Nomex® Angle Rings

Nomex® Angle Rings

Molded aramid components for high-temperature hybrid transformers. Capable of continuous operation up to 220°C.

Priced per requirement — tell us grade, width, thickness and quantity and we quote against it.

Technical specifications

Composition

Moulded, drawn or pressed from transformerboard; aramid where the class demands it

Standard

Made to customer drawing; base material to IEC 60641

Thermal class

As the base board: Class A in oil, aramid grades to 220 °C

Manufacture

Machine-moulded, hand-moulded, drawn or pressed depending on geometry

Tolerances

To drawing; agreed before first article

Form

Finished components, supplied dried and packed for winding

Compliance

RoHS, REACH; mill test certificate with every consignment

Typical values for this material class, given as a guide. The datasheet carries the property table, test methods and tolerances for the grade and is the governing document.

Overview

Molded aramid components for high-temperature hybrid transformers. Capable of continuous operation up to 220°C.

Sizes, packing and supply

Supplied to your specification — grade, thickness, width and quantity, cut and slit to your dimensions rather than sold from fixed stock sizes. Mill test certificate and certificate of conformity accompany every shipment.

Standards and compliance

  • Manufactured to IEC 60641 / IEC 60554 where the grade is covered
  • Mill test certificate and certificate of conformity with every consignment
  • RoHS and REACH declarations on request

Third-party testing can be arranged where a specification demands independent verification.

Applications

End insulation

Angle rings, caps and end rings shaping the field at the ends of the winding.

Winding support

Cylinders, spacers and clamping rings holding the coil in position under short-circuit force.

Lead management

Snouts, tubes and lead exit systems taking connections out through the barrier system.

Assembly

Washers, fixation elements and edge protection used through the build.

Quality and inspection

Every consignment is inspected before shipment and supplied with its mill certificate. For repeat programmes we hold the approved specification on file, so a reorder repeats a known outcome rather than reopening the conversation.

Frequently asked questions

Do you make parts to our drawing?

Yes — that is most of what this range is. Send the drawing or a sample and we will quote tooling and parts separately so you can see what each costs.

Machine-moulded or hand-moulded?

Machine-moulded suits standard geometry in repeat quantities. Hand-moulded is for shapes and sizes outside the tooling, usually on larger units or one-offs. We will tell you which your part falls into.

What tolerances can you hold?

To the drawing, agreed before the first article. Where a tolerance is tighter than the process holds, we say so at quotation rather than at delivery.

Are aramid versions available?

Yes, for Class F and Class H systems. The same components are made in aramid where the temperature demands it.

Datasheet

Full property tables, test methods and tolerances for Nomex® Angle Rings are on the datasheet. Request it and we will send the current revision.

Next step

Tell us the size and quantity

Send the thickness, slit width and annual volume for https://transformerinsulation.com/wp-content/themes/transformerinsulation and we come back with a costed offer, a firm lead time and the mill certificate you will receive with it.

Tell us the size and quantity

Tell us the grade, thickness, width and quantity. We come back with a costed offer and the datasheet, and say plainly if anything will not work.

We reply the same working day. Your details are used to answer this enquiry and nothing else.
