List of relevant testing items of 100 inspectionsThird-party testing institutions support sample sending and door-to-door testing, mainly providing sample testing services for companies, enterprises, public institutions, individual businesses, and university scientific research, and reporting CMA/CNAS/CAL qualifications, which are true and effective.
Testing process
1, sending samples
2, checking requirements
3, targeted quotation
4, both parties determine, sign a contract, start
the experiment5, complete the experiment: the testing cycle (can be expedited) will be changed according to the sample and its testing items / methods, you can consult the engineer
6, issue a test report, and provide post-service.
This part of GB/T 12706 specifies the structure, dimensions, and test requirements for extruded insulated power cables with rated voltages ranging from 6 kV to 30 kV. This section is applicable to fixed installation of extruded insulated power cables with rated voltages ranging from 6kV to 30kV in distribution networks or industrial installations. This section is also applicable to longitudinal water resistant structural cables and their testing. When deciding on cable applications, it is advisable to consider the potential risk of radial water ingress. This section does not apply to cables with special installation and operating conditions, such as overhead cables, mining industries, nuclear power plants (inside and near the containment), as well as cables for underwater or ships. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. GB/T 156 Standard Voltage (GB/T 156-2017. IEC 60038:2009.
