What is voltage company?

Could you please clarify what you mean by "voltage company"? Voltage typically refers to the electrical potential difference between two points in a circuit, measured in volts. It's a fundamental concept in electrical engineering, not directly related to companies or businesses in the traditional sense. However, if you're referring to a specific company that operates in the field of electrical engineering, power distribution, or renewable energy technologies that involve voltage regulation or management, that would be a different matter. Could you please provide more context or details about the "voltage company" you're asking about?
