Main application scenarios of PT cabinets

In power plants and substations, PT cabinets are used to measure, protect, and monitor the voltage of equipment such as generators, transformers, and busbars, providing important safeguards for the safe operation of the power system.

Besides the protection level, what other factors affect the applicable environment of the switchgear?

Besides the protection level, what other factors affect the applicable environment of the switchgear?

Rated Voltage: Different usage environments have different voltage requirements. In industrial production, large motors, electric furnaces, and other equipment usually require higher voltages, such as 6kV, 10kV, etc., so they need switchboards that match the corresponding rated voltage.

In what environments can a distribution cabinet with an IP54 protection rating be used?

These locations typically contain a certain amount of dust, but the dust particles are relatively large and non-corrosive. An IP54 enclosure prevents large amounts of dust from entering the cabinet, protecting the internal electrical components from dust damage and ensuring normal operation.
