The measurement results of the bridge load testing experiment were heavily influenced by the field environment. Based on the field test results of strain which were affected by simulated outside temperature, it was proposed that the compressed enameled wire could replace the traditional rubberized wire and shielded cable in bridge load testing experiments. This was supported by abundant data collected from the in-situ measurements and the results of these measurements were positive. As bridge-arm lead in the electrical resistance strain testing system, the compressed enameled wire was more stable than the rubberized wire.
