Power cables have become the mainstream of urban power transmission. The cables are mainly installed under-ground,and the existing cable warning stakes have drawbacks such as weak warning,single function,high damage and loss rate,and confusion in types. Therefore a type of multifunctional urban power cable warning stake has been designed. It consists of day and night warning units,employees and social publics information units,and tipping displacement warn-ing units. It has the advantages of 24-hour warning,querying and reporting information,anti-theft and anti-tipping,as well as satisfactory appearance.
