, Respectively, the statistics of construction equipment, need coefficient method for load calculation, select the transformer and wire cross-section, the rational design of the three distribution with two protection devices, the implementation of electrical safety technology and management measures

Statistics, respectively, and construction equipment to be used for load calculations factor Law, select transformers and wire cross-section, reasonable design level 3 distribution and two levels of protection of the device, the power of the technology and security measures, as well as managing the

Counts the construction equipment separately, the use needs the method of correlates to carry on the load computation, chooses the transformer and the wire section, designs three levels of power distributions reasonably with two level of protection equipment, the realization uses electricity the saf

Statistics of construction equipment, respectively, need coefficient method for load calculations, selection and conductor cross section of transformer, reasonable design of three-level power distribution with two-level protection equipment, implementation of safety technology and management measure
