Vulcanized fiber tubing, also spelled vulcanised fibre tubing, is a dense, rigid insulating material with good physical and mechanical properties, dielectric strength, arc resistance, and arc-quenching behavior. It has been a standard choice for fuse tubes and high-voltage cutout liners for decades, and it is still the reference material that […]

Epoxy glass fiber wound pipe and epoxy glass canvas (cloth) tube are both epoxy fiberglass insulators, but the construction method and properties differ. This article compares them across the properties that decide a specification, so you can choose the right tube for electronics, electrical, or mechanical duty. How the Two […]

The shift to electrified vehicles is expanding the fuse market, but it is also making fuse application harder. Higher voltages, faster charging, and tighter system integration are pushing fuses past the limits of existing standards and component-only thinking. This guide covers the challenges EV and HEV fuse buyers should plan […]

Fuses are grouped by the voltage they protect and by what they protect. High-voltage and low-voltage fuses differ not just in rating but in how the arc is contained and interrupted. Understanding the structure behind each type helps you specify the right insulating tube, because the same fault that a […]

Engineers ask how many types of fuses there are because the answer decides everything downstream: the interrupting rating you write on a datasheet, the speed class you specify, and the fuse tube you end up buying. There is no single number. In practice fuses are grouped along five axes, and […]

For cutout fuse construction, two tube designs are common: the moisture-proof fuse tube and the horn fiber fuse tube. Each suits a different current class and environment, and choosing the right one reduces liner expansion that can cause interruption problems. Two Tube Types, Two Duties Moisture-proof fuse tube: standard on […]

Covering a vulcanized fiber tube with a fiberglass and epoxy canvas layer combines the arc-quenching behavior of the fiber core with the strength and water resistance of the outer composite. This article explains the properties that make the combination useful and where it fits. Why Combine a Fiber Core With […]

Hard fiber tubes are used in both fuse and motor applications, but “hard fiber” covers several materials. Understanding the four common types, and what each is good for, helps you specify the right tube and avoid a mismatch that shows up as a failed fuse or a short-lived motor part. […]

G5 and G9 melamine tubes are produced by lamination molding and tube rolling. Understanding the process explains why melamine tube behaves the way it does, why inner diameter affects the maximum producible length, and which of the two methods suits your part. This page covers both production routes and the […]
