NOVELTY - Polyimide-inorganic fiber cross-linked coupling insulating pull rod, which is formed by compounding epoxy resin and fiber fabric layer. The fiber fabric is 10-15 layers of polyimide-inorganic fiber coupled cross-linked tubes stacked. USE - Used as polyimide-inorganic fiber cross-linked coupling insulating pull rod. ADVANTAGE - The rod: has excellent interface performance, mechanical performance and insulation performance, excellent heat resistance and radiation resistance and reduces the maintenance frequency and maintenance cost of the corresponding high voltage switch device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparing polyimide-inorganic fiber cross-linked coupling insulating pull rod comprising preparing polyimide fiber yarn, placing the polyimide fiber yarn inorganic fiber cross-linking coupling tube on the mandrel in sequence to obtain the fiber fabric layer, placing the fiber fabric layer in the mold, injecting epoxy resin, demolding after curing to obtain the polyimide pull rod of the inorganic fiber mixing pipe after curing.
