[0002] The mechanical and physical performance test of the insulation, sheath, and cable core conductor of the wire and cable includes the crack resistance of the insulation and sheath before and after aging, and the integrity verification of the conductor after impact. The traditional test method: three people participate, one person lifts the impact hammer to the specified height and then releases it to let the impact hammer do free fall to impact the tested cable, one person supervises the test personnel's reporting and the standardization of the operation, and one person records the operator's reporting and verifies the effectiveness of the process. According to the requirements of the GB / T2951.11-2008 test technical specification, the insulation and sheath of each specification of cable should be tested 20-30 times.
