实行“四到户”管理，优点和好处很多，我们应结合实际工作，将这件人民群众欢迎、电业企业长期受益的管理方式搞好。但由于其新，难免存在不足。　　一是实行销售到户，使电业部门的安全责任明显增加。过去电业部门主要负责10千伏以上线路的维护和管理工作，现在直接到户，低 There are many advantages and benefits in the implementation of the “four-to-house” management. We should combine the actual work and do a good job in managing this long-term benefit of the people and the electric power companies. However, due to its newness, it is inevitable that there are shortcomings. First, the implementation of sales to households has led to a significant increase in the safety responsibilities of the electricity industry. In the past, the electrical industry department was mainly responsible for the maintenance and management of lines of more than 10 kV.
