Prison electric fence

Types of prison electric fence

Prison electric fences are designed to prevent intrusions and escapes from prisons. These electric fences are made to give a strong electric shock to anyone who tries to touch or climb over them. They are safe but highly secure barriers used in prisons. There are several types of electric fences, including the following:

• High voltage electric fence: These fences can generate voltages ranging from 5000 to 15000 volts, which can lead to severe shocks but are usually not fatal. They are often used for maximum security prisons and are typically placed on top of existing walls or fences.
• Modular electric fence: These fences are made up of different parts, allowing for flexibility and the ability to adjust the size and shape of the fence. They can be used for various prison areas, including cell blocks, yards, and perimeters.
• Insulated electric fence: These fences are built with insulation to prevent accidental shocks to prison staff and visitors. They are used in areas where there is a need to minimize the risk of unintended shocks.
• Solar-powered electric fence: These fences use solar energy to power the electric shocks. They are energy-efficient and can work independently of the main power supply, making them suitable for remote or off-grid prison locations.
• Integrated electric fence: These fences combine other security features like surveillance cameras and motion detectors. They provide a comprehensive security solution for prisons and help monitor and control access to the electric fence.
• Perimeter electric fence: These are installed around the prison's outer walls to prevent unauthorized access from outside. They are usually taller and have more voltage than other types of electric fences used inside the prison compound.
• Electrified concertina wire: Concertina wires are giant coils of barbed wire. When electrified, they add an extra layer of security to the prison perimeter.
• Electric security fence: These fences can be used for prisons and other security applications. They are versatile and can be customized to meet specific security requirements.

Design of prison electric fence

• The fence

  Prison electric fences are generally made of galvanized steel wire. The wire can come in different gauges, but it is often 9 to 14 gauge thick. The wire is weaved into a mesh pattern which creates small squares. The mesh is then attached to metal posts that are spaced at regular intervals. The posts are secured into the ground with concrete. The fence can be covered in barbed wire or razor wire at the top for added security, and these wires can be electrified as well.

• The wires

  The electric wires used in prisons are high voltage and can vary in size. Some common wire sizes include 12, 14, or 16 gauge. The wires are insulated with a durable plastic coating that can withstand weather conditions. Inside the wires, there are multiple copper strands that are tightly bundled together. This construction allows the wires to carry a high voltage charge while remaining flexible enough to install on fences.

• The insulators

  Insulators used in prison electric fencing are usually made of glass or ceramic materials. They need to be able to handle a lot of voltage without breaking. The glass or ceramic material does not conduct electricity. This means the insulator can support the wires without letting any electric current flow through where it is not supposed to. Both glass and ceramic insulators are very strong options that will last a long time outside on a prison fence. They each have qualities that keep the high voltage wires working safely for their purpose holding them up between metal posts.

• The energizer

  The energizer for a prison electric fence takes power from the wall and changes it into high voltage electricity. First, the wall power goes through a transformer to make the voltage higher. Then, a special circuit called a coil winding boosts the voltage even more. Finally, switches called transistors let the stored energy rush out all at once. This creates the high voltage shock used to power the fence wires. Energizers are designed to last a long time while safely changing wall electricity into the dangerous high voltages needed for the prison fences.

Usage scenarios of prison electric fences

The applications of electric fences in prisons are diverse and numerous. Although they are commonly found in maximum security prisons, their versatility allows them to be used in different types of correctional facilities, including minimum and medium-security prisons, juvenile detention centers, and mental health institutions. This electric security fence has a lot of uses in these places that require tight control over inmates and protection against any escapes or intrusions.

• Perimeter security

  High voltage electric fences are installed on the outer walls or gates of prisons to prevent inmates from escaping. The electric current delivered by these fences is powerful enough to deter anyone from trying to cross it.

• Intruder detection

  Electric perimeter fencing systems can sense unauthorized entry into the prison premises. If an individual touches or cuts across the fence, an alarm will go off, notifying the security personnel about a possible breach.

• Cell block security

  Within maximum-security prisons, electric fences may be used in cell blocks to further secure areas housing dangerous criminals. This provides an extra layer of protection within the facility.

• Control of riots

  During riots or large-scale disturbances, lockdown procedures may require activating additional security measures such such as deploying electric fencing around certain areas within the prison compound. This helps control movement and prevents inmates from accessing restricted zones.

• Protection of sensitive areas

  Areas like administration buildings, visitor centers, or evidence storage could also be secured using electric fences since they are sensitive locations within a correctional facility that require heightened security measures against potential attacks or breaches.

How to choose a prison electric fence

• Purpose and Requirements:

  Determining the purpose of the electric fence and its requirements is the first step to take when choosing a prison electric fence. Knowing its purpose or the requirements for the electric fence will help users narrow down the options available for them to choose from. For instance, if users need the fence for perimeter security, they should look for fences that are designed specifically for that purpose. On the other hand, if users need the fence for internal security, they should look for fences that are designed for internal security.

• Height and Design:

  Choosing the right electric fence for prisons requires users to consider the height and design of the fence. The height of the fence is very important, as it determines how secure the electric fence is. A good electric fence for prisons should be tall enough to prevent anyone from escaping. Besides, the design of the fence should also be considered. A good prison electric fence should have a design that is hard to climb or breach.

• Materials Used:

  Another factor that should be considered when choosing electric fences for prisons is the material used in making the fence. A good prison electric fence should be made with durable materials that can withstand harsh weather conditions. The materials used in making the electric fence should also be resistant to rusting and corrosion.

• Voltage and Shock Level:

  In choosing the right electric fence for prisons, the voltage and shock level of the fence should be considered. The voltage of the electric fence determines how powerful the electric shock is. A good prison electric fence should have a high voltage that delivers a painful but non-lethal shock to anyone who touches it.

• Safety Features:

  Safety features are also important considerations to make when choosing the right electric fence for prisons. A good electric fence should have features that prevent accidental shocks to others except the intended person.

• Control Systems:

  Control systems should also be considered when choosing the right electric fence for prisons. A good electric fence should have a control system that is easy to use and operate. Control systems enable users to easily monitor and manage the electric fence.

• Cost and Budget:

  Lastly, the cost of the electric fence and the budget should also be considered when choosing the right electric fence for prisons. A good electric fence should be affordable and within budget.
