Cables attached to the bracket shown in Figure 2. All the metal frame grounding. Continuous detection means: in the test current through all core cables, three single-phase transformers, and has sufficient capacity is maintained at the test voltage reaches the maximum allowable leakage current is 3A. At the other end of the cable to connect each wire a lamp, and close 0.25A load current at the rated voltage cable. 2.3.1: Heat: A strip of burner can burn to a length of 400mm 400mm of cable sample. Burner assembly can be adjusted to provide a bright flame temperature of 650 ± 40 ° C, 2.3.2: temperature measurement: diameter of 2mm armored thermometer placed under the surface of the cable 2.3.3: test flame temperature: 650 . C ± 40 ° C 2.3.4: water: a nozzle mounted on a test stand, in the middle of the burner to pressure 250KPa 350KPa, in the vicinity of the sample spray 0.25 liters to 0.30 liters per square meter per square meter. water. This rate requires measurement with a collection tray, this disk has enough depth to make his major axis parallel to the axis of the cable and centered. This tray about 100mm wide and 400mm long. 2.3.5: Sample: Sample is greater than 1500mm from the finished product, and the bending test has been done at ambient temperature, both ends of the cover layer is removed and the sheath of 100mm. At both ends of the cable wires and electrical connections should be in accordance with the manufacturer's recommendations for proper disposal 2.3.6: test voltage: 200 ~ 1000V adjustable Third, resistance to mechanical shock and fire: the test device shown in the following sections, the assembly is secured in slotted frame corresponding position. 3.1 cable fixed on one side of a vertical wall, heat-resistant non-combustible material is fixed to the plate; 3.2 transformer fuse connection with lights to indicate the circuit is a continuous wall heat 3.4 3.3 shock device and its installation wall is made of a heat barrier burning material and fixed on the two horizontal beams, one in the upper plate and the other one in the bottom plate. This board about length 900mm, width 300 mm, thickness of 9 mm, and the total weight of the wall (ie panels plus support frame) was 10 ± 2 kg .. Each girder is about 1m, 25mm square steel tube. If you need a filler material, you need to place it inside the steel beams. Steel beams must be fixed in the upper plate, so the upper edge is flush with the upper surface and the plate. Steel beams and the outer edge of each plate has a horizontal hole, its exact location is determined by the needs of specific support pad and support frame. 4 by a rubber bushing wall bonded to the frame, the bushing diameter of approximately 32mm thick 20mm. Continuous detection means: in the test current through all core cables, three single-phase transformers, and has sufficient capacity is maintained at the test voltage reaches the maximum allowable leakage current is 3A. At the other end of the cable to connect each wire a lamp, and close 0.25A load current at the rated voltage cable. 3.4.1: Heat: A strip of burner can burn to a length of 400mm 400mm of cable sample. Burner assembly can be adjusted to provide a bright flame temperature of 650 ° C, 3.4.2: temperature measurement: diameter of 2mm armored thermometer thermometer thermometer at a distance through the wall is the wall 8mm to 10mm. Temperature measured by the following procedure: In the end of the mild steel rod diameter 3mm ± 5% Length 300mm tied a thermometer, so that it can measure the temperature of the rod. Grab it with the stick close to the flame from the flame is maintained at 40mm to 50mm. The temperature when the flame temperature of 950 ° C, the steel bar in the 10s to 20s temperatures can reach 400 ° C, when the flame temperature of 650 ° C, the temperature in the 20s to 40s rod can reach 400 ° C. 3.3.3 : test flame temperature and time: the test temperature required to select from the table below: X 650 ± 40 ° CY 750 ± 40 ° CZ 950 ± 40 ° C 3.4.4: vibration means vibration device consists of a mild steel bar (diameter 25mm ± 5%, long 600mm ± 5%).
