Description

WS Series Intelligent protective meter box , use new environmentally engineering plastics polycarbonate (PC) manufacturing , with highinsulation performance , good performance of transparent , UV resistance , aging resistance , acid rain , salt spray resistance , low andhigh temperature resistance , anti- shock performance, and good ventilation, anti-rain , anti-heat and other functions , the normal life ofmore than 20 years .WS series of meter box with the integrated design concept, one to sixteen of power meters and the entire measurement loop containerclosed box in the integration of not only occupy a small space , easy to install and manage , and be able to stop the stealing by touchmeasuring device, to prevent stealing behavior .Reserved through the back of the bolt hole can be easily and securely installed in the concrete wall. Box components, compact structure,reasonable layout , alignments, smooth and clear . Cover by hooking, special screws and padlock and cabinet interlock , only theelectrical control officers to take special spanner and key before they can open . Crystal clear cover , and reading number zoom upfunction, the power control officers do not need to open the box can directly see the various types of anomalies of the box , therebyenhancing exclude security risks in the electricity , so that "the safe use of electricity , preventing the main " management objectives.

The scope of products and conditions of use
