Fire Hazard Research of Aluminum Cable Joint

On the basis of fire hazard simulation study of aluminum cable joint, it reveals that large contact resistance at cable joint can induce high temperature, and easily ignite combustibles then catch fire. Through macro-examination and metallographic analysis about the melted marks of aluminum cable joint, it clarifies the formation mechanism of the melted marks, and the corresponding preventive measures which can prevent cable fires, provide a practical and reliable scientific basis to guarantee the safe operation of power system.
