Product Introduction
TY-NHMC Fire-Resistant Busway| Low Voltage Fire-Safe Bus duct
TY-NHMC Fire-Resistant Busway uses inorganic mineral materials as insulation materials, which have a fire resistance temperature of over 950°C and excellent insulation performance. Its shell is composed of cold-formed thin steel profiles. The surface is galvanized and coated with fire-retardant paint, and the side plates on both sides adopt the unique double-layer hollow structure independently developed by our factory, which are filled with fire-proof cotton and fire-proof boards. Through the tight hollow design, high-temperature gas or open flames are effectively prevented from directly entering the interior of the busway. The joints adopt special fire-resistant insulating components, ensuring reliable and convenient connection.
Key Features of Fire-Resistant Busway：
- Compact Sandwich Design
A compact, sandwich-style structure with closely arranged conductors minimizes space, improves overall heat dissipation, and reduces temperature rise. - Three robust layers:
- Inner Layer： Full -length mica tape for insulation.
- Middle Layer：Fireproof cotton and insulation boards.
- Outer Layer：One-piece rolled galvanized steel shell delivers a neat appearance, high mechanical strength, and excellent electrical performance. The surface is coated with fire-retardant paint. Both side plates use our factory’s unique double-layer hollow design for extra rigidity and insulation.
- Flexible connections
Flexible joints with special fire-resistant insulating components improve adaptability and ensure reliable, easy connections.
