Q: What are the distribution network equipment: suburbs, towns and rural areas, further allocation and supply industry, agriculture, commerce, industry and residents with special needs for electricity secto

Q: What are the general requirements for working on distribution equipment?: Distribution equipment including high voltage power distribution room, substation, power distribution transformer platform, low voltage power distribution room (box), ring network cabinet, cable branch box] outage maintenance,

Q: What is the power equipment in the distribution room?: which is mainly used for the distribution of the electric energy of the low-voltage users, and the utility model is provided with a medium voltage input line (a small number of outlets)

Q: Transmission system and distribution system: Distribution system is the power supply to the distribution load for the purpose of the general voltage level of not more than 10KV

Q: What is the difference between power supply and distribution: The two is the integration of power generation and power supply.

Q: Distribution system equipment classification: Electronic equipment - named meaning, is mainly composed of electronic components

Q: Transmission lines are not electrical equipment?: Transmission lines in the power transmission project belongs to the carrier, belonging to the power cable category, should not be called equipment

Q: What is the transmission line, what is the power distribution equipment: As the name implies, the transmission is by the power plant or power center regional power grid (sending end), to the load center power grid (by the end) of the transmission of electricity; power distribution is to be distributed by the substation or bus power down.

Q: Transmission and transformation equipment: High voltage has a very high risk, and the target electrical appliances do not need such a high voltage, which needs to reduce the voltage through the transformer

Q: Power distribution equipment should be prepared before the blackout?: Before the power failure, the person in charge or the electrical appliance technician should fill in the work order.
