SLIDING GATES AND ITS ADVANTAGES
According to our experience as technicians on site 24 hours a day, the sliding gates are slowly replacing the swing gates in most industrial and business premises. This is due to space and operational credibility. With a swing gate installed, it usually needs a lot of space to operate. .
Remember with a sliding gate, it is also ideal to have gate automation, for security and convenience reasons. In South Africa most properties will have a sliding gate in place as a means of access control. This entitles you to stop intruders. The sliding gates are made of a welded steel structure as per requirement and may be operated by an electro-mechanical or hydraulic motor, with facility of manual override. Sliding Garage doors come in different materials, such as wood, steel, and aluminum garage doors. A sliding gate is very convenient at a point whereby a number of vehicles can fit in and out at the same time during motion. A great advantage in using a sliding gate is the fact that when the road surface is inclined upwards, towards the inner or outer side, the sliding gate will open only outwards. They are also cantilevered, meaning the use of rails is minimized and helps cover uneven surfaces.
Sliding gates have a sensor control system and the dangers of you or your vehicle being harmed is safe. They are also safer to use and maintain. It is also difficult to operate a sliding gate manually unlike the swing gate. In other words you cant open it manually easier than a swing.

Installing an Electric Fence
In this article I will explain what an electric fence is before I can explain on how to install one. An electric fence system consists of a device called a power energizer, a length of bare wire and a rod used to lead the electricity into the ground. Any other enclosure involved, such as a chain link fence or razor wire, would be more accurately described as an electric fence. The power energizer may draw its power from a standard 110v or 220v outlet, but the actual amperage is often commuted down considerably. Every second or so, a pulse of high electrical energy wired down from the energizer to the ground rod.
First things first, find weather –resistant place for the controller of electric fence. In most times, most people install this in a garage or entrance of the place like a guard house or basement. Whatever your decision will be, it should be 120 volt polarized outlet available to installation. REMEMBER JUST INSTALL THE ELECTRIC FENCE, BUT DO NOT PLUG IT IN YET. Avoid installing your electric fence grounding system within 50 feet of any utility grounds, underground telephone lines or water pipes. When it comes to the grounding rode, you will need it to be 20 feet for the electric fence controller. The grounding rod should be at least six feet long (all of it underground) and made from copper or galvanized ground rod. Run a grounding wire (10 to 14 Gauge, 600V to 20,000V) from the controller to the grounding rod and use the grounding clamp to secure the wire to the rod. Ensure that the clamp bites through both the wire and the rod. To my experience, I would install more than two grounding rods which should be apart about 10 feet or so. This entaily depends on big is the land you covering. Make them flexible in order not to cause the connections to break. This should be six feet downwards. To be more precise and exact, read warning signs in manual. Should it be a time of rain and lightning, do not go near your fence. Wait till the weather settles.
We have now installed the posts, and it is time for the wiring to be installed. Make sure to use proper splices and tight connections throughout. Wrap your connections with insulation wrap to help reduce corrosion. Remember to bear in mind that the height for horses is 48 inches, which is normal size height as other animals. Also make sure you run wires closer together, close to the bottom of the fence to also stop smaller intruders from entering your premises.
With the fence posts installed, it is time to install the wiring. Start your wiring with the farthest post from the electric fence controller.
The wires from the middle to the top of the fence should be spaced about 10 inches apart. When the wires have been installed, make the connection from the electric fence controller to the top wire of the electric fence. Remember your power should be off, as stated before. Only apply when electric fence controller’s plug into the available polarized outlet. Now you can go and plug your fence on. In general, an electric fence should only be supplied with enough power to be effective, not lethal. This should be shocking purposes, to keep intruders away. The effect of most electric fence encounters is a sharp electrical shock, much like the stinging sensation of a snapped rubber band. Animals who brush up against a charged electric fence should get the idea to recoil, inflict pain not kill.
When you see a light on the controller, it’s a sign that the fence is working properly. You will need an electrical fence voltmeter to check the voltage of your electrical fence and if it working throughout the whole fence. Educate your family and staff on how to disconnect fence in case of an emergency.
