A qualified cable requires not only multiple production processes, but also multiple testing steps. Only a cable that has completely passed the testing can be called a qualified cable. For example, for Shenghua Cable, cables need to go through 5 testing steps before they can be delivered to customers.

5 tests for Shenghua Cable:

1. Electrical performance testing

The detection of electrical performance mainly includes the detection of conductor DC resistance, insulation resistance, voltage experiment, and insulation core to core voltage experiment. These tests are quite important for Shenghua cables because they will directly affect the temperature, lifespan, voltage drop, and operation safety of Shenghua cables during electrification operation.

2. Mechanical performance testing

The mechanical performance testing of Shenghua cables mainly tests the tensile strength and elongation at break of insulation and sheath plastic materials, including before and after aging, as well as the bending test, bending test, load breaking core test, insulation core tear test, static bending test, etc. for finished soft cables. These tests are also very important as they ensure that Shenghua cables have sufficient flexibility and performance stability at high temperatures.

3. Performance testing of insulation and sheath materials

The insulation and sheath material testing of Shenghua cables includes thermal weight loss, thermal shock, high temperature pressure, low temperature bending, low temperature stretching, low temperature impact, flame retardant performance, etc. The main function is to test the performance of cable insulation and sheath materials, such as whether they will degrade at high temperatures and become brittle and brittle at low temperatures.

4. Sign inspection

The fourth step of Shenghua Cable is to check whether the markings, models, and other information on the packaging are complete and clear. The general standard requirement is that Shenghua Cable packaging should be accompanied by labels or markings indicating the product model, specifications, standard number, factory name, and place of origin. The specifications include rated voltage, number of cores, and nominal cross-sectional area of conductors; The surface of the cable should be printed with continuous markings of the manufacturer's name, product model, and rated voltage. The above content should be clear enough to facilitate customer viewing.

5. Structural dimension inspection

Finally, Shenghua Cable also needs to undergo structural dimension testing, including insulation and sheath thickness, thinnest thickness, external dimensions, etc. These have specified values in the industry. If they do not meet the requirements, there may be safety hazards, so these tests are also very important.
