Electrical insulating materials are defined as materials which offer a very large resistance to flow of current.
Electrical insulation materials classification.
The electrical insulation system for wires used in generators electric motors transformers and other wire wound electrical components is divided into different classes by temperature and temperature rise.
Classification according to substances and materials.
The electrical insulation system is sometimes referred to as insulation class or thermal classification the different classes are defined by nema underwriters laboratories ul and iec.
The insulating materials can be classified in the following two ways.
Overview for electrical insulation materials market helps in providing scope and definitions key findings growth drivers and various dynamics.
The electrical insulation system is sometimes referred to as insulation class or thermal classification.
For electrical and electronic system protection electrical insulation plays the most important role as a protector.
The electrical insulation system for wires used in generators electric motors transformers and other wire wound electrical components is divided into different classes by temperature and temperature rise.
An electrical insulating material insulating material is used to obstruct the flow of current.
Class b insulation consists of materials or combinations of materials such as mica glass fibre asbestos etc with suitable bonding impregnating or coating substances beware a few older applications used asbestos.
Especially for an electrical conductor grounded system electrical machines like a transformer motor and generator and other electric appliances.
But it can be used in equipments with low temperature limits.
Insulation is provided for safety purposes.
There are different types of electrical insulation which are made of different.
Classification of insulating materials.
The global electrical insulation materials market report is a comprehensive research that focuses on the overall consumption structure development trends sales models and sales of top countries in the global electrical insulation.
Based on properties and area of applications electrical engineering materials can be classified as below conductors semiconductors insulators magnetic material a classification chart of electrical engineering materials is shown in figure below conductorsconductors are the materials.
It forms ionic bonds and the materials that have low conductivity and high resistivity are available in the form of solid liquid gaseous like the plastic used for plugs insulating oil used in transformer etc these materials have very high resistance so the flow of electric current requires an.
Other materials or combination of materials not necessarily inorganic may be included in this class if by experience or tests they can be shown to be capable of.
Some materials such as glass paper and teflon which have high resistivity are very good electrical insulators.
These classes cover the insulating materials generally used in electrical machinery based on their thermal stabilty.
