February 15, 2008 -- Arnco Corp. has introduced its Fiber-Guard Low Smoke Zero Halogen (LSZH) conduit. Flame-retardant with low-flame propagation, the product meets National Fire Protection Association and UL-1685 standards for confined space applications and lowers installation costs compared to metallic conduit, according to the company.
When exposed to flames, Fiber-Guard LSZH generates low smoke, creating better visibility; and does not produce halogens, making it safe to use in confined spaces such as transportation tunnels and other areas where it is desirable to eliminate the release of halogen gas by-products.
Due to the heightened awareness of the negative effects of halogen when exposed to flames, the LSZH product is designed to reduce acid combustion that can corrode sensitive electronic parts, lessening harmful side effects to humans and equipment.
Fiber-Guard LSZH is rugged yet flexible for easy installation, maintains Arnco. The conduit can be used as an innerduct and pulled into steel conduit or into cable tray, or directly attached to tunnel walls.
The product is available in standard sizes ranging from 1 inch to 3 inches in diameter, in schedules 40 or 80, and SDRs 11 and 13.5. The optional pre-lubed conduit offers a lower coefficient of friction for faster and easier cable installation, while protecting the cable from high tensile stress during installation. Fiber-Guard LSZH is also resistant to cold temperature impact and is available with color stripes or special markings for easy identification.
"Fiber-Guard LSZH can be used in applications where communication cables are present as it will not interfere with radio frequency (RF) signals like metallic conduit will," comments Scott Wells, sales manager, dataComm products, Arnco.
