Electric Insulators Industry News

• In May 2024, LAPP Insulators showcased their products at the IEEE PES T&D exhibition in Anaheim. The event drew over 10,000 industry professionals worldwide. The company highlighted their porcelain insulators, emphasizing their durability and eco-friendly qualities. These products support the circular economy and meet power industry needs. LAPP Insulators plans to use feedback from the event to improve their offerings and looks forward to future IEEE exhibitions.
   
• In February 2023, Mar-Bal, Inc. has launched new Slim Line insulators for low and medium voltage uses. These insulators are smaller but keep the same electrical properties, making them good for tight spaces. They can often replace porcelain and epoxy types in medium and high voltage settings. Mar-Bal plans to offer all sizes in the NEMA line, which should help with the long wait times often seen with porcelain and ceramic insulators.
