3. Materials:

3.2 Copper cover ends: to be a good electrical conductivity of the base material of brass.

3.3 Copper cover treatment: copper plating line cover portion indicated last if you add "S" who shall represent silvering.

3.4 Copper cover strength: minimum 720g-cm torque copper lid and ontologies.

4. Operating environment

4.1 Working temperature: -20 ℃ to + 70 ℃

4.2 weldability temperature: 260 ℃ ≤3 seconds 350 ℃ ≤1 seconds

5. Electrical Characteristics:

5.1 Load capacity: 100% of rated current measurement can continue without any melting phenomenon energized.

5.2 Temperature characteristics: tests performed on 1½ hours, and continue to maintain the original plus current test once every ten minutes, continuous measurement three times, the temperature should not rise, even if the use of thermal measurement method (Tbermocouple mcthod) the body temperature rise The following 70 ℃, if using a thermometer measuring method (Tbermocouple mcthod) is below 50 ℃.

5.3 Resistance Measurement: Adjust the fuse of the rated current value of 10% when using a high impedance voltmeter buck value fuse ends, the resistance to the computer or electrical measuring bridge mode (rated 2½ amps (inclusive) or more, without Measure the resistance value).

5.4 Overload fuse: When 200% of rated current value should be within a maximum 60 seconds to fuse, and the fuse continues after pressing to five minutes, may not happen any shock phenomenon. Refer to the following table.

6. Mechanical properties

6.1 tensile strength Terminal Strength: 1.1 pounds when applying axial tension to both ends of the wire (or the cap) after five minutes no loose or damaged phenomenon.

6.2 ① fixed end of the rotation strength copper head, and the other end is applied to 720 g / cm force about shaking, copper head not loose any body damage ② end of the wire is bent 90 degrees, the body of the original axis of rotation of 360 degrees (five seconds). after three different directions of rotation, the wires or junction damage does not occur.

6.3 bending strength Bending Strength: lead after two in the opposite direction of the bending (bending 90 degrees with that of a bent folded in situ) damage does not occur.

6.4 Packing: 200PCS (bag) 5000PCS (a small box) 20000PCS (a box)
