Low and medium voltage electrical installations for residential projects.

Planning, Regulations and Recommendations:

Inform yourself about the local and national rules and regulations applicable to the installation of low and medium voltage electrical installations. These may include safety standards, wiring requirements, protection against short circuits and current leaks, protection against surges, and more.

Before starting any work, it is important to plan and design the electrical system. Identify the specific needs of the site, including the number of outlets, lighting points, special outlets (for specific appliances or equipment) and any other special requirements. This will help you determine the location and distribution of electrical circuits.


Temporary Power Supply: If the project does not yet have power, make sure there is a temporary power source to power the tools and equipment needed for installation. This can be done by means of a portable generator or a temporary switchboard.

Markings and signage: Identify cable routes by appropriate markings. Use appropriate signaling and labeling methods to indicate routes, sockets, panels or any other relevant elements of electrical installations.


To protect electrical installations against dust and moisture, it is important to consider some safety measures and appropriate protection methods:

-Watertight junction boxes

- Gaskets

- Sealed cables and conductors

- Sealed plugs and sockets

- Adequate ventilation

Regular maintenance: Carry out periodic maintenance to check the integrity and functionality of electrical installations. Replace any damaged or worn components and fix any identified safety issues.

Restoration and modernization of existing electrical installations.

Refurbishment and modernization of existing electrical installations are important processes for ensuring the safety and energy efficiency of a building.

We check for malfunctions, damaged cables, outdated sockets and switches or other problems. Next, we create a detailed plan for the modernization of the electrical installation, setting goals and budget.

To modernize and optimize the electrical installation, you can add automation and control systems. For example, you can install motion sensors for automatic lighting in rooms or an intelligent temperature control system to save energy.

Site preparation for the installation of electrical installations.
We ensure that the installation site for electrical installations is properly prepared, taking into account all safety requirements. 

Before starting the actual site preparation, it is important to have a detailed plan of the electrical installations. This plan must include the location and routes of cables, power points and necessary equipment.

Aerial electrical connections.

Overhead electrical outlets are types of connections used in the distribution of electricity to buildings and homes. These consist of overhead cables that run from the mains electricity grid to the building or home in question.

Overhead power lines usually consist of distribution cables suspended from poles. These poles can be placed along streets or in the courtyards of buildings. Distribution cables are usually insulated and securely suspended from poles by means of insulators.

To ensure safety and prevent accidents, overhead distribution cables are usually placed at a height sufficient to avoid accidental contact with vehicles or people. Insulators used on poles help prevent short circuits and other problems caused by weather conditions or other external factors.


An alternative to overhead electrical connections is underground electrical connections. These involve placing distribution cables in an underground system, eliminating the visual appearance of suspended cables and reducing the risk of interference from weather or other external factors.

We offer professional electrical wiring services, ensuring that they are installed correctly and in complete safety. These branches are essential for a supply electricity to buildings and properties.

Single-phase and three-phase installations.

These categories refer to how electricity is distributed in that system.

a. Single-phase installations:

A single-phase installation is an electrical installation that uses only one phase of alternating current. In this case, the electrical voltage varies between two points, from a maximum value to a minimum value and then back to the maximum value in a complete cycle. Single-phase installations are generally used for small, residential or commercial premises that require less electrical power. Examples of appliances and equipment that operate on single-phase installations include small appliances, light bulbs, sockets and ordinary wall sockets.

b.Three-phase installations:

A three-phase installation is an electrical installation that uses three phases of alternating current, out of phase with each other at an angle of 120 degrees. Each phase supplies an alternating voltage, and the combination of the three phases allows the supply of higher power and larger loads. Three-phase installations are generally used in industries, large commercial buildings, power plants and other applications that require large electrical power. Three-phase motors, welding equipment and other industrial machinery are examples of devices that require three-phase installations.

Our team specializes in the installation of single-phase and three-phase electrical systems, in according to your needs and requirements. Each system has its advantages, and we you we can help you choose the most suitable one for your situation.

Connection to low voltage networks.

Before starting the connection process, make sure you have all the necessary approvals and documents from your local authority or electricity distribution company. These documents may include applications, agreements, plans and technical specifications.

Contact the electricity supplier: Contact the electricity supplier responsible for the area where you want to make the connection. Your provider will provide you with specific information regarding connection requirements and procedures.

It is important to note that specific procedures and requirements may vary depending on local laws and regulations, as well as the policy of each electricity supplier.

We offer complete services for connection to low-voltage networks, which include design, execution and verification of the installation. This process is essential to ensure the supply of your property's electricity.

Protection and measurement installations.

Plan and integrate appropriate protection and safety measures. These may include earth leakage circuit breakers (IDRs), suitable fuses for short circuit protection, surge protectors and emergency shutdown systems.


Surge Protection: Consider installing surge protectors to protect equipment from dangerous voltage fluctuations. These devices can be mounted on the main electrical panel or integrated into sockets and sensitive equipment.

We understand the importance of an effective protection system and measuring devices accurate within any electrical installation. We offer complete design, installation services and maintenance for such systems.

Power lines of voltage 0.4 kV – 20 kV.

Power line voltage between 0.4 kV and 20 kV refers to a power distribution network that is commonly used in urban and rural areas to supply residential, commercial and industrial buildings.

Rated voltage: The voltage line between 0.4 kV and 20 kV has a maximum rated voltage of 20 kV (kilovolts) and a minimum rated voltage of 0.4 kV. This is the voltage at which it is designed to operate normally.

These lines are used to distribute electricity from substations to consumers. Transformer stations transform voltage from higher levels (eg 110 kV or 220 kV) to lower levels suitable for end consumers.

Execution of electrical installations.

After completing the installation of the electrical installations, we check the connections and carry out tests to ensure that everything is working correctly. We use electrical instruments used to measure and test various characteristics of a circuit such as voltage, current, resistance and continuity.
We have the ability and speed to carry out a wide range of works, from outdoor lighting installations, installation of buried and underground electrical lines, to the restoration and modernization of existing electrical installations, installation of overhead electrical connections, single phase and three phase installations, and even lines electrical with a voltage of 0.4 kV – 20 kV.

We work with the best quality materials, offering solutions that optimize costs and make energy consumption more efficient.
