Baijian Testing is mainly engaged in textile, insulation, cosmetics, food, hardware industry related product testing, as well as providing product certification services, but also in the broadening of the scope of the testing industry, the laboratory issued a report can be stamped CNAS/CMA/CAL qualification seal, the report is 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 standard specifies the general technical conditions for the design, manufacturing, installation, and use of power fittings (hereinafter referred to as fittings) for overhead power lines, substations, and power plant distribution devices. This standard is applicable to hardware used for overhead power lines, substations, and power plant distribution devices with a rated voltage of over 35 kV. Hardware used in severely corrosive and polluted environments, high altitude areas, cold areas, and other conditions should also meet the relevant provisions of other relevant standards. 2 Normative References: The clauses in the following documents become clauses of this standard through reference in this standard.
