PE Cable Conduit & Subduct Pipes — Outside diameter 110 mm
Polyethylene Conduit in Cable Infrastructure Protection
Modern electrical grids and telecommunication networks require underground raceways that provide long-term protection against moisture, corrosive soil chemistry, and mechanical stress. Polyethylene cable protection conduits encompass two dedicated systems: telecom subducts (P009) and electrical power ducts (P010).
These non-conductive, dielectric conduits form isolated raceways in direct-buried municipal and cross-country utility trenches, protecting high-voltage, medium-voltage, and optical fiber cables from rodent damage, water ingress, and surface traffic surcharge.
Fiber Optic Subducts & Electrical Cable Ducts
Telecom Subducts (P009) are produced in outside diameters from OD 32 to 63 mm in extended coil lengths of 500 m to 2000 m. An ultra-smooth inner bore minimizes pulling friction, enabling long-distance pneumatic fiber optic cable jetting. Color-coded options (black, orange, green, blue, red, grey) facilitate line identification within multi-way duct banks.
Power Cable Ducts (P010) range up to 200 mm for distribution power cabling and sub-station feeds. Available in coils and 6 m straight lengths, they supply structural crush resistance against earth compaction without requiring concrete encasement in standard trench depths.
Conduit Trenching, Bedding & Duct Couplers
Installing cable duct networks requires a uniformly graded, compacted trench bed to prevent localized undulating sags that could obstruct cable transit. Long continuous subduct coils virtually eliminate intermediate joints, ensuring a watertight raceway.
When joining straight sections or connecting pull-boxes, gastight and watertight push-fit mechanical couplers are employed to maintain pressure containment during high-pressure pneumatic cable blowing.
PE Cable Conduit & Subduct Pipes — Frequently Asked Questions
What is the purpose of different color codings in telecom subducts?
Multiple color codings (such as orange, green, blue, and red) differentiate distinct fiber optic cables, speeding identification within jointing chambers and manholes.
What is the maximum coil length available for subducts?
Subducts in 32 mm and 40 mm sizes can be supplied in continuous coils of 500 m, 1000 m, up to 2000 m to eliminate underground jointing in long-haul fiber routes.
Are cable protection conduits electrically insulating?
Yes. Polyethylene possesses high dielectric strength, acting as a natural electrical insulator that prevents stray currents from discharging into surrounding soil.
