Building Wire: is a type of wire used in a residential building or house that uses aluminum electrical conductors. Aluminum offers a better conductivity-to-weight ratio than copper, and is therefore also used in grid wiring, including overhead transmission lines and local distribution lines, as well as power wiring for some submarines, automobiles, airplanes, and elevators. Since the late 1800s and early 1900s, utilities have been using aluminum wire for power transmission on the grid. It has cost and weight advantages over copper wire, and aluminum wire remains the material of choice in transmission and distribution applications.
Insulation material: polyvinyl chloride (PVC), polyethylene (PE), rubber sheath, nylon insulation
- Copper conductor: Due to the high electrical conductivity, good ductility and thermal conductivity of copper, and high compatibility with electrical insulators, the cables of electrical equipment are mainly made of copper conductors.
- Aluminum conductor: The price of aluminum is lower than that of copper, and it is more commonly used. Aluminum will form an insulating oxide layer on the surface. It can be used by coating the aluminum conductor with an antioxidant paste at the joint, or by applying it during the installation process. A mechanical termination designed to break through the oxide layer to solve.
