Proterial Cable America is a premier manufacturer of transit communication and supervisory trackside cable solutions, trusted by major transit authorities across the United States. Our transit and rail cables are engineered for long-term reliability in tunnels, stations, and wayside environments where safety, uptime, and maintainability matter.
Proterial Cable America understands the dynamic nature of transportation technologies and the stringent requirements for safety and performance. We specialize in providing transit and rail cables that meet relevant ASTM and UL toxicity, flame, and smoke requirements, supporting compliance with transit regulations and internal safety policies.
Transit cables are built around solid and stranded copper conductors, polyolefin insulation, and multi-pair assemblies with copper tape shielding to support 2–200 pair constructions. Low Smoke Zero Halogen (LSZH) black jackets provide an added layer of protection in enclosed spaces, helping reduce smoke and toxic emissions in the event of a fire while maintaining superior mechanical properties in harsh environments.
These designs are approved for use by the New York City Transit Authority (NYCTA) and are deployed in outdoor and tunnel installations, where cables are routed alongside high-powered cables and switches. Whether you’re specifying new infrastructure or upgrading an existing system, our transit and rail cables help you maintain reliable communication, control, and monitoring across your network.
Our transit and rail cables are designed with LSZH jackets and tested to demanding ASTM and UL flame spread, smoke generation, and transit toxicity requirements, helping protect passengers, staff, and critical infrastructure in enclosed transit environments.
Proterial transit cables have been rigorously tested and approved for use by the New York City Transit Authority (NYCTA), demonstrating reliable performance in one of the most demanding transit systems in the world and giving other agencies confidence in our designs.
Transit and rail cables are manufactured in our 300,000 sq. ft. facility in Manchester, New Hampshire. Proterial Cable America provides Build America, Buy America (BABA) compliance at the part-number level so you have the documentation you need for federally funded projects.
From conductor size and pair counts to shielding and jacketing, our engineering team can help tailor transit and rail cable constructions to project requirements or agency specifications, supporting both standard and custom designs.
Proterial Cable America manufactures supervisory and communication cables that carry critical information through a transit network. They are used to track cars, control relays and sensors, and support communication systems such as telephones, long-distance telecom, and video surveillance networks, rather than serving as power feeders.
Our transit cables are installed on tunnel walls, along tracks, and in other wayside and station environments where they run beside transit vehicles and high-powered cables. They are designed to perform in harsh conditions, including enclosed tunnels and outdoor transit infrastructure, while maintaining reliable supervisory control and communication.
In enclosed spaces like subway tunnels and train cars, LSZH cables help suppress flames without halogenated flame retardants and greatly reduce smoke and toxic emissions. That improves visibility and air quality during an emergency, giving passengers and first responders more time to see signage, locate exits, and evacuate safely.
Proterial transit cables use 16–22 AWG solid and 19 AWG stranded copper in multi-pair constructions that carry a large number of control and data circuits while keeping overall diameter manageable in tunnels and stations. They are engineered for harsh transit environments, with LSZH jacketing and mechanical features selected to support the wide temperature range and potential crush conditions specified for transit use.
