Wenchang Cable officially launches high-performance CMP plenum communication cables certified to UL 444. This cable series is rated 300V with a maximum continuous working temperature of 75°C, 90°C or 105℃and passes the FT6 flame-and-smoke test, meeting standard requirements for North-American building wiring systems.
CMP is the highest fire-safety grade for communication cables. It is specially designed for installation in ceiling return-air spaces, raised-floor areas and all ventilation plenum environments. Manufactured with high-quality low-smoke and flame-retardant materials, Wenchang CMP cables feature excellent self-extinguishing performance. Compliant with FT6 requirements, they effectively control flame spread and reduce smoke generation during fire accidents.
With stable dielectric properties and uniform insulation structure, the cables maintain reliable electrical performance during long-term continuous operation. CMP cables are fully downward-compatible, which means they can replace CMR-rated cables and ordinary communication cables for higher standard project wiring solutions.
Wenchang CMP cables are widely used in commercial buildings, medical facilities and data-center projects across North America. All products pass strict online spark-testing and batch-quality inspections, with complete UL-certification records to support local-project inspection and acceptance.
