Product Details
ZY6014D Bunched Cable Vertical Flame Spread Tester
Brief Introduction
The Bunched Cable Vertical Flame Spread Tester simulates real-world vertical shaft and tray fires to guarantee your cable bundles won’t easily propagate flames.
Highlights / Outstanding Features / Characteristics
- Grouped Cable Testing: Specifically engineered to test clustered or bundled cable layouts rather than single wires.
- Critical Fire Metrics: Measures the exact vertical flame spread rate, total heat release, and localized smoke production.
- Risk Mitigation: Delivers precise data on fire propagation potential, helping engineers design safer electrical containment systems.
- Regulatory Compliance: Provides the certified testing environment required to meet international vertical burn standards.

Main parameters
| Parameter | Details |
|---|---|
| Test Box | Self-standing, (1000 ± 50) mm × (2000 ± 50) mm × (4000 ± 50) mm. The rear and both sides are thermally insulated (heat transfer coefficient: 0.7 W/m²·K). Made of high-grade stainless steel, with a 65mm thick thermal insulation mineral fiber core and an external baking paint coating. |
| Air Supply | Adjustable air inlet to maintain (5000 ± 500) L/min before and during tests (Complies with GB/T 18380.31). |
| Fire Suppression | A water spray system automatically extinguishes the fire after a predefined test duration (1 hour). |
| Ignition Source | Automatic ignition via high-voltage pulse. |
| Exhaust System | Located at the top of the combustion box, ensuring uniform gas discharge. Multiple air inlet holes at the bottom regulate oxygen levels. |
| Observation Window | Toughened glass window installed in the front door for real-time monitoring. The door seals completely during testing to prevent combustion gases from escaping. |
| Flame Temperature | Adjustable from 450°C to 950°C. |
| Combustion Gas | Propane with a purity of 95% (prepared by the customer). |
| Power Supply | AC220V. |
| Chassis Size | L1000 × W2000 × H4000 mm (Complies with IEC 60332-3-10, Clause 5.1). |
| Control Box | Made of baking varnish, CNC-machined for precision. |
| Blowtorch System | Stainless steel, corrosion-resistant, and anti-rust. Features 242 holes (1.32mm diameter) with 3.2mm spacing, arranged in three staggered rows for stable burning. |
| Control System | Uses a relay control system with high-quality domestic electronic components. |
| Safety Features | Includes power overload, short circuit protection, and control circuit overload protection. |
| Combustion Control | Includes air flow meter, propane flow meter, regulating valve, ignition device, and temperature measuring device. |
