Ask the seniors who work in the switchgear factory, what is the primary and secondary treatment of high and low voltage switchgear, and is it promising?

As an ordinary worker, as a secondary wiring worker, it is a good job with certain technical content. The technical content of primary wiring is less than that of secondary wiring. Especially when assembling some control cabinets, secondary wiring still needs rich knowledge and experience. Secondary wiring workers are also relatively scarce in the power distribution industry.
