Rated for the job
RED-E-DUCT components are encased in Contech’s proprietary high compressive strength, fluidized thermal concrete, and is manufactured under controlled conditions at Contech’s certified fabrication facilities. The result is a new benchmark for performance to support critical underground infrastructure.
Superior Thermal Resistivity
RED-E-DUCT offers low, consistent thermal resistivity (Rho values) that can help power engineers design power distribution systems with greater confidence and reduced costs. 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.
Conduits are surrounded by Contech’s proprietary high strength thermal concrete that provides a stable environment that protects expensive high voltage cables.
Low concrete thermal resistivity for better thermal performance
Low thermal resistivity (Rho values) gives designers peace of mind to select the proper cable size, potentially reducing cable costs without compromising design integrity.
Heavy Load Performance
Rated to Accommodate HS20 and HL93 Truck Load Conditions
All RED-E-DUCT components are encased in high compressive strength concrete. The high-strength concrete, coupled with the patented shear key joint design ensures the installed system will perform under load conditions imposed by heavy truck, crane, rail, roadway traffic, or earth cover.
All RED-E-DUCT installations meet the load performance requirements defined by HS20 and/or HL93 specifications without requiring supplemental reinforcement.
Patented Joint System
The patented joint system utilized by RED-E-DUCT offers the right solutions for both watertight and non-watertight applications, without the need for epoxies, solvents, or glues.
FOR WATERTIGHT APPLICATIONS
An integrated gasket within the conduit bell housing seals against the spigot, providing reliable, permanent watertight protection.
FOR NON-WATERTIGHT APPLICATIONS
A separate bell/spigot slip joint is used where watertight joints are not required.
Integrated Shear Key
A unique, integrated shear key feature ensures that joined RED-E-DUCT sections will withstand shear forces at each joint location. The unique shear key design permits proper joint deflection to accommodate poor soil beds or future settlement issues.
