Utilization in electrotechnical industry of fasteners based on insulating threaded rods

The electrical industry uses more and more threaded rods based on insulating materials as fasteners. The threaded rods here described are machined from laminates based on epoxy resin and glass fibre reinforcement. After a short theoretical consideration, an explanation is given on the choice of the type of reinforcement. Tests are described and discussion of the results follows, before a conclusion about the possible improvements to that sort of product.
