FRP sanding machine of composite insulator

THE INSULATOR ROD SANDING MACHINE

(FRP SANDING EUQIPMENT FOR PRODUCTION OF INSULATORS)

GENERAL INTRODUCTION
Like its name, insulator rod sanding/grinding machine is designed and developed for electrical polymeric long rod insulators and pin type insulators. These 2 types of electrical polymeric insulator (with another name composite insulator) is made of  a 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 grinding”. 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.

WHY SHOULD USE THIS “INSULATOR ROD GRINDING/SANDING MACHINE”?
Since we now know that rod grinding process is necessary during insulator production, why would we choose to use this grinding equipment instead of just grind the rod manually?
This rod grinding 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 sanded as same. The limit of tolerance will be controlled in a very small range which is regarded as effective control of quality.

This rod grinding equipment is available for several types of composite insulators: long rod insulator (known as suspension insulator, tension insulator, dead-end insulator), pin type insulator and several post type insulators. The diameter of the rod can vary in a large range.

Besides, this “FRP rod sanding machine” manufactured by us Contune International Co ltd is improved and optimized in structure and functions according to problems raised by insulator manufacturers during the production, in order to ensure that the rod grinder can be easily installed and operated. Easy maintenance is also its pros.
