In our digital era, the role of electrical and telecommunication installations is more vital than ever before. These installations are critical infrastructures for residential, commercial, and industrial spaces, enhancing connectivity, safety, and overall functionality. Whether it’s about managing the low-voltage lighting system of a residential building or maintaining the high-voltage substation of an industrial complex, electrical and telecommunication installations play a fundamental role.

Extra Low Voltage Installations
Extra low voltage (ELV) installations include a wide range of systems designed to enhance safety, security, and communications within a building. These systems typically operate on lower voltages (50V AC or less) and include:
- Fire detection and alarm systems: These are designed to quickly identify and alert occupants to potential fire threats.
- Telecommunications equipment: Devices and systems that enable the transmission of information over significant distances.
- Security and surveillance systems: These offer real-time monitoring of premises to enhance security.
- CCTV: Closed-circuit television systems allow for the visual monitoring of different areas within a building or property.
- Intruder alarms: These alert property owners and security personnel to unauthorized access.
- Access control systems: These systems limit access to specific areas within a property, enhancing security.
- Building Management Systems (BMS): These centralized control systems manage and monitor the building’s mechanical and electrical equipment for comfort, safety, and efficiency.
Low Voltage Installations
Low voltage installations (below 1000V AC) are typically associated with power and lighting requirements for various types of buildings and installations. This includes:
- Commercial and industrial buildings.
- Hotels, lodges, and other hospitality facilities.
- Hospitals and healthcare facilities.
- Residential premises.
In addition, low voltage installations also include:
- Transformers and switchboards: Vital for stepping down high voltage power to low voltage levels suitable for usage.
- Uninterruptible Power Supplies (UPS): Provide backup power in case of main power failure.
- Automatic Voltage Regulators/Stabilizers (AVR/AVS): Ensure consistent voltage levels and protect appliances from voltage spikes.
- Power Factor Correction banks (PFC): Improve energy efficiency by reducing the amount of reactive power in the system.
- Control Panels and Systems: Centralized systems that control electrical equipment.
- Rising mains: Vertical power supply systems in multi-storied buildings.
- Earthing and lightning protection systems: Safeguard electrical systems and building occupants from electrical faults and lightning.
- Generators: Provide power during outages.
Other services
Additional services can be offered within the realm of low-voltage installations, such as power analysis, which involves evaluating the performance and efficiency of a power system, and structured cabling, which organizes a building’s entire communication network in a single infrastructure for ease of management.
High Voltage Installations
High voltage installations include the installation, maintenance, and testing of:
- Complete substations: Facilities where electricity is transformed from high to low voltage (or vice versa).
- Transformers: Devices that adjust voltage levels for transmission or use.
- Switchgear: Equipment used to switch off equipment and clear faults downstream.
- High Voltage metering: Measures the amount of electric energy consumed at high voltages.
- High Voltage breakers: Safeguard electrical circuits by interrupting an electrical overload or short circuit.
- Underground and overhead transmission/distribution lines: Carry electricity from power plants to consumers.
- Cable jointing/terminations: Join or terminate cables in the transmission and distribution of electricity.
Electrical and telecommunication installations serve a pivotal role in modern life. They encompass an extensive range of systems and equipment designed to enable communication,
