ASTP-120 cable national standard inspection refers to the ASTP-120 cable inspection service in accordance with the national standard. ASTP-120 cable is a commonly used power cable, which is widely used in power systems, buildings, transportation and other fields. In order to ensure the quality and safety performance of ASTP-120 cables, the state has formulated relevant inspection standards.
The service content of ASTP-120 cable national standard inspection mainly includes the following aspects of testing:
1.Appearance inspection: Detect whether the appearance of the cable is damaged, deformed, aging and other phenomena to ensure the appearance quality of the cable.
2.Conductor detection: detect whether the conductor of the cable meets the requirements of the standard, including the material, cross-sectional area, resistance value of the conductor, etc.
3.Insulation testing: check whether the insulation layer of the cable meets the requirements of the standard, including the thickness of the insulation layer, voltage resistance, etc.
4.Water blocking performance testing: detect whether the water blocking performance of the cable meets the requirements of the standard to prevent leakage accidents during the use of the cable.
5.Mechanical property testing: check whether the mechanical properties of the cable meet the requirements of the standard, including tensile strength, bending performance, etc.
Through the ASTP-120 cable national standard inspection service, users can know whether the quality and safety performance of ASTP-120 cable meets the national standards, so as to ensure that there will be no safety accidents during use. At the same time, the ASTP-120 cable national standard inspection service can also provide a certain quality assurance, providing a reliable basis for the user's purchase and use.
