Understanding How Conduit Sealants Perform in the Presence of Fire
Safety regulations such as the NESC (National Electrical Safety Code) and NEC (National Electrical Code) typically require the sealing of conduits to protect critical systems and components from water, gases, and rodents. While there are various sealant options available to meet codes and requirements, a common type that is used are expanding urethane sealants. These types of seals are used in conduit systems that house electrical and communications networks within transportation hubs, office buildings, industrial plants, data centers, hospitals, and other critical infrastructure locations. Safety and reliability are crucial within these settings, and any opportunity to prevent disruption of electrical or communications operations is vital.
Fire is a risk that threatens any structure whether it comes from energized equipment within the building or from external means. Conduit networks and routes within buildings are a potential pathway for fire to spread if they are not properly sealed or if they are sealed with a material that does not have the proper fire performance rating. The use of building materials that limit the spread of smoke and flame and reduce the danger of fire is not only a best practice, but often code. In this article, we examine how expanding foam sealants are assessed for fire performance based on industry standards and testing. The intent is to provide a better understanding of the differences between sealant materials based on their fire performance testing certification so that network owners, engineers, and installers can provide the right protection against fire.
Wooden poles rot over time due to wet conditions caused by rain, frost and organic growth.
Wood preservation treatments are being discontinued for EH&S reasons.
The preservatives always slowly drain through the wood, leaving the top surface un-protected
TE Connectivity's Pole Top Protector Covers (BCIC-PTC) protect the degradation of wooden poles by preventing water or moisture from entering the pole, this increasing the life-span.
The BCIC-PTC covers are versatile and cost-effective. They can cover the pole diameters from 165 mm to 470 mm. The covers have a round design to fit the pole shape. They are manufactured from a versatile and durable UV-stabilized polyethylene material that ensures an excellent product performance.
