NWC1 Series Self-healing Low Voltage Shunt Capacitors
and heat dissipation of the capacitors under high temperature environment and keep the capacitors away
from heat source .
3 . 4 Transportation conditions : The capacitors should be transported within original package ( packed
in foam box ). The product should be handled carefully during transportation , to prevent the capacitor
body from deformation due to collision . The product should be placed on upper level when loaded
onto the truck . The capacitor assembly must be placed vertically during transportation , with an
inclination less than 30 degrees .
