AI Technical Summary
Technical Problem
Existing cable support structures, particularly ladder-type cable racks, lack sufficient heat-resistant protection, leading to potential deformation and damage when exposed to high temperatures, which can compromise cable performance.
Method used
A covering structure for ladder-type cable supports, comprising sequential application of a first fire-prevention sheet, a heat-expandable fire-resistant sheet, and a second fire-prevention sheet, fixed with fasteners having claw portions, ensuring overlapping layers for enhanced heat protection.
Benefits of technology
The covering structure provides excellent heat-resistant protection by forming a uniform carbonized insulation layer, effectively suppressing temperature rise and maintaining cable integrity during fires.
