Underground Electric Wiring

Underground Electrical Cabling is Better Than Overhead Lines

Lately, considerable discussion has been dedicated to the likelihood of laying underground electrical cables rather than overhead cables, to decrease visual impact. Many distribution systems operators have introduced underground cables in numerous regions.

Though installation of underground cables is more expensive as compared to overhead cables, underground cabling is still preferred especially in urban areas. There are fundamental reasons as to why electrical engineers are choosing this method of cabling. The following are some of the reasons:


High Voltage Lines Underground


There are dangers associated with working close to any sort of power line. However, underground cables are less dangerous to technicians and the public since they are protected, encompassed by a shield and normally buried around one to three meters inside a solid conduit. Overhead lines can be dangerous if the structures/wires tumble to the ground and/or are accidentally touched.


In general, overhead lines can need more repair, through wear and tear because they are exposed to very hot and very cold temperatures. They are though, much easier to repair as their access is easy. Since underground cables are buried safely, there is a less chance of them being damaged and they last much longer.

Overhead Power Lines

Right- of- Way

If an underground link is laid underneath an urban road then the right-of-way would be the road itself thus saving space. If the underground cable is not laid besides the roadway, the right-of-way would be taking into account the measure of space required for installment and repair activities to be safely carried out. Ordinarily around 10 to 15 meters in width is required. An easement agreement would be required to guarantee vehicle access and prevent changes in surface grade or the erection of additional structures.

Home Electrical Backup Systems

Suitable Electrical Backup Systems for Home Security

Back Up Power SupplyFeeling safe and secure in your home is priceless. Installation of comprehensive surveillance and alarm systems is a step in the right direction. However, these systems should be supplied with electricity 24 hours a day, for 365 days (all year round). Power shortages and blackouts can sometimes be a common occurrence. Thus, to be on the safe side, it is best to install electrical backup systems that will provide power to the security system in your home, in case of power failure.

The following are some suitable electrical backup systems for your home security.


Installing a generator as a home backup system will guarantee protection of your home. Today, some generators run on liquid propane (LP) fuel. They are easy to install and are mounted outside just like an air conditioning unit.

A backup generator is designed in such a way that when the power is out, it starts on its own. This means that you don’t have to go online in order to start it up. They have fast response speeds so ensuring that your home security system is supplied with constant power. A generator set works well with a UPS.

Uninterruptible Power Supply System (UPS).

A UPS is an electrical appliance which supplies clean power to the load (your home security systems). It ensures that the security systems are online even when there is power failure. A UPS has an inverter or charger that charges batteries when the utility power is present.

When there is a blackout, the UPS supplies power to the security systems. The time required during the transfer of the load is minimal; it is usually in the range of microseconds. This means that your security systems will ensure security constantly without being interrupted. For this system to work well, you will need to use a backup generator to supply power especially if the utility power fails for several hours or days.

Automatic Voltage Regulators are also used to regulate voltage levels if the utility power or power from generators keeps surging. Clean and stable power should be supplied to your security systems to ensure that they operate at their optimal power ratings. AVRs protects the systems so increasing their durability.

In conclusion to be secure, your home, all your video surveillance, alarm systems and other wireless security systems should be operational all the time irrespective of whether the power is out or not. If you install these systems in your home, it means that you may also enjoy other privileges apart from ensuring your home security.
