The Heat protection aluminum foil corrugated conduit is a type of conduit that is designed to protect wires and cables from high temperatures. 
It is made of aluminum foil and has a corrugated design that allows it to expand and contract with changes in temperature. This type of conduit is commonly used in industrial settings where high temperatures are present, such as in foundries, steel mills, and glass manufacturing plants. 

It is also used in automotive applications to protect wiring from the heat generated by engines and exhaust systems.
