President Trump warned that China should not supply our transformers because they can install mechanisms that can shut our power off.

He wrote an Executive order stopping the use of Chinese transformers. Biden immediately reversed Trumps order. Idiot.. "Chinese power equipment can be embedded with software and hardware that can be remotely accessed, enhancing China’s ability to commit cyberattacks. Because power transformers are huge and weigh between 100 and 400 tons, it is not easy to identify embedded software or hardware. There is also a potential hardware risk since counterfeit items can be easily put into large power transformers."
