In this paper

the properties of thermoplastic flame retardant polyolefin materials were tested

and the Fourier transform infrared spectroscopy

differential scanning calorimetry and thermogravimetric spectra of the materials were tested and analyzed.The material formulation is locked.The single vertical burning experiment of butterfly-shaped cable was discussed.At the same time

the smoke density and corrosion of the cable were briefly studied

and experimental reference data were provided for the production of different types of butterfly-shaped cables.
