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 thatof 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.
