Our society has grown accustomed to digital devices and communication equipment. This has led to high demand for low voltage cables in residential, commercial, and industrial areas.
As a result, low voltage power cables have become an integral part of our daily lives. If you want to learn more about them read this article.
What are they?
Low voltage electrical equipment relies on a separate current from what is provided by power outlets, fixtures, and switches. This type of equipment requires the use of low voltage (LV) cables, which form their own network.
This network enables low voltage equipment to work properly and reliably for digital and communication purposes. Because LV cables do not pose as great a risk as other types of wires, LV equipment does not need to be as closely inspected.
As already mentioned, a network comprised of LV cables isn’t identical to standard electrical wiring. Low voltage wiring systems are specifically designed for:
- Network data;
- HD video;
- Audio systems,
Installing LV cables typically happens during or after the installation process of basic electrical.
The low voltage range can reach as high as 1,000V and anything lower than 70V is considered extra-low voltage. The most common low voltage numbers you will see are:
There are two different types of low voltage cables:
- Alternating currents (AC),
- Direct currents (DC).
Let’s take a closer look at the differences between AC and DC.
Alternating current (AC)
This type of current is characterized by its periodic change of direction in the wire, which causes the current to reverse its course. AC is used in homes and businesses and is considered a safe option for electricity needs.
Direct current (DC)
This type of current takes electricity on a direct course from its source to its destination, which is the item in need of power. DC is most often used for batteries. It’s best to use DC for smaller projects because of the significant decrease in energy over the course of longer distances.
Cable structure and materials
LV cables can have either an adjustable or firm structure and are circular, compacted, or configured into a specific shape.
Low voltage conductors are made of the following elements:
- Plain or tinned copper,
- Solid or stranded aluminum.
Low voltage cables use the following insulating and shielding compounds:
- Elastomer compounds.
These shields are necessary for guarding the cable against interferences as well as trapping electromagnetic interference (EMI) in the cable, preventing the leakage of energy and radiation.
LV cables can be designed as either single-core or multi-core cables, and the core is made of aluminum, copper or metal.
The layer below the outer sheath is comprised of steel or aluminum. This layer’s purpose is to offer mechanical protection.
How are they used?
LV wiring is the appropriate choice for many different kinds of projects. If you want a broad view of its applications, check out the following list of the various ways LV cables are used:
- Sound and security;
- Video surveillance,
- Fire alarm.
But if you want some specific examples of how LV cables are used in everyday life, you are in luck. We are going to give you some examples right now.
Although many houses no longer have home phones, most businesses still rely on telephone outlets for their operations.
Who doesn’t need Wi-Fi? These networks require LV wiring to operate.
Many businesses are using low voltage cables for their video and audio equipment. This is because LV cables perform well and are cost-effective to install.
But the installation process should not begin until the location of the business’s audio and visual equipment has been decided.
Security and surveillance
Many homeowners and business owners feel more secure after installing a security system. Low voltage wiring can be used for this project. The wiring is installed wherever video cameras, sensors, and alarms will be needed.
Sensors are often situated at the windows, doors, and outside of the building. After the wiring has been put into place, the alarm company can finish off the job by implementing their system into the home or business building.
This communication system allows for quick and easy audio and video transmission. It is yet another example of a project that can be completed with low voltage wires.
Low voltage lighting cables can be used to light up the backyard and highlight certain landscaping elements, such as pathways, trees, plants, and more.
Other housing needs
In addition to the examples we have already provided, there are many other ways that LV cables can be utilized by homeowners. Some examples include:
- Garage doors;
- Outdoor lighting,
- Household batteries.
