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 […]

A fusible link is a short piece of insulated low-voltage cable within an automotive wiring harness, designed to protect the harness where a conventional fuse is unsuitable. This article explains what a fusible link is, how it is applied, and how it is sized and coordinated with the other overcurrent […]

Selecting a high-voltage fuse for an electric vehicle or hybrid platform is a different exercise from picking an industrial fuse off a catalog page. The circuit runs on DC, the load swings with every acceleration and regen event, and the fuse sits next to the most expensive hardware on the […]

An electric vehicle high-voltage fuse protects some of the most expensive components on the platform: the battery, the power electronics, and the contactors. Selecting the right fuse is therefore a core part of drivetrain design, and the standards that govern it are not the same ones that govern an industrial […]

A fuse is the simplest protective device in an electrical system, and still one of the most reliable. It carries normal current indefinitely, then opens the circuit when current rises above a set value for a set time. Because the element melts from its own heat, a fuse needs no […]

Selecting or replacing a fuse in a protection circuit is not simply a matter of matching the amps. The device must suit the system voltage, the installation location, and the load, and a replacement must respect the original ratings. This guide covers the replacement rules, the selection method by system […]

When a fuse element melts, an arc forms at the break. Metal vapor from the melting element intensifies the arc and makes it burn harder, so the design goal is to extinguish it as quickly as possible. Understanding why the arc persists, and what actually puts it out, is the […]

A fuse tube is the housing that carries the fuse element and, in expulsion designs, actively clears the arc. It is an electrical component installed in a circuit to keep operation safe, and its role changes with the application. This article explains what the fuse does, how aging affects it, […]

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 […]

Fuse tube production splits into three voltage classes: high-voltage, medium-voltage, and low-voltage fuse tubes. All of them must have arc-extinguishing characteristics. This article walks through how a vulcanized fiber fuse tube and a melamine tube are made, so you understand what you are buying. The Three Voltage Classes and What […]
