What Is an Insulated Bolt?
An insulated bolt is a bolt that is either covered with or made from an insulating material. These bolts are typically used when electrical isolation is necessary. The insulating materials, such as plastic or rubber, prevent the passage of electricity and help avoid electrical shorts and circuit breakdowns. Insulated bolts made entirely of plastic also resist various chemicals and solutions, offering durability in corrosive environments and chemical processes.
Uses of Insulated Bolts
Insulated bolts find applications in:
1. Electrical Wiring
Used in electrical wiring for insulation between streetcars and overhead wires, or in electrical equipment like switchboards and control panels.
2. Chemical Plants
Utilized in chemical plants to prevent dissimilar metal corrosion, especially in flange connections between iron and SUS pipes.
3. Metal Electrolysis Plants
Widely used in metal electrolysis plants for safely handling metal plates with voltage, preventing sparking and electrical corrosion.
4. Electroplating Factories
Employed in electroplating factories for insulation of metal components and lifting jigs during the plating process.
Principle of Insulated Bolt
The core principle of an Insulated Bolt lies in the electrical insulating properties of its material. The non-conductive nature of materials like plastic or rubber provides effective electrical insulation, preventing current flow and electrical shorts.
Types of Insulated Bolts
Insulated bolts vary based on the type of insulating material used:
1. Plastic-Coated Bolt
A metal bolt with a plastic coating, commonly used for its insulating properties.
2. Rubber-Coated Bolt
A metal bolt coated with rubber, enhancing chemical and abrasion resistance while providing insulation.
3. Ceramic Coated Bolts
A metal bolt with a ceramic coating, suitable for high-temperature and high-voltage environments, often used in power transmission and high-voltage equipment.
