3M company has completed its first enhanced composite aluminum core wires ACCR field testing.
In 2001, 3M company in Ek Silva Binjiang company is located in Minneapolis, Xinjiang station installed a 115 kv transmission line.
And the company researched and developed ACCR compound aluminum wire for field tests, to prove its product to strength and elasticity in harsh environments.
It is also the history of the power grid's first composite reinforced aluminum conductor field testing. Since 2001.
The transmission line has been operating for 13 years until the end of 2014 was removed for later study by 3M company.
In 2005, in the transmission line, 4 years after successful operations of 3M company decided to ACCR composite conductor is commercially available.
Moreover, since Ek Silva Binjiang station, 3M company also has this product in other power companies and the American oak ridge national laboratory for field testing.
However, the Binjiang station of the transmission line is the longest test operation.
3M company said that the test results show that ACCR aluminum conductor composite conductors and the performance of various performances are desired, even more than expected.
The aluminum conductor does not appear in the process of operation of the wire tensile strength loss signs of fracture strength rating in the 108% to 110%.
At the same time, under the condition of perennial exposure in the air, wire tension measurement is the best performance expectation, which is 2990 LBS.
Electrical marketing technology manager of 3 m company Herve Deve, said "test has proved that ACCR composite wires in a long time, under extreme environmental conditions can maintain its superior performance."
