TW90/30 folding box system Wichmann ® Z-19.15-1022. Fire-resistant S90 or S30 sealing of cable ducts in walls. The cable box consists of a galvanized sheet steel housing, lined with fire protection agent that foams up in the event of a fire. The fire sealing is functionally separate from the cold smoke seal and works independently of the seal. The functionality of the cable box is not interrupted by subsequent installation work. The folding cable box is the innovative solution for sealing off existing cables and lines. It is delivered as a flat element and can be installed quickly without tools. Simply fold by hand at the specified bending edges and assemble around existing cables and lines to form a finished cable box. Then mortar or plaster it into the wall. The included EasyFoam foam plugs are used for cold smoke sealing. They have a much lower density and are therefore easier and quicker to process than, for example, fire protection plugs. The cables and the housing are sealed with a permanently elastic sealant (e.g. silicone or acrylic) or with EasyFoam fire protection assembly foam B1. Installation in light partition walls and in solid walls from 100 mm thick. The TW90/30 folding box can be 100 percent filled. It is approved for sealing off cables and lines of all types up to 20 mm in diameter and plastic conduits in accordance with DIN EN 61386 up to 35 mm in diameter. When filling, no gaps are required between cables, cables and conduits and conduits between each other. In addition, the sealed cable box can be installed without filling as a reserve bulkhead. The cable box can be filled at any time while maintaining full functionality. Assembly is carried out in accordance with the enclosed assembly instructions or ABG Z-19.53-2444. No processor validation is required for installation.
