EV & ESS Insulation Components

We can quote the set or any single part in it. What we prefer is to see the pack drawing or the current bill of materials, even when you only need one item, because the wall on a sleeve and the thickness of a spacer are decided by the same tolerance stack. Quoting one part in isolation is how you end up with an assembly that does not fit.

No, and we will say so at quotation. The 800 V version needs the recovered wall, the joint treatment and the tracking resistance reviewed again. We will tell you which parts carry over unchanged and which ones move to a heavier schedule, so your qualification plan only re-tests what actually changed.

UL 94 V-0 is available across the standard grades in the families we use for packs and racks, with the certificate per batch. If your programme needs a specific declaration format or a substance list, send it at enquiry stage rather than after the sample, because the declaration route sometimes changes the grade we would have chosen.

The material is selected against the fluid, not against the temperature alone. Some grades that hold their dielectric strength in dry air lose it after immersion, and a few swell enough to change the fit. Tell us the fluid by name and whether the part sits in splash or full immersion, and we will choose on that basis.

It depends on the process and the dimension. Wound and moulded parts hold different windows than machined ones, and a bore tolerance is more expensive than an OD tolerance on the same part. We quote the window the drawing asks for, and if something on the print will not hold at the price point you are working to, we raise it at quotation.

Yes. Material COA traceable to the incoming certificate, first-article inspection per your plan, in-process dimensional records at each station and final inspection reports. On automotive and ESS programmes we work to IATF 16949 style PPAP expectations, and we will tell you early if a feature cannot be gaged the way your plan describes.

Either works. A PDF drawing with the critical dimensions marked is enough to quote and to build from. A STEP file helps when the part has a feature the print does not fully define, such as a blend at a mounting boss. If the print and the model disagree, we ask before quoting rather than after.

Prototype quantities of a wound or sleeved part are usually days rather than weeks. Parts that need tooling, a composite build or an arc-facing liner take longer, because the drawing goes through engineering review first. Sending the duty along with the drawing is what keeps that review short.

It depends on whether the size is stock or made to drawing. Standard bores ship in sample quantities. Custom tooling, special laminates and wound parts carry a minimum tied to setup, and we state it at quotation rather than after the sample is approved.

Yes, and it is a common request. Send the drawing or a sample plus the duty. One caution: if we only have a sample we can measure what exists, not what the assembly needs, so for anything where a tolerance matters we will ask for the drawing as well.

Yes, across the standard grades in these families, with certificates per batch. If your programme needs a specific declaration format or a named substance list, tell us when you enquire so the correct grade is selected from the start.

Then we tell you, and point at the right family or the right process even when it is not ours. High-voltage duties that genuinely need ceramic, or applications where a standard commercial part is the correct answer, are both cases where saying no costs us one order and saves you a field failure.
