Cyclect Engineering completed the electrical infrastructure works for the Jurong Island to Pioneer Transmission Cable Tunnel (JIPTC), a 5.2km underground cable route handling 400kV and 230kV power transmission.
The tunnel connects Jurong Island — Singapore’s petrochemical and energy hub — to the Pioneer substation on the mainland. Delivering high-voltage electrical infrastructure within a cable tunnel environment requires precise installation discipline, careful coordination with civil and structural works, and stringent safety management given the confined working conditions.
This project placed Cyclect among a small number of contractors with direct experience in high-voltage transmission infrastructure in Singapore, extending its credentials in critical national energy systems.
