  • How to prevent fires from blocking cable trays

    How to prevent fires from blocking cable trays

    Stopping the fire inside the tray is the most effective way to prevent broader system impacts. Direct Low Pressure (DLP) clean agent systems offer a practical solution for detecting and suppressing fires inside cable trays. A heat-sensitive detection tube runs along the tray. What Happened: On 6 January 2013, a fire erupted in the Huidong Constellation Building (Jinan, China). The resulting barrier retards the transmission of smoke, fire, and toxic gases from spreading between adjacent rooms and floors for the rated time period. Where cables pass through shafts, walls, slabs, or enter electrical panels or cabinets, openings shall be tightly sealed. FireResistant Solutions provides cable tray covering and fire-protection systems designed to safeguard electrical and data infrastructure in commercial and multifamily buildings.


  • How to seal cable trays and wires

    How to seal cable trays and wires

    Electrician's putty, also known as duct seal, is a preferred material for direct wire sealing because it is a non-hardening, pliable, clay-like compound that can be easily molded around cables inside junction boxes or conduits. Just peel off layers until the module fits. One area efficient Roxtec seal can replace up to 32 traditional cable glands. The built in spare capacity makes it easy to open up the seal and change. Cable entry seals play a crucial role in protecting electrical systems and enclosures from environmental hazards like dust, moisture, and temperature changes. Whether you're new to the world of cable management or looking to upgrade your current setup, this beginner's guide will explain everything. Our Raychem cable entry seals (CES) are water-tight, heat-shrinkable products providing long-term sealing for cable penetrations into panels, junction boxes and through bulkheads.
