Larger cable during the custody of the load current

Wirecable manufacturers transport forbidden from high drop cablecable tray is provided with a cable, particularly at low temperature (usually 5 ℃below), throw, drop cable will likely lead to insulationsheath, cracking. The cable is strictly prohibitedacid, alkalimineral oil contact, to be storedthe corrosive substances. There are harmful gas damage insulationcorrosion of metal cable shall not be storage warehouse.

Cable in the custody period, should be regularly rolling (summer 3 months time, the other seasons can be deferred). When rolling down, the storage tray edge roll up, lest the bottom surface wet rot. When storing should always pay attention to cable head is intact. According to the experience, the low-voltage power line because of the load current is large, so the general press heating condition selection section,then checking the voltage lossmechanical strength; low-voltage lighting line because of its higher requirements to the thermal conditionthe mechanical strength of the high-voltage line,; then according to economic current density selection section,then check the heating conditionspermissive voltage loss;the high voltage overhead transmission lines, should also be considered its mechanical strength. If the user has no experience, should consult the relevant professional institutionspersons.
