Below are a few of the major advantages: Life Equivalent to copper in corrosion resistance Fatigue Resistance Superior to annealed copper Handling Flexible and manageable like copper, yet more robust and durable than dead soft annealed copper Mechanical Higher mechanical strengths minimize physical damage during installation and service Weight Lighter than copper by 8.5% for equivalent sizes Theft Resistance Zero scrap value Approximate Short Term Fusing Currents for 40% CCS (amps) 26,250 (sec)CyclesCMILCMILCMILCMILCMILCMILCMILCMIL 0.053330,426164,807130,700153,50496,54376,56360,71848,15238,18734,86721,92913,792 0.16233,647185,293146,947116,53692,419108,54386,08054,13834,04924,6559,752 0.212165,213131,022103,90782,40365,35076,75238,28124,07617,4346,896 0.318134,896106,97984,84067,28253,35862,66831,25719,65814,2358,9535,630 0.424116,82392,64758,26846,20954,27227,06917,02412,3287,7534,876 0.530104,49082,86652,11641,33148,54224,21115,22711,0266,9354,361 0.63695,38647,57637,73044,31322,10213,90010,0656,3303,981 0.74288,31044,04634,93141,02620,46212,8699,3195,8613,686 0.84882,60741,20232,67538,37619,14112,0389,5478,7175,4823,448 0.95477,88238,84530,80636,18118,04611,3509,0018,2185,1693,251 16073,88636,85229,22534,32417,12010,7678,5397,7974,9033,084 212052,24526,05820,66524,27112,1069,6007,6146,0385,5133,4672,181 Approximate Short Term Fusing Currents for Copper (amps) 16,510 (sec)CyclesCMILCMILCMILCMILCMILCMILCMIL 0.053317,543254,034190,526158,771134,361106,55584,50353,14626,50810,485 0.16224,537179,629134,722112,26895,00775,34537,58018,7447,414 0.212158,771127,01795,26379,38667,18053,27726,57313,2548,3365,243 0.318129,636103,70977,78264,81854,85343,50121,69710,8226,8064,281 0.424112,26889,81556,13447,50437,67318,7909,3725,8943,707 0.530100,41680,33350,20842,48933,69616,8068,3825,2723,316 0.63691,66745,83338,78730,76015,3427,6524,8133,027 0.74284,86742,43335,90928,47814,2047,0844,4562,802 0.84879,38639,69333,59026,63913,2876,6274,1682,621 0.95474,84637,42331,66925,11512,5279,9346,2483,9292,471 16071,00535,50230,04423,82611,8849,4245,9273,7282,345 212050,20825,10421,24416,8488,4036,6644,1912,6361,658 125 CommScope Way Statesville, NC (USA) 28625 Tel +1-828-324-2200 or 800-982-1708 Fax: +1-828-431-9811 bimetals@commscope.com www.commscope.com © 2012, CommScope Inc.
