Test of Cable

The rapid development of domestic economy is inseparable from the security guarantee of the power system. In the power system the demand for wires and cables is also increasing. All kinds of inferior wire and cable products flooded the whole market and seriously affected our engineering and personal safety. NG28 can test the raw materials, finished products and accessories of wires and cables. This test can ensure the safety of products and provide support for product improvement and quality improvement.

? Q&A

How long does the test period take？

The normal period is 5-7 working days (except the time when the sample is in the test chamber). If you need urgent help, please contact our sales or customer service.

What are the sample requirements for the low temperature winding test of the cable?

The diameter of the low temperature winding test cable shall not exceed 10 mm. Before testing it is needed to confirm the diameter of the sample to be tested and the required load.

What are the sample requirements for the cold impact test of the cable?

The diameter of cables for cold impact test shall be range 4mm to 75mm.

Before testing it is needed to confirm the diameter of the sample to be tested and the required weight of drop hammer.

How is the result of pressure test at high temperature for wires and cables evaluated?

The pressure, temperature and heating time on the blade should be confirmed before pressure test at high temperature for wires and cables. The evaluation is based on taking the maximum intermediate value for the indentation depth of the tested sample.
