Insulating rings are used to electrically isolate a conductor or component from a surrounding conductor or ground. They are often made of materials with high electrical resistance, such as plastic or ceramic, and are used in a variety of electrical and electronic applications.
Insulating rings are commonly used to provide electrical insulation between conductors in electrical equipment, such as transformers, motors, generators, and electrical panels. They can also be used to provide electrical isolation between different parts of a circuit, such as between the windings of a transformer or between the stator and rotor of a motor.
In addition to providing electrical insulation, insulating rings can also serve other purposes, such as mechanically supporting or spacing components within an electrical assembly, or protecting components from mechanical damage.
There are many different types of insulating rings available, including solid, split, and tapered designs, and they can be made from a variety of materials, including plastic, ceramic, and fiberglass. The type of insulating ring used in a particular application depends on the specific requirements of the application, such as the voltage and current levels, the operating temperature, and the mechanical and environmental conditions.
