Can you convert electricity to 50 years old at a time?

Substation can only be done at the age of 50. According to the query recruitment network, the primary substation is an industry that works in a high-voltage electric field environment. Its working environment is harsh and dangerous, it needs to stand for a long time, operate heavy equipment and bear high-intensity working pressure. Therefore, from the physical condition, before the age of 50, power transformation is not a career.
