Low smoke halogen-free flame retardant polyolefin sheathing materials are mostly used for the external protection of butterfly lead-in butterfly cables,and copper plated steel wires and Phosphated steel wires are generally used for metal reinforcements.In the production process,the looseness of the stiffener will affect the overall performance of the butterfly lead-in optical cable.This paper analyzes and demonstrates the reasons for the looseness of the stiffener from the aspects of extrusion temperature,water tank temperature,sheath material type,stiffener type and so on.
