Talking about mica high temperature line

Mica high temperature wire is suitable for the installation and connection of wires and lines with AC voltage below 750V in high temperature environment. It is widely used in electromagnetic heating coils, metallurgy, petroleum, chemical, oil refining, natural gas and other special environments. In electrical installations and various electric heating equipment, electric heating devices and so on. In view of the wide application of refractory mica wire at home and abroad, today we will briefly talk about this high temperature wire.

Mica high temperature wire is suitable for the installation and connection of wires and lines with AC voltage below 750V in high temperature environment. It is widely used in electromagnetic heating coils, metallurgy, petroleum, chemical, oil refining, natural gas and other special environments. In electrical installations and various electric heating equipment, electric heating devices and so on. In view of the wide application of refractory mica wire at home and abroad, today we will briefly talk about this high temperature wire.
The structure of the refractory mica wire is divided into three layers and four layers. The first is the conductor, then the glass fiber, mica, and glass fiber. The third layer is to remove the middle layer of glass fiber. Of course, there are other requirements. We can produce according to the needs of customers. .
The conductors on the market are mainly bare copper, nickel-plated copper wire and pure nickel wire. In fact, the temperature resistance of bare copper conductors cannot reach the starting point of five hundred degrees of mica high temperature wire, so it has been forgotten by the market recently.
Mica tape is an important element of refractory mica wire. It is mainly divided into natural mica and synthetic mica. There are two kinds of natural mica for wire insulation: muscovite and phlogopite. Phlogopite and synthetic mica are often used for production.
At present, my country has made remarkable achievements in the development and production of refractory synthetic mica tapes. It has excellent fire resistance and is more and more popular in the cable industry. At present, foreign manufacturers have no products superior to this kind of wire. The mica high temperature wire produced by our company has no peeling and cracking at low temperature winding -600C, insulation resistance >400mw/m at high temperature 5000C, withstand voltage 600V, and no breakdown in 120min. We must quickly enter the domestic and international markets and vigorously promote this product.
Welcome customers at home and abroad to come to consult and cooperate!
