How to test the performance of the power cord plug

How to test the performance of the power cord Qiaopu
Column on the power cord as the main pillar of the vertical, there is no slope, the construction of the routine use of templates, select the section of the main design template based on the size of the column.
Either high or low power cord arrangement legs, one leg control method used for casting, as in every part of such coordination, the project square leg height, half-open on the same side.
Template support and Tic-Tac-fir, wood or metal stent wire reinforced hydraulic adjustable connecting rod bearing.
Root controller can be used to open or direct control of the steel tape theodolite angle method.
Conductivity -? To 20 ℃, 1-meter-long, cross-sectional area of ​​one square millimeter standard copper wire resistance 1/58ohm basis (0.017241 ohms) 100% of the so-called conductivity. The greater the resistance, the lower the conductivity, are inversely proportional.
Bending - the end of the fixed network, with the weight straight down the other side of the line and then bend back and forth off of 180 so far, curved fold, strong resistance to bending.
Breaking strength - tensile test samples and the maximum load for breaking the weight or force.
Tensile strength - Tensile test, the unit area under the pull-off force of specimen fracture.
