Q:CHINT group in the transmission and distribution equipment to do it?: not only is the previous low, now from energy production to transportation to use to control a complete solution.

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:What is the transmission line, what is the power distribution equipment: Usually an overhead line, a very small number of lines (or some of them) is a cable line

Q:Are electric wires and cables belong to distribution equipment?: Wire rod products for the transmission of electric (magnetic) energy, information and electromagnetic energy conversion.

Q:What is the role of transmission system and distribution system in power grid: Such as water resources are concentrated in the river basin water level drop larger place, fuel resources in coal, oil, gas.

Q:What are the two power distribution equipment?: The two equipment is the equipment for the control, protection, monitoring and measurement of the work of the primary equipment.

Q:DC transmission equipment: DC screen commonly known as intelligent maintenance free DC power supply screen, referred to as DC screen, the general model is GZDW.

Q:Main equipment of high voltage direct current transmission: It is composed of two or more converter bridges, which can realize the AC DC AC converter.

Q:What are the distribution network equipment: The transmission function of the power plants issued by the electricity to power consumption areas, or between adjacent grid power to send each other

Q:AC distribution equipment including distribution box: Connect the power supply, transformer, converter and other equipment for load distribution box, and monitoring
