High tension (HT) and low tension (LT) electrical works are essential components of electrical infrastructure, encompassing the installation, maintenance, and operation of electrical systems that handle different voltage levels. HT electrical works typically involve voltages above 1 kV, commonly used for transmitting electricity over long distances and powering large industrial facilities, while LT electrical works handle voltages below 1 kV, serving distribution networks and end-users such as residential and commercial buildings.In HT electrical works, specialized equipment and safety measures are required to handle high voltages safely and efficiently. This includes the installation of transformers, switchgear, and transmission lines to step up voltages for efficient long-distance transmission and step down voltages for distribution to substations or industrial facilities. Maintenance of HT systems involves regular inspections, testing, and repairs to ensure optimal performance and reliability, as well as compliance with safety regulations.On the other hand, LT electrical works focus on the distribution of electricity to end-users at lower voltages. This includes the installation of wiring, distribution panels, and circuit breakers within buildings to deliver power to electrical outlets, lighting fixtures, and appliances. LT systems also require regular maintenance to identify and address issues such as faulty wiring, overloaded circuits, and damaged components to prevent electrical hazards and ensure uninterrupted power supply.Both HT and LT electrical works play critical roles in providing safe, reliable, and efficient electricity supply to meet the needs of various sectors, including residential, commercial, and industrial applications. By adhering to best practices in design, installation, and maintenance, electrical professionals ensure the integrity and performance of electrical systems, contributing to the overall functionality and safety of the built environment.
