Electrical Cable Pipes
The local authorities of Singapore, namely the Power Grid and the Singapore Telecom use uPVC pipes as protection to the electrical and telecommunication cables respectively. The electrical cables are encase in SS141 (Equivalent to BS3505 or AS1477) Class B uPVC pipes before being haunch in concrete. The pipes serve as a formwork to the cable installation and as a protection against future excavation and soil movement. It also allows for future connection/extension to be made.
