Machined parts

Our insulation components are made of epoxy, polyester or phenolic resins and are capable of withstanding high voltages, high temperatures and mechanical stress.

Applications

• Manufacturing electrical insulation components of all shapes and sizes; e.g., for high voltage circuit breakers, switchgear, power conversion and transformers and, but also railway and aerospace
• Laminate components for industrial applications in small and medium-size batches for which automated manufacturing using injection molding systems is not a suitable solution
• Re-fabrication of critical insulation components in case they are not longer available in the marketplace

The manufacturing technologies that we have are:

• Various CNC-machines (up to 5 axis)
• Various presses for plate and shaped profile manufacturing
• Various presses for compression molding
• Filament winding (diameter up to 0.76 m, width up to 2 m)
• Vacuum infusion / RTM equipment
• Saws and grinding machines
• Adhesive bonding equipment
• Coating equipment

Why Hitachi Energy?

• First choice for repair and maintenance parts made out of fiber reinforced composites
• We offer short delivery times with express delivery in case required as we machine laminates and shaped parts in our own factory
• Wide range of raw materials on stock
• Highest precision for accurate and easy assembly of parts
• Deformation-free insulation materials with superior electrical, dielectric, tracking-resistant and thermal properties, odorless and highly resistant to solvents
• Proximity to Hitachi Energy's research center and universities guarantees access to latest technology and material
• Entire manufacturing sequence for assemblies, from procurement of raw materials for construction of jigs and fixtures to fabrication, assembly and logistics

Specification

Laminate materials are available in accordance to common standards as DIN EN IEC 60893, the former DIN 7735, and NEMA for example:

Besides glass fiber, we can machine polyester fiber and aramid fiber parts as well.  

Rods and tubes are available in accordance to common standards as DIN EN IEC 60893, the former DIN 7735, and NEMA for example:

Tubes and Rods

• EP GC 22 / Hgw 38
• GFK 201
