Shelves devices can be connected by welding or screw assembly. Shelves and housing should have sufficient mechanical strength and stiffness distribution box size, should be able to withstand the mechanical and thermal stresses when the installed components and the resulting short circuit and shall constitute sufficient consideration to prevent a large eddy current loss caused by magnetic path. While not due to equipment lifting, transportation and other conditions affecting the performance of the device. In order to ensure corrosion Jinnan distribution box, the device should be used in anti-corrosion materials or exposed surfaces coated with anti-corrosion layer distribution box installation, but also consider the use and maintenance conditions. Power Meter, is for power monitoring and energy management needs power system, industrial and mining enterprises, public facilities, intelligent large public buildings and design. It all commonly used high-precision measurement of electrical parameters, such as three-phase voltage, phase current, active power, reactive power, frequency, power factor, four-quadrant power, etc, to the use of high visibility LCD display instrument measurement parameters and power system operation information. Power meter function, model range, price is not the same distribution box manufacturers, energy metering programs are also varied, therefore, it should be a reasonable option, achieve better value for money.
