BS 7846-2009 "Electric cables -6001000V thermosetting insulated armored fire-resistant cables that emit small amounts of smoke and corrosive gases when affected by fire - Specification".Product Parameters
1. Test station: 1 station, measuring one sample at a time.
2. Test object size: Length>1200mm.
3. The sample holder L has a total of 3 wire support rings. During the test, place the sample on the wire support ring and clamp it with two measuring fixtures. Applicable to 4 Test whether the integrity of the cable or optical cable is maintained during fire supply under a flame temperature not lower than 750 ºC.
5. Blowtorch: Our company's self-made Venturi air propane mixed type blowtorch has a length of 500mm.
6. Flame temperature: adjustable from 450 ° to 950 °.
7. Combustion gas: Propane with a purity of 98% (provided by the customer).
8. Combustion supporting gas: compressed air. (The air pressure must reach 10Mba or above) to be provided by the customer.
9. Temperature sensing system: imported stainless steel K-type thermocouple. (Material temperature resistance above 1100 ° C).
10. Air flow rate: 80L/min.
11. Propane flow rate: 0~99.99s/m/h can be set arbitrarily.
12. Ignition device: Automatic ignition.
13. This machine is equipped with a strong exhaust system. After the test is completed, the strong exhaust fan can quickly exhaust the exhaust gas from the box.
14. The chassis adopts a double-layer partition structure, filled with high-temperature insulation cotton in the middle, effectively reducing the temperature of the outer wall during the test process to<45 ° C
15. Power requirement: AC380 (± 10%) V/50HZ.
16. Machine operating power: 1KW.
17. The exhaust system is installed at the top of the chassis, which can effectively and quickly exhaust exhaust exhaust gas. There are several air intakes at the bottom, which can ensure that during the test process
The oxygen content inside the box makes the test results more accurate.
18. Install a front door with tempered glass windows to observe the test situation at any time. During the experiment, the door was in a closed state,
Prevent harmful substances generated by combustion from polluting indoor air.
19. Temperature measurement system: Two K-type thermocouples are installed on the left and right sides 70mm above the spray lamp, with the two thermocouple heads 250mm apart.Function
1. Combustion chamber: Internal size: 3M × 3M × 3M has a total of 27 cubic meters.
2. Control box: The control box is made of stainless steel plate, processed and formed by CNC machine tool, and has a beautiful and elegant arc shape.
3. Combustion device: This device is composed of 30 * 30 aluminum profiles, which is lightweight, beautiful, and easy to move and clean.
4. Control system:
Adopting a relay control system, all electronic components are from leading domestic brands, which can better ensure the performance and detection accuracy of the machine.
5. Continuous detection device: During the test, the current is allowed to pass through all the cores of the cable, and the three single-phase transformers have sufficient capacity to maintain the test voltage
Reaching the maximum allowable leakage current of 3A. Connect a lamp to each core wire at the other end of the cable and load it close to 0.25A at the rated voltage of the cable
Current. When there is a short circuit/open circuit in the sample during the test, a signal is output.
6. The equipment has the following safety protection devices: power overload, short circuit protection, and control circuit overload protection.Conditions
1. The ground is flat, well ventilated, and free from flammable, explosive, corrosive gases, and dust.2. There is no strong electromagnetic radiation source nearby.3. Leave appropriate maintenance space around the equipment.4. Temperature: 5 ºC~30 ºC5. Air pressure: 86-106kpa. AC380V/50HZ.6. Allowable voltage fluctuation range: 380V ± 10%.7. Allowable fluctuation range of frequency: 50HZ ± 1%.8. The user's installation site is required to equip the equipment with corresponding capacity air and power switches, and this switch must be independent and dedicated for the use of this equipment.When the equipment is not working, the ambient temperature should be maintained within+0-45 ºC, and the vibration combustion device should be placed outside the combustion chamber.
