These posts are usually made out of concrete or heavy-duty metals in order to provide longevity as well as stability to the entire structure.
• High-voltage electric fences are designed such that they are easily visible to anyone who might be approaching them. This is done so that the risks of accidental contact with humans or animals are minimized. To increase visibility, the fences are often painted with bright colors or marked with warning signs.

In short, the design of high-voltage electric fences consists of a wide range of aspects that are taken into consideration to ensure the overall efficiency of the barrier. These aspects include the materials that are used to build the fence, its voltage levels, the spacing between the wires, and the visibility of the posts, among others.

Usage scenarios of high-voltage security fences

• Perimeter security

  The main purpose of high-voltage electric fencing is to provide perimeter security.
