Shorter installation times and lower total costs make RED-E-DUCT the right choice for large-scale government and municipal projects. An investigation of four high-voltage cable lines (110 kV/220 kV) of the Zhuhai Power Supply Bureau of Guangdong Province showed that 5.35 km of electrical duct bank was laid along a 15.25 km long linea considerable proportion. All RED-E-DUCT products are rated for HS20 and HL93 loading. Directional changes in duct banks shall be made with 20 minimum radius bends. Duct banks shall not route water from manholes into buildings, or contain traps between manholes where water may accumulate. Rapid installation and immediate backfill make RED-E-DUCT ideal for projects where restoring traffic access is imperative. Slope duct banks downward, toward manholes, and away from buildings, a minimum of 6 inches per 100 feet. RED-E-DUCT’s extreme strength and performance allows for much shallower bury depths when compared with cast-in-place, resulting in lower costs and fast rate of construction. Immediate backfill means faster access to above ground work to keep projects moving forward. Provide adequate sleeves for 4 sets of 12-way, 5 ducts with minimum 6 between ducts. Include concrete knockout panels for conduit entrance and sleeve for ground rod. RED-E-DUCT shines in congested areas where schedule savings can yield big results on a project. Description: Underground utility structures, constructed in place, complete with accessories, hardware, and features. 4 PVC if for loop feed service and encase in red concrete. RED-E-DUCT’s low thermal resistivity adds peace of mind by reducing the risk of premature cable failure due to inadequate backfills, poor installation practices and high thermal temperatures. underground conduits two 4 schedule 40 PVC runs minimum use four. Complete below grade work faster with RED-E-DUCT. Concrete-Encased Ducts: Duct lines shall consist of single or multiple duct assemblies encased in concrete, and installed with top of duct bank not less. Standard precast duct bank sections and stub-ups reduce labor requirements, improve safety and provide maximum construction flexibility. ![]() Rapid installation and backfill permits above ground work to start earlier. ![]() Low thermal resistivity concrete ensures duct banks in high heat applications can be trusted to perform. Whether building a new facility or replacing existing infrastructure, RED-E-DUCT’s immediate backfill capability means work completes faster and site congestion is reduced. Some ideal applications of RED-E-DUCT precast electrical duct banks include: Engineered for efficiency, RED-E-DUCT is the solution to the complex underground duct banks demanded by oil, gas and chemical facilities, power generation, industrial facilities, airports, data centers, and road/highway projects.
