| Abstract: | With an introduction of the technology of linearly movable contact-weld adopted in Urban Mass Transit,the author compares linearly movable contact-weld with temporary base fixing contact-weld on the experience gained in Guangzhou Metro Line 2,and points out that linearly movable contact-weld has higher efficiency,lower expense and is convenient in construction.He also argues that for the use in a wider field,the technology details and controu quality standard shall be further improved. |
