How Is Mica Insulation Used in High Voltage Insulation Application?

Mica is preferred over other insulation materials for high voltage insulation in a diverse range of industries for its exceptional physical capabilities. The key properties that make it ideal to use as high voltage insulation are exceptional thermal stability and high dielectric strength. It can withstand up to 2000 kilovolts per mm before breaking down, and pure mica is stable up to the temperature of 900 degrees C, whereas when combined with other materials, it can withstand the temperature up to 1600 C. High thermal stability is essential because high voltage can break the insulation material putting the safety of others at risk.



Here are the three most common uses of mica in high voltage insulation applications:   

Electric vehicles



The electric vehicle manufacturing industry uses mica-based insulation products for the insulation of the high voltage electric batteries and other electrical components to ensure the safety of users against the electric circuits. Mica insulation is used to insulate a range of EV components, including chassis, charging components, and battery compartment, in order to improve the safety of the user and to ensure that vehicles meet vital safety requirements and standards. 

 

High voltage wire insulation 

 

Mica cable tapes are used for the insulation of high voltage wires. High-voltage cables are used for electric power transmission at high voltage in various applications. They need to be fully insulated for safe operations. Mica cable tapes act as insulation.

 

High voltage capacitors

 

High voltage capacitors are also made of the mica material. They provide reliability and stability to a circuit and ensure the circuit is best suited to high-frequency applications and situations and enable high precision performance.

 

So these are the three main high-voltage insulation applications of mica products.

How is Mica Used for Electric Vehicle Battery Insulation?

Image
Electric vehicles are the future. The ban on petrol and diesel vehicles is going to roll out by 2030. Thus, the transition to electric vehicles is inevitable. Electric vehicle technology is still in the early stages and thus expensive.  Apart from making efficient battery systems, manufacturers need to ensure that electric vehicle battery systems are safe. The electric vehicle battery pack needs to be insulated thermally and electrically to ensure safety. In this post, we will look at how mica material is used for electric vehicle battery insulation.   Mica Battery Pack Insulation  Mica battery pack insulation is used as a high-temperature incombustible barrier around battery packs and to electrically insulate the battery pack from other critical components of an electric vehicle. Axim Mica mica car battery pack insulation comes with the UL-94 rating and CE and ROHS certifications. You can partner with Axim Mica to design a customized battery pack insulation. Axim h...

A Short Guide on Two Popular Types of Mica Sheets!

Image
Mica is a naturally occurring material that comes in 37 different varieties.  However, only two forms of mica—phlogopite and muscovite—out of the 37 variants are utilized for industrial insulating purposes. Although they come in sheet form, they must first be transformed into powder before being used to create a variety of mica industrial insulation products. Each of these two forms of mica has characteristics that make them suited for a variety of uses in numerous sectors. Read out the below blog to learn about two popular types of micasheets . Types of Mica sheets   Phlogopite Mica Sheets:   The mica sheets that remain stable up to 900°C are known as phlogopite mica sheets. They come in both flexible and rigid forms. The thermal insulation properties of phlogopite mica sheets are different from muscovite mica sheets. Phlogopite mica, out of all the different types of mica, offers the best thermal insulating properties. There are a variety of colors, i...

What is the role of safety certifications of mica sheets in the industry?

Image
Mica sheets are used in various industries for thermal and electrical insulation applications. They are used at high operating temperatures up to 1600 degree cel sius and in high voltage environments. Therefore, it is very important to ensure that mica sheets are safe for use. That’s where the role of  mica sheets  comes into play. The certifications are gained by rigorously testing the product under controlled conditions. Regarding mica sheets, the UL rating is the global industrial safety standard.  Other region-specific fire resistance classifications, such as BS 479 (class 1) and NBN 21-203 (A1), are also used to approve thermal and electrical insulation products. In this post, we will focus on the UL-rating of mica sheets. What are UL standards for safety? UL is a global safety certification company that certifies a wide range of products used in both industrial and commercial applications. If a product is listed or UL certified, the product is globally accepte...
