CAT VAN LOI IMC STEEL CONDUIT CERTIFIED TO UL 1242 – AN ANCHOR OF SAFETY FOR METRO LINES (SUBWAY)

The product has successfully passed rigorous inspection procedures and achieved UL Listed certification under the UL 1242 standard (Edition 5, Issue Date 2025-11-03) with the exclusive management number UL-US-2590177-0.

Core advantages that make Cat Van Loi IMC conduit an ideal material for underground Metro stations:

• Extremely high load-bearing and impact-resistant capacity: Featuring a thick conduit wall (product category DYBY) and a robust threaded connection structure, IMC conduit helps protect the internal power and train control signaling cables with absolute safety against continuous mechanical vibrations.
• Durable corrosion and moisture resistance: Premium hot-dip galvanizing or electro-galvanizing technology helps the steel shell resist harsh oxidation and moisture underground, ensuring a system lifespan of up to decades and minimizing maintenance costs, which are typically highly complex in Metro tunnels.
• Fireproof and zero toxic smoke emission: This is a life-or-death factor for underground structures. The high-grade heat-resistant steel material is completely non-flammable and effectively prevents the spread of flames should an electrical short-circuit occur.

1. EMT Smooth Steel Conduit with UL 797 Standard – Optimizing Construction Speed at Elevated Stations

To meet the rapid deployment timeline of hundreds of kilometers of Metro lines under the strategic direction of the Politburo, controlling construction progress at passenger stations, management centers, and elevated sections is a pivotal challenge for contractors. Cat Van Loi Electrical Metallic Tubing (EMT) smooth steel conduit (Product Category: FJMX) provides the ideal answer to accelerate installation schedules.

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

Thanks to its thin-wall design, lightweight structure, and smooth unthreaded surface, electrical engineers can easily bend, offset angles flexibly, and perform quick connections using screw-type or compression-type couplings and connectors. This enables joint-venture contractors executing Metro stations to maximize time savings during the installation of extra-low voltage (ELV) systems and elevated lighting systems while ensuring the integrated architectural aesthetics of modern facilities.

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

In addition to conduit protection systems, managing and distributing large volumes of high-capacity power cables at Operation Control Centers (OCC), substations, and technical Depot areas of Metro lines requires a dedicated, well-ventilated support structure. Cat Van Loi Wire Mesh Cable Trays (Product Designation: CYNW) are the top choice highly rated by international design and engineering consultants.

The wire mesh cable tray system by Cat Van Loi 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 (2023 Edition), under certificate number UL-US-2571131-0 (Issued on 2025-06-26).

• Superior heat dissipation performance: The open mesh structure allows the high-capacity power cable systems of the electric trains to dissipate heat naturally and rapidly, completely eliminating the risk of overheating that causes cable sheath melting.
• Prevention of rodent nesting and dust accumulation: The well-ventilated design prevents rodents from nesting or damaging the cables, while ensuring that routine maintenance and technical inspections are visually straightforward and secure.

3. A Strategic Domestic Partner Accompanying National Transport Infrastructure Mega-Projects

The goal of expanding the urban railway network unlocks major opportunities but also presents strict demands for localizing high-quality construction materials directly within Vietnam. The fact that Cat Van Loi simultaneously possesses globally recognized international certifications—UL Listed and NEMA—confirms that products manufactured entirely at its domestic plant exhibit outstanding quality, 100% equivalent to imports from advanced nations.

By choosing MEP material solutions from Cat Van Loi, large contractors and Metro project consortia not only ensure compliance with the most stringent technical acceptance standards set by international supervising consultants, but also fully control delivery schedules, optimize logistics costs, and contribute to increasing the domestic localization rate in line with the country's sustainable development policy.

According to the Politburo's Resolution setting the goal of completing 200km of urban railway (Metro) in Ho Chi Minh City by 2030, the entire city is urgently accelerating the simultaneous implementation of core Metro lines to perfect a modern public transportation network. Facing the extremely strict fire safety and technical standards of these major underground and elevated infrastructure projects, Cat Van Loi Industrial Electrical Equipment Manufacturing Joint Stock Company asserts its capacity to fully supply the demand with an ecosystem of mechanical, electrical, and plumbing (MEP) materials that have achieved the world's most rigorous international certifications, such as UL Listed and NEMA.
