Fiberglass Dog Bone

Fiberglass Dog Bone

A fiberglass dog bone refers to a specific profile or form utilized within the manufacturing and construction sectors. Common applications include transformer core winding and serving as insulating supports within high-voltage products, including dry-type transformers, reactors, high-voltage inverter power modules, power capacitors, and disconnectors. Constructed from composite materials, predominantly reinforced by fiberglass, these dog bones exhibit notable mechanical strength, minimal partial discharge, low dielectric loss, as well as superior resistance to high temperatures and aging.
