Application areas:
It is mainly used for insulation protection of intermediate and terminal joints of high-voltage cables with flame retardant requirements, insulation protection of various busbars, and corrosion protection and wear resistance of various pipelines.
Product Description
Product Introduction:
Flame-retardant thick-walled pipes are made from polyolefin flame-retardant materials through radiation modification. The products possess excellent properties such as thick-walled flame retardancy and high insulation. They are mainly used for insulation protection of intermediate and terminal joints of high-voltage cables requiring flame retardancy, insulation protection of various busbars, and corrosion and wear resistance of various pipelines.
