AI Technical Summary
Traditional electric heat tracing wires cannot dynamically adjust the heat output according to the ambient temperature or the actual needs of the object being heated, which may lead to localized overheating, energy waste, and safety accidents.
A temperature regulation mechanism is installed inside the device box of the electric heat tracing cable. Utilizing a bimetallic strip and magnetic cylinder structure, it contacts the object being heated through a clearance hole and automatically adjusts the heating power to achieve dynamic adjustment.
This avoids localized overheating caused by continuous heating, reduces the incidence of safety accidents, and improves energy efficiency.
