FAQs

Your questions answered

What types of ceramic insulators do you supply?

The range covers electrical insulator tubes (single, twin, multi-bore), fish spine beads, ignition tubes, lead-through tubes for furnace passages, and custom insulator components.

Which material has the best dielectric properties?

High-purity alumina offers high dielectric strength with strong high-temperature performance. Boron nitride provides exceptional electrical insulation in extreme high-temperature service. Steatite is well-suited to general industrial electrical applications.

Can you supply glazed ignition tubes?

Yes. Ignition tubes are supplied straight or shaped, glazed or unglazed, and as components or pre-assembled units to suit your ignition system.
