In daily life, people determine the strength of the power is to look at the size of its voltage, current, power, if the voltage and current power is large, then it is a strong power, on the contrary, if it is small, then it is weak. Then people wonder what is a strong electrician, what is a weak electrician? In fact, the strong electrician is engaged in more than 24v current electrical equipment to maintain the maintenance and other aspects of the work, while the weak offense, then, is to deal with 60 volts below the DC current electrical appliances and electrical equipment and other malfunctions. But for both, both belong to the electrician, are for human electrical equipment.
Nowadays, the current dominates the development progress of our living society, such as people's general communication needs to be supported by the current, and the current allows people to have a bright night. So electricity is very important for human beings, it can illuminate the way forward for people, and become the people's indicator. If there is no electricity in the era, it is a backward and undeveloped society. Electrician's maintenance and protection so that people have the security of electricity, will not worry about strong will hurt life, and do not have to worry about weak power is not big enough to maintain the power to use.
Strong electrician is the use of more than 20v alternating current is a strong electrician, generally his involvement is more extensive ah, in the large factories inside the high voltage system of more than 6000 volts will be used to the strong current, small aspects such as the use of lighting inside the home can be used to the strong current. Strong current is more widely used than weak current, and the exchange frequency between strong and weak current is also different.
For the weak electrician, his use of words is also relatively wide, such as household appliances in the computer, chargers, cell phones and other electrical equipment are used to the weak electrician. In the future development, strong electrician and weak electrician will no longer exist, are collectively referred to as electricians, and their salaries are relatively high, but they are generally more difficult to get a license.
