Permanently Lubricated (PLB) HDPE Duct Pipes
RDSO / Spec No.
N/A (Standard Commercial / Industrial Specification)
Application
Indian Railways (S&T / Telecom) & Telecom Networks - Optical Fiber Cable (OFC) Ducting
Product Specifications & Details
PLB HDPE Ducts (Permanently Lubricated High-Density Polyethylene Ducts) are high-capacity underground conduits specifically designed for blowing and pulling Optical Fiber Cables (OFC). Manufactured using high-density polyethylene integrated with an internal solid lubricant layer, these ducts minimize internal friction during cable installation. The rugged HDPE outer structure provides superior crush and impact resistance against heavy earth loads, ensuring long-term protection for subterranean telecommunication and railway signaling networks.
Key System Features & Advantages
- Low Coefficient of Friction: Permanent internal lubricated lining significantly reduces pulling force during long-distance OFC blowing.
- High Earth Load Endurance: Exceptional crush and impact resistance capable of withstanding heavy sub-surface soil and traffic loads.
- Environmental Crack Resistance: Outstanding Environmental Stress Crack Resistance (ESCR) and temperature stability.
- UV & Weather Protection: Formulated with high UV protection for outdoor storage and exposed installation points.
- Lightweight & Moisture Proof: Non-reactive to water for easy cleaning via water streams; lightweight for rapid field deployment.
- Subterranean Flexibility: Crack-proof smooth finish designed for inter-city networks, field trenches, and sidewalk conduits.
Primary Network Applications
