贯通西安—成都—重庆(西成渝)的微波通信干线,全长633.6公里,是四川的通信大动脉。守护这条大动脉入川北大门的广元微波通信局,连年征战于崇山峻岭之间,为微波通信事业的发展,为振兴四川经济作出了贡献。随着改革开放的不断深入,通信事业为经济发展和社会进步发挥着举足轻重的作用。西成渝微波通信干线的正式开通,解决了四川长期以来存在的出川长途通信难的问题。这条干线拥有1800条话路、传送一套彩色电视信号及四路伴音等多种通信能力,是“让四川走向世界,让世界了解四川”的桥梁和纽带。微波通信信号是由许多微波站来传送的,微波站大都建在地势较高的山区。西成渝干线在我省境内设有15个微波站,广元微波通信局
Through the Xi’an - Chengdu - Chongqing (West into Chongqing) microwave communications trunk, a total length of 633.6 kilometers, is the communication artery in Sichuan. The Guangyuan Microwave Bureau, which guarded this artery to the north of the Chuanbei, raced for years in the mountains of Chongshan, contributing to the development of the microwave communications and rejuvenating the economy of Sichuan. With the deepening of reform and opening up, the cause of communication plays an important role in economic development and social progress. West Chengdu-Chongqing microwave communication trunk was officially opened, to solve the Sichuan has long been out of Sichuan long-distance communication difficult. With 1800 telephones and a variety of communication capabilities such as color television signals and four-way sound, this trunk line is the bridge and link for “letting Sichuan visit the world and let the world know Sichuan.” Microwave communication signals are transmitted by many microwave stations, most of which are built in high mountain areas. West into the Chongqing-line in the province with 15 microwave stations, Guangyuan Microwave Bureau
