What is a Low Voltage Electrical System?
A Low Voltage Electrical System (also known as Extra Low Voltage System – ELV) is a system that operates at low voltage. It typically includes sub-systems such as CCTV surveillance, telephone lines, television networks, fire alarm systems, and more.
While the overall investment in this system is relatively small, it brings significant value and benefits to both end-users and investors.
In general, a construction project consists of two major components: infrastructure construction and mechanical & electrical (M&E) system installation. The low voltage system plays a crucial role as a key component within the M&E portion of the project.

Why is the Low Voltage (ELV) System Important?
The Low Voltage System (ELV) includes essential devices and applications that ensure communication and security for the entire building or facility. This system is designed to support people in their daily lives and work environments, enhancing both comfort and safety.
Moreover, the ELV system reflects the modernity and class of a project. That’s why today, end-users, investors, and M&E contractors all place significant emphasis on implementing ELV systems in their projects.
