Like its name, it is designed and developed for electrical polymeric insulators. Polymeric insulator (with another name composite insulator) is made of fiber glass core in the rod shape and covered by polymer, which are called “polymer housing”. For a good polymeric insulator with sound quality, the polymer housing shall fit the surface of rod tightly, no gap or crack shall be found in the binding face. To meet this demand, a extremely vital process during the production is called “rod sanding”. It is to grind the surface of fiber glass rod and make that smooth surface of fiber glass core tough so that friction force and contact area shall increase and bind agent will better attach to it. Related tests see: boiling test for electrical insulator on overhead line WHY SHOULD USE THIS “INSUALTOR ROD SANDING MACHINE”? This rod sanding equipment has much higher efficiency in mass insulator production. It is powered by electrical motor and grinds the fiber glass rod rapidly with constant speed and force, which ensure that all the rod will be grinded as same. The limit of tolerance will be controlled in a very small range which is regarded as effective control of

The diameter of the rod can vary in a large range. Besides, this “rod sanding machine” manufactured by us is improved and optimized in structure and functions according to problems raised by...
