Description
The "1.5" in the cable's name refers to the cross-sectional area of the conductors, which is measured in square millimeters (mm²). In this case, the conductors have a cross-sectional area of 1.5 mm². The twin cable configuration means that the two conductors are parallel to each other within the same sheath.
\n
\nThe purpose of the twin cable is to carry electrical current from a power source, such as a distribution board or consumer unit, to various electrical outlets, switches, and appliances within a building. The brown conductor is typically used for live or phase connections, carrying the alternating current (AC) supply voltage. The blue conductor is used for neutral connections, providing a return path for the current back to the power source.
\n
\nThe additional bare or green/yellow conductor in the cable is known as the earth or grounding conductor. Its purpose is to provide a safe path for electrical faults or leakage currents to flow into the ground, protecting people and property from electric shock hazards. The earth conductor is connected to grounding points throughout the electrical system, such as metal enclosures, water pipes, or grounding rods.

\nThe flat design of this type of cable makes it easier to install in situations where space is limited, such as behind walls or under flooring. It also allows for more flexibility during installation compared to round cables.
