New Cable Designed To Deter Copper Thieves 630

"Pervasive thefts of copper wire from under the streets of Fresno, California have prompted the city to seal thousands of its manhole covers with concrete. In Picher, Oklahoma, someone felled the town's utility poles with chain saws, allowing thieves to abscond with 3,000 feet of wire while causing a blackout. The theft of copper cables costs U.S. companies $60 million a year and the FBI says it considers theft of copper wire to be a threat to the nation's baseline ability to function. But now PC World reports that a U.S. company has developed a new cable design that removes almost all the copper from cables in a bid to deter metal thieves. Unlike conventional cables made from solid copper, the GroundSmart Copper Clad Steel Cable consists of a steel core bonded to a copper outer casing, forming an equally effective but far less valuable cable by exploiting the corrosion-resistance of copper with the conductive properties of steel. 'Companies trying to protect their copper infrastructure have been going to extreme measures to deter theft, many of which are neither successful nor cost effective,' says CommScope vice president, Doug Wells. 'Despite efforts like these, thieves continue to steal copper because of its rising value. The result is costly damage to networks and growing service disruptions.' The GroundSmart Copper Clad Steel cable is the latest technical solution to the problem of copper theft, which has included alternatives like cable etching to aid tracing of stolen metal and using chemicals that leave stains detectable under ultra-violet light. However the Copper Clad Steel strikes at the root of the problem by making the cable less susceptible to theft by both increasing the resistance to cutting and drastically decreasing the scrap value."

大意是铜涨价了,盗贼多了
去年美帝某些盗贼用电锯砍倒电线杆,偷走3000英尺(约1公里)长的铜线,造成俄克拉荷马某镇断电
加州某城市(Fresno)由于偷电缆过于严重,被迫把电缆维修孔(类似下水道入口)封死
FBI认为电缆盗窃已经威胁到了国家的正常运转
用铜包钢可以从技术上追踪盗贼,并且铜包钢难于切割,废料价值低,可降低对盗贼的诱惑力 |
