Epoxy rod, the full name is Epoxy Fiberglass Rod, also called insulator core rod. It is a high-performance composite rod with glass fiber as reinforced material and epoxy resin as matrix. Manufactured through the pultrusion process, it is an important structural material in the power industry and many industrial fields.
A composite insulator that fails in service rarely fails because the silicone housing was the wrong color. It fails because the fiberglass core inside it was selected, manufactured, or handled without enough attention to the details that actually control mechanical strength and ...

READ MOREAt 6:40 on a weekday morning, the 27.5 kV feeder inside a busy urban tunnel loses insulation. The pantograph drops, the train glides to a halt, and every service behind it stacks up. In most cases the failed component is not the feeder cable or the circuit breaker, but the railw...
READ MOREAn epoxy rod, whose full name is epoxy fiberglass rod and which is also referred to as an insulator core rod, is a high performance composite rod built from glass fiber as the reinforcing material and epoxy resin as the matrix. Manufactured through a pultrusion process, it functions as an important structural material across the power industry and a number of other industrial fields. Taizhou HuaDong Insulated Material Co., Ltd. produces this rod as part of its FRP rod line, using it as the same fiberglass core that also runs through the composite insulators the company manufactures.
An epoxy rod is a cylindrical rod with a smooth surface and flat end faces, and it comes in several colors that are commonly used to tell grades, batches, or uses apart.
Diameter ranges from millimeters up to more than a hundred millimeters, and length is usually long, with sizes that can be customized to customer requirements.
Parts are processed into shed structures or threaded structures during application to connect with insulating jackets or metal accessories.
Taizhou HuaDong Insulated Material Co., Ltd. controls these same tolerances and material ratios across its epoxy rod output, which is what allows the rod to serve as the internal support of a composite insulator in one project and a precision insulating shaft in another.
This spread of applications is also why Taizhou HuaDong Insulated Material Co., Ltd. positions the epoxy rod as a cross-industry product rather than a single-use component tied only to insulators.
An epoxy rod on its own is a structural and insulating material, and Taizhou HuaDong Insulated Material Co., Ltd. carries it through the rest of the manufacturing chain when a customer needs a finished part. The same rod that leaves the pultrusion line as an epoxy rod becomes the core of a composite insulator once it is combined with a silicone rubber sheath and metal end fittings, which is why the company's FRP rod, composite insulator, and metal end fitting product lines are built around a shared material base rather than sourced separately. Since Taizhou HuaDong Insulated Material Co., Ltd. was founded in October 1994 as Yangzhou Dajieshi FRP Products Co., Ltd, this pairing of rod production with finished insulator assembly has remained the core of the business, with output reaching customers across North and South America, Africa, Asia, and Europe, including the USA, Kenya, Korea, India, Vietnam, Iran, Russia, Germany, and Romania.
Yes, epoxy rod is the full commercial name for epoxy fiberglass rod, and it is also referred to as an insulator core rod.
Fiber content exceeds 80 percent of the composite, with glass fiber acting as the main load bearing phase and epoxy resin serving as the bonding and protective matrix.
Epoxy rods are available in colors such as green, yellow, white, and gray, which are often used to distinguish different grades, batches, or uses.
Epoxy rod is manufactured through a pultrusion process that combines glass fiber reinforcement with an epoxy resin matrix.
Yes, diameters range from millimeters up to more than a hundred millimeters, lengths are usually long, and sizing can be customized to customer requirements.
Yes, beyond composite insulators and high voltage fuses, epoxy rod is used in aerospace structural parts, chemical equipment such as pipes and brackets, rail transit components, and insulated shafts and support arms in precision machinery.
