Control cable quality control inspection standard
Cables play a very important role in China's power supply system. At present, the normal operation of families, companies and enterprises is inseparable from the power supply system. Power supply must be dominated by control cables. It can be said that the working quality of control cables directly affects the stability of the power supply system. Therefore, The quality control and inspection of control cable before life and construction is an indispensable work.
When customers have special requirements, it shall be strictly controlled according to their requirements. Elongation test: elongation shall be in accordance with national standards. The specific method is as follows: turn on the switch of the elongation tester.
