Cat Van Loi UL 1242 Certified IMC Steel Conduit – Safety “Shield” for Metro Lines (Subway)

The product has successfully passed rigorous inspection processes and achieved UL Listed certification according to the Cat Van Loi UL 1242 standard (Edition 5, issued on November 3, 2025) with the exclusive management file number UL-US-2590177-0.

The core advantages that make Cat Van Lợi’s IMC conduit an ideal material for Metro underground stations:

  • Extremely high load-bearing and impact resistance: Featuring a thick conduit wall (DYBY product line) and a sturdy threaded connection structure, the IMC conduit provides absolute safety protection for power cable systems and train control signal cables against continuous mechanical vibrations.
  • Corrosion resistance and long-lasting durability against moisture: Advanced hot-dip galvanizing or electro-galvanizing technology helps the steel shell resist oxidation and harsh moisture in underground soils, ensuring a system lifespan of up to several decades and minimizing complex maintenance costs in Metro tunnels.
  • Fire resistance and no toxic smoke generation: This is a vital factor for underground structures. High-grade heat-resistant steel material is completely non-flammable and effectively prevents the spread of flames in the event of an electrical short circuit.

UL 797 Standard EMT Steel Conduit – Optimizing Construction Speed at Elevated Metro Stations

To meet the high-speed completion schedule of hundreds of kilometers of Metro according to the strategic orientation of the Politburo, controlling construction progress at stations, management centers, and elevated sections is a crucial challenge for contractors. Cat Van Loi’s Electrical Metallic Tubing (EMT) steel conduit (FJMX product line) is the answer to help optimize installation progress.

The product is proudly UL Listed according to the UL 797 standard (9th Edition), with certificate number UL-US-2572446-0.

Thanks to its thin-wall structure, lightweight design, and smooth surface that requires no threading, M&E engineers can easily bend it, make flexible cornering, and connect quickly via set-screw connectors or compression connectors. This helps contractors jointly constructing Metro stations save maximum time when installing ELV and elevated lighting systems while still ensuring the synchronized architectural aesthetics of modern structures.

Cat Van Loi Wire Mesh Cable Tray System – NEMA BI 50015 Standard for Substations & Metro Operation Control Centers

In addition to conduit systems, managing and distributing numerous high-power high-capacity power cable lines at Operation Control Centers (OCC), substations, and Depot technical areas of Metro lines requires a specialized, well-ventilated support structure. Cat Van Loi’s wire mesh cable trays (Metal Cable Trays – Product code: CYNW) are a top choice highly rated by design consulting units.

Cat Van Lợi’s wire mesh cable tray system has been certified by UL to fully comply with the prestigious industrial standard NEMA BI 50015 (Edition 6) and the US National Electrical Code NFPA 70 (Edition 2023), with certificate number UL-US-2571131-0 (issued on June 26, 2025).

  • Superior heat dissipation performance: The open mesh structure helps the electric train’s high-capacity power cable system dissipate heat naturally and quickly, completely eliminating the risk of overheating that causes cable insulation to melt.
  • Preventing the accumulation of pests and dust: The well-ventilated design does not allow rodents to nest and damage cables, while also making regular technical inspection and maintenance intuitive and safe.

Strategic Domestic Partner Accompanying National Traffic Infrastructure Mega Projects

The breakthrough goal of urban railway infrastructure opens up major opportunities but also sets high demands for self-reliance in high-quality construction materials right in Vietnam. Cat Van Lợi’s ownership of multiple international certifications, including UL Listed and NEMA, affirms that products manufactured entirely in domestic factories possess excellent quality, equivalent to 100% imported goods from advanced nations.

Choosing MEP material solutions from Cat Van Lợi allows major contractors and Metro project consortia not only to ensure compliance with the strictest technical acceptance standards from international supervisory consultants, but also to proactively manage delivery schedules, optimize logistics costs, and contribute to increasing the localization rate in alignment with the nation’s sustainable development policy.

According to the Politburo’s resolution setting the target to complete 200km of urban railways (Metro) in Ho Chi Minh City by 2030, the entire city is urgently accelerating the simultaneous deployment of core Metro lines to complete a modern public transport network. Faced with extremely strict technical and fire safety standards of these underground and elevated infrastructure mega projects, Cat Van Loi Industrial Electrical Equipment Manufacturing Joint Stock Company affirms its capability to fully supply through an ecosystem of electromechanical materials that meet the world’s strictest international certifications such as UL Listed and NEMA.
