What are Polycast retrofit solutions for electrical systems?

Polycast specializes in reverse engineering and manufacturing replacement parts for obsolete or unique electrical insulating products. We provide high-quality epoxy equivalents for bushings, current transformers (CTs), and insulators from manufacturers like ABB, GE, Westinghouse, and others.

What is required for a Polycast retrofit?

A sketch, photo, drawing, or physical part—we reverse engineer and manufacture epoxy replacements to your specifications.

Why choose epoxy replacements over original porcelain or polymer components?

Our form-fit-function epoxy replacements preserve critical electrical clearances and dielectric performance while offering better durability and availability. They allow utilities and OEMs to maintain legacy assets without the need for expensive redesigns or full equipment replacements.

Which legacy brands can Polycast provide retrofit parts for?

We have an extensive catalogue of replacements for leading and niche manufacturers, including EPC, ABB, Westinghouse, GE, Lapp, Ohio Brass, and many others.

Q: Can Polycast create a retrofit solution if the original part is not in your catalogue?

Yes. While we have hundreds of end-of-line standard items, our engineering team can develop custom retrofit solutions when no direct replacement exists, ensuring your legacy power distribution equipment remains operational.

What We Do

Retrofit

Polycast has reverse engineered and manufactured a wide array of replacement and retrofit parts for obsolete and unique electrical insulating products. We specialize in engineering and casting high‑quality epoxy equivalents for obsolete and long lead‑time bushings, current transformers (CTs) and insulators from manufacturers such as EPC, ABB, Westinghouse, GE, Lapp, and Ohio Brass.

These epoxy insulating components are used in medium‑voltage switchgear, substations, transformers, and related power distribution equipment, allowing utilities, OEMs, and service providers to maintain legacy assets without redesigning or replacing entire assemblies. Typical retrofit projects involve form‑fit‑function epoxy replacements for original porcelain or polymer bushings, CTs and standoff / bus support insulators, preserving critical electrical clearances and dielectric performance while improving long‑term availability of spare parts.

Retrofit solutions help reduce lead times, mitigate obsolescence risk, and avoid costly equipment changes by providing drop‑in compatible components that integrate with existing hardware and mounting footprints. Our catalogue includes hundreds of end‑of‑line standard items from leading and niche manufacturers, and our engineering team can also develop custom retrofit solutions when no direct replacement exists.
