Cable and wire testing instrument machine equipment
ZY6014D whole bundle cable vertical ignition tester
ZY6014D whole bundle cable lighting tester is strictly manufactured in accordance with GB/T18380.31-2008 and other specifications, used to identify the vertical installation of the whole bundle of cable wire or optical cable under the required standards to prevent the vertical spread of flame working ability; It is used to measure the flame retardant grade of flame retardant cable.
The flame retardant grade of the whole bundle cable conforms to the flame retardant grade of GB/T19666-2019
The non-metallic material volume of the specimen is 7L/m, and the fire supply time is 40mm.
The non-metallic material volume of the specimen is 3.5L/m, and the fire supply time is 40mm.
The non-metallic material volume of the specimen is 1.5L/m, and the fire supply time is 20mm.
The non-metallic material volume of the specimen is 0.5L/m, and the fire supply time is 20mm.
Strictly in accordance with GB/T18380.31-2008 design scheme, GB/T18380.33, GB/T18380.34, GB/T18380.35, GB/T18380.36 experimental methods.
Machinery and equipment components:
1, wire and cable wholesale manufacturers test equipment
a) Environmental test chamber: The test equipment is an independent shell with a width of (1000±100)mm, a depth of (2000±100)mm and a height of (4000±100)mm.
b) The thermal conductivity of the wall and both sides of the environmental test chamber should be about 0.7W. m-2? K-1 thermal insulation layer, 1.5mm thick USU304 stainless steel plate, the middle is covered with 65mm thick thermal insulation phenolic insulation board, 1.5mm thick USU304 stainless steel plate.
2, air energy heat pump:
a), the air inlet is equipped with a digital display gas rate wind speed meter, the gas pressure of the gas is (5000±500)L/min;
b) After the end of the experiment: if the test piece is still lit one hour after the termination of the fire supply, it is equipped with an alarm and the equipment to forcibly terminate the lighting of the rain;
3, the type of steel ladder: wide (500±5)mm basic steel ladder width (800±10)mm wide steel ladder material is USU304 stainless steel;
4, discharge purification equipment:
a) The upper end of the environmental test chamber is equipped with a digital display anemometer to ensure that the water flow of the wind is lower than 8M/S, which is not easy to harm the total gas flow in the test chamber;
b), smoke collection and dust cleaning equipment: use SUS304 stainless steel plate, diameter of 800mm height to width ratio of 3500mm.
5. Ignition source:
a), type: The ignition source shall include one or two belt propane gas natural gas furnaces and supporting facilities steam flow meters and venturi tube switching valves. The fire supply surface should be drilled with 242 flat metal sheets with a diameter of 1.32mm, the management center spacing of such holes is 3.2mm, divided into three rows of overlapping sequence, each row of 81, 80 and 81, spread over the tolerance specification of 257×4.5mm. In addition, a row of small round holes are opened on each side of the fire spitting plate, which can maintain the smooth ignition of the flame.
b) Each gas furnace is equipped with accurate equipment to control the propane gas and gas injection rate. Can choose flowmeter or flowmeter.
6. Ignition source:
a), the gas furnace should be placed horizontally, away from the front surface of the cable test specimen (75±5)mm, away from the bottom of the environmental test chamber (600±5)mm, and symmetrical with the center line of the steel ladder. The gas furnace ignition point should be located in the management center between the two cross crotches of the steel ladder, and less than 500mm from the bottom of the specimen.
