Epoxy resin pipes are mainly used for secondary protection of low-voltage lines and electrical equipment above the line during power outage maintenance, to prevent induced voltage damage in maintenance lines, and to provide a reliable guarantee for security inspectors.

If the epoxy resin tube adopts untwisted roving/pulling/winding/pulling, the radial strength is obviously too low; if the hoop winding is increased, the wall thickness will be thicker; it will be difficult to perform pultrusion after first pulling and then winding, and the appearance will not be ideal. . Secondly, the hoop bobbins have to be replaced from time to time; adding winding parts will also cost a lot of equipment.

The epoxy resin pipe is made of electrical alkali-free glass fiber cloth impregnated with epoxy resin, baked and processed by hot pressing in a molding die. The cross-section is round. The glass cloth rod has high mechanical properties. Dielectric properties and good machinability. The heat resistance grade can be divided into B grade (130 degrees) F grade (155 degrees) H grade (180 degrees) C grade (above 180 degrees). Epoxy resin pipes are suitable for insulating structural parts in electrical equipment, and can be used in wet environmental conditions and transformer oil.
