Concrete products: Electric wire joint trench (branching pit)

Concrete products: Electric wire joint trench (branching pit)

Underground intersection, a solid starting point. A junction that divides trust.

In the cable duct (CCBOX), the junction box (special section) that serves as the "key" for branching and pulling in cables is located. The most complex process in the construction of the cable duct is concentrated in the "junction box." Our precast junction boxes combine strength to withstand harsh underground environments with smart workability that dramatically shortens construction time on site. They robustly support the urban power supply network from underground. We accept inquiries for custom manufacturing tailored to site conditions.
