Utility Composite Insulators Industry News

• In August 2024, Gowin Precision Machinery Co., Ltd, a China-based company in rubber molding machinery manufacturing, launched its polymer insulator manufacturing machine as their latest product. The new unit is expected to lower the lead time for the manufacture of polymer insulators while increasing the precision and efficiency of the processes employed. The evolution in the design and development of the cutting-edge machine designed for the needs of the polymer insulator industry can be attributed to the company’s extensive experience in rubber injection molding machines.
   
• In October 2023, CBM added its new PLP silicone insulator line and has finished developing the polymer line post insulator line of products, therefore extending the IP-51-4F line post insulator range with model IP-51-4F as well. These new insulators are designed to replace porcelain or composite insulators and have been fully compliant with ANSI C29.7 and C29.18 standards. The PLP insulators are made entirely in the USA, in Rogers, Arkansas, are lightweight, and impact resistant. The designs of the insulator necks fit very well with the PLP ties ensuring functionality and compatibility.
