Power Fittings Manufacturers Share The Causes And Elimination Methods Of Heating In Power Fittings
The fixed support type of power fittings includes suspension wire clamps, tension wire clamps, Stainless steel & fixing nail, and protective fittings.
Fixed support fittings mainly meet mechanical properties, such as nominal breaking load and grip requirements.
Commonly used materials are: malleable cast iron, gray cast iron, carbon structural steel (steel, steel plate), high-strength aluminum alloy, etc.
The reasons for the heating of power fittings are magnetic: hysteresis and eddy current loss heating and closed circuit circulation loss heating, which will increase with the increase of current (load).
Elimination method: increase the distance between iron parts (heating body) and conductors; disconnect the closed circuit and install insulating pads to eliminate circulating current; adopt electromagnetic shielding; adopt phase-separated closed busbar.
