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.

Fence Posts
We use galvanised or mild steel posts for electric fence installations that are robust and will last for many years. Standard colours for mild steel posts are black and white. Standard fence posts come in 5,6, 8,10,12 lines.
Flat Bar
SpaceSec use brackets that are made to a high standard to maximise security and ensure long life in the field. The level of security achieved is directly affected by the choice of bracket, the number of wires forming the electrical barrier and the distance between the brackets. Our supplier offers a large range of brackets to suit most wall types and applications. They are made from steel and are finished in a high quality outdoor powder coating, or are hot-dip galvanised for coastal conditions. Our supplier can manufacture different types of designs and finishes on request.

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
Specifications
Material: Galvanised steel
Construction: Stranded

Galvanized Wire
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
Specifications
Material: 304 and 316 Grade stainless steel
Construction: Stranded

Stainless Steel Wire
Aluminium Wire
Nemtek aluminium wire has the lowest resistance allowing long fences to be powered up, reducing the number of energizers needed. The flexibility offered by the stranded aluminium 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: • Low electrical resistance allows for longer fences to be powered by an energizer
• Good corrosion resistance for most environments ( +5 km from coastline)
• Easy to work with stranded wires

Material: Aluminium alloy
Construction: Stranded

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
