Applications

Application Engineering services provided by The Gund Company allow our customers to rely on our materials knowledge and applications experience to provide engineered composite solutions.

We are specialists in electrical insulation or composite materials. Our technical sales and customer service staff provide our customers with valuable insight on how to improve component designs to increase efficiency and functionality while reducing cost.

We review customer component designs and assembly drawings to seek out cost savings opportunities. Given a customer’s interest in lowering costs by reviewing component and assembly designs, we can prepare a list of potential options for cost savings.

Introduction of New Materials for Specific Application

  • NEMA GPO-3 Grade H950 developed for superior track resistance, allowing phase barriers in some designs to be reduced in thickness from 3/16″ to 1/8″.
  • Tesa 4616 glass cloth tape for dry type transformers eliminates fraying of tape found in industry standard 3M#27.
  • Improved paper phenolic laminate “Arboron” introduced as a track resistant paper phenolic for use as coil supports and low voltage phase barriers.
  • Tesa 51597 introduced after exhaustive testing for use as layer insulating type in transformer coils.

Improvements in Component Applications

Common product design efforts reduce the number of individually designed components, allowing for more standardization across a customer’s product line. Functional Improvements in Component Fabrication

  • Barriers submerged in oil have sawed edges (instead of sheared) to prevent loose glass fibers from circulating within the coil.
  • Fuse boards labeled with hole identification numbers allow ease of assembly for same board across the product line.
  • Component assemblies for individual units prepackaged and labeled for routing directly to assembly – bypassing any receiving inspection.

By having a technical understanding of the equipment that our customers manufacture and repair, The Gund Company can offer our expertise in insulating materials and experience in component applications.
