SL180 Line Commissioned in South Asia — High-Speed Corrugated Conduit for Telecom Infrastructure

SL180 Line Commissioned in South Asia — High-Speed Corrugated Conduit for Telecom Infrastructure

Project Context

A national broadband mission aims to deliver high-speed fiber-optic internet to the country's population. A critical bottleneck emerged: demand for underground cable protection conduit far exceeded local production capacity.

A local manufacturer identified an opportunity to supply corrugated HDPE conduit to telecom infrastructure contractors and electrical utilities across the country. They commissioned the Suba SL180 — a high-speed, small-diameter line — to meet the explosive growth in demand.

Why the SL180

The SL180 was selected for:

  • High output: 1,500–2,000 m/shift of 110–180mm diameter conduit
  • Compact design: Suitable for shared manufacturing facilities
  • Cost-effective: Capital investment under €85,000
  • Quality: Meets local bureau of standards requirements for telecom conduit
  • Scalability: Proven path to a second unit if demand justifies

The Order

Contract finalized in Q1 2024. Delivery in Q3 2024. Installation and training completed in October 2024.

Delivery & Installation

Suba shipped the SL180 via ocean freight and road transport to the manufacturing facility. Installation took 2 weeks, with one Suba technician and the contractor's team. The operator certification program took 1 week.

Results

The machine achieved full capacity by Q4 2024. Current production metrics:

SpecificationTargetActual

Wall Thickness2.5–3mm2.8mm ±0.1mm
Output1,500–1,800 m/shift1,850 m/shift
Defect Rate<0.5%0.15%
Uptime88%92%

The manufacturer has already received orders for 500,000+ linear meters in year one, with strong demand from major telecom operators and state utility companies.

Market Impact

This represents a critical moment in the national fiber rollout: by producing locally, the manufacturer can reduce cost by 25% compared to imports, accelerating deployment timelines for telecom infrastructure nationwide.

"The Suba SL180 arrived at exactly the right moment. The market needs conduit — lots of it. We're now producing at full capacity and still can't keep up with demand. This machine is our ticket to becoming a leading supplier of telecom infrastructure." — Operations Director
