Taporel Electrical Insulation Technology Co., Ltd. is a high-tech enterprise dedicated to the research, production, and export of electrical insulation components. Our main products include FRP insulating rods, composite insulators, dog bone spacers, and knock rods, widely applied in power transformers, substations, and electrical systems. Taporel has passed ISO9001, ROHS, and REACH certifications, offering professional OEM/ODM services to clients worldwide.
The dog bone insulating spacer, also known as a "bone-shaped insulator", is designed for dry-type transformers to separate and support coil windings. It is manufactured by pultruding glass fiber reinforced epoxy resin (FRP), offering high insulation, mechanical strength, and resistance to heat and humidity.
Named for its dog bone-like shape, the spacer features:
Raised ends for coil gripping
A narrowed middle for spacing control
Optional surface treatments like sandblasting, moisture-proofing, and mildew resistance
