Introducing the underground joint trench for electrical wiring, which is smaller and more maneuverable compared to conventional cab systems!
The underground wiring plan, which secures a comfortable walking space and improves urban scenery, began with the "Phase 1 Underground Wiring Plan" using the cab system from fiscal year 1986. Then, starting in 1995, the "Phase 3 Underground Wiring Plan" transitioned from the cab system to the more compact and flexible structure known as 'C.C. BOX (joint utility trench).' Due to its significant role as a public facility, it reduces the burden on power and telecommunications operators and facilitates their entry into the joint utility trench. 【Features】 ■ Smaller and more flexible compared to the conventional cab system ■ The compact utility housing facility is embedded at a shallow depth from the surface, making construction easy ■ New cables can be added from the branching point without the need to excavate the road each time ■ Its significant role as a public facility reduces the burden on power and telecommunications operators, making entry into the joint utility trench easier *For more details, please refer to the PDF document or feel free to contact us.
