Cable route survey
This process involves mapping the optimal path for laying underground cables, taking into account geographical features, existing infrastructure, and potential obstacles to ensure minimal disruption and maximum efficiency.

These high-voltage cables are designed for transmitting large amounts of electricity over long distances underground. They are insulated to handle high voltages up to 400kV and are often used in urban areas or to connect substations to the grid.
This involves various tests, such as insulation resistance testing, continuity testing, and high-voltage testing, to ensure the cable's integrity, performance, and safety before and after installation.
This refers to the process of connecting two electrical cables (jointing) or connecting the cable to equipment or devices (termination). It requires specialized techniques and materials to ensure a reliable and safe connection.
Also known as grounding, this process ensures that the electrical system or equipment is connected to the earth to prevent electric shocks and protect against electrical faults by providing a path for fault current to safely dissipate into the ground.
This involves detecting and pinpointing the location of faults in underground cables, using techniques such as time domain reflectometry (TDR) or other specialized equipment to identify issues like short circuits, breaks, or insulation failures.
