SpaceSec is a specialised company that concentrates its business on commercial and domestic installations.
We installsingle or multizone electric fence systems with battery backup. Our preferred energisers supplied by Nemtek can be linked to your alarm systems and they can have their own siren’s connected.
We install and maintain electric fence systems for homes, offices, estates, commercial and business parks. All our electric fences are installed in compliance with the law.
Electric fence is your first line of defence and proves to be an excellent deterrent because of its high voltage and shocking capabilities.
If an electrIc fence is installed correctly, it will be an asset to your security and can alert you when a line is cut or if someone shorts the wires when jumping over.
Electric fencing is installed with aluminium, galvanised or stainless wire. Poles are installed every 3m and a typical 6-line fence will increase the height of your fence by about 0,5m. Warning signs are installed every 3m and on all gates.
Parts Of An Electric Fence
When an electric fence is installed in series, the energiser monitors the return voltage. When a line is cut, there is no return voltage and the fence immediately alarms.
Below are some standard parts that are used when installing an electric fence
1 - Fence energiser
2 - Fence posts
3 - Fence wire
4 - Insulators
5 - Earth Spikes
6 - Stays
7 - Ferules
8 - Fence warning signs
9 – Tensioners
10 – Springs and hooks
We use quality materials to build robust electric fence solutions and install them in a series circuit for best results.
Energisers
For our electric fence energizers we chose Nemtek as our preferred supplier because they are a South African energiser manufacturer and they understand the South African consumers security needs. Nemtek supplies a wide range of energisers for every application. Their energiser and brand have proven to be very popular with South African consumers.
Energizers For Home Electric Fences
Merlin 4i
The model Merlin 4i, comes with a control keypad that provides the ability to remotely control and program the energizer. Up to four keypads (EE-MKP) can remotely control the energizer which can be placed near the fence. It is a convinient solution in the case distance is a problem.
Wizord 4
Wizord-4i
The Wizord 4i energizer makes life easier as all Wizord models. Easy installation and maintainance, tested durability make this energizer a very reliable solution for both home and commercial security.
Energizers For Commercial & Industrial Security
Druid-18LCD
The Druid 18LCD Energiser comes with the Adaptive Power Technology (APT) pioneered by Nemtek, and it detects the power a fence can handle and so it makes a more adjusted operation of the voltage, avoiding to spend energy that is not needed and also avoiding false alarms. The LCD display makes reading comfortable and provides a complete control of the status of the fence.
Druid 25LCD
The Druid 25LCD model comes with the Adaptive Power Technology (APT) provided by Nemtek, and is an ideal energizer for any purpose. Detects the power a fence needs to perform better, and so it uses the right voltage avoiding false alarms and wasted energy. Traditional network cables or Druid`s own synchronization modules (which use orbiting satellites) can be used to synchronize energizers. Easy control of the status of the energizer with the LCD display, make this energizer a robust and reliable solution for any purpose.

Wire
We use 3 types of wire namely galvanised, aluminium and stainless steel.
Wire type and dimension is determined by distance and the electric fence energizer. Galvanised and aluminium wire have lower resistance than stainless steel.
Galvanized Wire
Stranded galvanised steel is high tensile and hard to cut. The flexibility offered by the stranded wire construction makes working with this wire easier during installation and results in a neat clean look on the fence without compromising the fences performance.
Features:
• Easy to work with stranded wires
• Ideal choice for in-land use where corrosion is low
• High in tensile strength which us harder to cut

Stainless Steel Wire
Stranded stainless steel offers a higher resistance to corrosion environments and a longer life span on the fence. The 316 grade is the wire of choice for highly corrosive coastal areas.The flexibility offered by the stranded wire construction makes working with this wire easier during installation and results in a neat clean look on the fence without compromising the fences performance. Features:
• Easy to work with stranded wires
• Stainless steel grade 304 can be used in most corrosive environments and near the coast (5km)
• Stainless steel grade 316 can be used in most harsh corrosive environments and on the coast .
• High in tensile strength which us harder to cut

Insulators
Most electric fence posts or poles come with an insulator that’s been designed to work on that post. Some insulators are interchangeable, and others are fixed and will only work on the post it was designed for. Electric fence insulators are designed to insulate against voltages in excess of 10 000V
The flat bar insulator is used with the flat bar profile posts. The flat bar insulators have the following features:
• quick fit clips on the top and bottom for faster installation
• feed through clip option built in
• easy to change and maintain
They are available in black, white or beige
Specifications
-UV stabilised for external use.
-Virgin materials are used in their manufacture which are designed for a long life.

Electric Fence Earthing
Earthing is an integral part of an electric fence. A bad earth will cause a low shocking voltage which will render the electric fence useless. Correct earthing procedure is to have 3 earth spikes as close to the energiser as possible and 1 every 50m after that.
Copper Cladded Earth Spike
The copper cladded earth spike or stake is used to earth the electric fence system. A minimum of 3 earth spikes must be knock into the ground near the electric fence at a minimum of 1.5 m apart. Connect these earth spikes to the energizer or the fence using the high tension insulated cable (HT). In areas where earthing conditions are bad you may be required to add a few more earth spikes/stakes along the fence line and connect these back to the energiser.
Features:
• Copper clad nuts and washers
• Available in both 1.0m and 1.2m lengths
• The double nut and washer allow for a good electrical connection with the HT cables
Specifications
Finish: Copper claded
Lengths: 10mm x 1.0m

HT (High Tension) Cable
The A-series high voltage electric fencing insulated cable is used as a lead out cable from your energizer to the fence and for all other insulated high voltage transmissions. It is used with a range of aluminium alloy wires and galvanised earth spikes.
Features:
• Ideal cable when aluminium wire is used
• Low electrical resistance reducing power and voltage drops over large distances
