FRP dog bone
FRP dog bones are a type of fiberglass-reinforced plastic structural support commonly used in dry transformer applications — strong, durable, and sustainable, making them a solid choice across a range of uses.
Guangdong Haikuo has designed and manufactured FRP dog bones for more than 20 years, with a product range built for different applications.
Benefits for Dry Transformer Support
Strength: as strong as steel or concrete supports, but lighter and more flexible — less prone to cracking or breaking under stress.
Durability: corrosion-resistant, a strong fit for harsh environments where steel or concrete supports would weaken and lose lifespan.
Sustainability: FRP dog bones are made from recyclable materials and can be recycled at end of life — unlike steel or concrete, which are non-renewable and can’t be recycled the same way.
Applications
Supporting transformers on concrete pads: distributing weight evenly and preventing sinking into the concrete.
Supporting transformers on steel platforms: protecting the transformer from corrosion and damage.
Supporting transformers on seismically active sites: FRP dog bones‘ flexibility (compared to steel or concrete) helps reduce earthquake damage risk.
Guangdong Haikuo FRP Dog Bones
Our dog bones are built from high-quality materials — E-glass fibers, polyester resins, vinyl ester resins — using manufacturing processes chosen to meet demanding customer requirements. If you need a strong, durable, sustainable FRP dog bone for a dry transformer application, Guangdong Haikuo brings the experience, expertise, and quality commitment to deliver the right product.
A Few More Advantages
FRP dog bones are also less likely to conduct electricity than steel or concrete supports — a safer choice wherever electrical conductivity is a concern — and less likely to produce sparks, adding a fire-safety benefit too.
Conclusion
Overall, FRP dog bones are a versatile, reliable material offering real advantages over traditional steel or concrete supports.
