PERFORMANCE TESTING ��Mechanical performance: the grip force of the wire clamp is 1/10 bigger than the break force of the lead. It comply with GB2314-1997. ��Temperature rise performance: under the condition of big current, the temperature rise of connector is less than that of connection lead. ��Heat circle performance: 200 times per second, 100A/mm2 big current overload, the change of connection resistance is less than 5%. ��Waterproof insulation performance: under water for 30cm, input over 3.5kV voltage for 1 min, no break out. ��Resistance to corrosion performance: under the condition of SO2 and salt fog, it can do three times of fourteen days circle testing. ��Environmental aging performance: under the circumstance of ultraviolet. radiation, dry and moist, expose it with change of temperature and heat impulse for six weeks. ��Low temperature installation test��Connector and cable cooled down in a freezer or climate chamber below -10�� screw the nut until contact occurs......
