Surge Arresters
Surge Arresters
Zinc-oxide surge arresters protecting the transformer systems from high lightning impulses and switching overvoltage surges.
Priced per requirement — tell us grade, width, thickness and quantity and we quote against it.
Technical specifications
| Scope | Bought-in components supplied alongside the insulation package |
|---|---|
| Selection | Specified against the transformer rating, duty and applicable standard |
| Documentation | Manufacturer certification supplied with each item |
| Form | Supplied as part of a consolidated shipment |
| 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
Zinc-oxide surge arresters protecting the transformer systems from high lightning impulses and switching overvoltage surges.
A technical guide to matching high-performance insulation grades with specific transformer profiles.
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
New build
Supplied alongside the insulation package so one order covers the bill of materials.
Overhaul
Replacement fittings specified against the original rating and standard.
Consolidation
Shipped with the rest of the order rather than chased from separate suppliers.
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
Can these ship with the insulation order?
Yes. Consolidating them into one purchase order and one shipment is the point of supplying them.
How is the right item selected?
Against the transformer rating, duty and the applicable standard. Send the specification and we will come back with what fits.
What certification is supplied?
The manufacturer's certification for each item, with the shipment.
Datasheet
Full property tables, test methods and tolerances for Surge Arresters are on the datasheet. Request it and we will send the current revision.
Next step
