Test method for simulating bending cracking resistance of low-smoke halogen-free sheathed cable

The invention discloses a test method for simulating bending cracking resistance of a low-smoke halogen-free sheathed cable, which comprises the following steps of: 1, coiling the cable to enable the cable to become a required cable coil; secondly, the cable coil is taken down; 3, putting the cable coil into a drying oven, heating to 90 +/-2 DEG C, and keeping the constant temperature for 5-8 hours; 4, powering off, opening the drying oven for natural cooling, observing the cracking condition, and recording whether the cable is cracked according to the cable number; 5, the temperature is increased to 90 +/-2 DEG C on the second day, and the constant temperature is kept for 5-8 h; sixthly, power is cut off, the drying oven is opened for natural cooling, the cracking condition is observed, and whether the cable cracks or not is recorded according to the cable number; and the third step to the fourth step are repeated, and the test is cycled for at least five days. According to the test method, the anti-cracking
