| Description : |
Features:
1 integration design, adopt multilevel pressure sensitive clamping parallel technology
2 large flow-through capacity, low residual depression, fast response time
3 with the separate equipment of loading overcurrent, overheating and failure
3 total protecion of commen code and differential module
4 indicate the working state and count the overvoltage, offer the alarm and remote communication
5 Varistor connected in series with gas discharge tubes to eliminate leakage current, higher security
6 complete connected line
7 Th box is made of high quality steel, fire-retardant and anti-corrosion
SY series power lightning protection box is classified by the experiment of classifying of SPD I/II level, and as a complex three-phase power thunder spd, applying to the I level and II level of the loaded devices on the power curcuit from the damage caused by overvoltage even the direct lightning flash, it is installed on the LPZOA-2 interface.
