Recently, our company completed an international order and shipped a batch of PETV-2 class B enameled wrapped copper type size 0.23 mm². This lot will be used in vacuum pumps.
Product parameters
The enamel is typically a polymer film that provides a tough continuous layer of insulation. Resins used in the development of enamels are designed with wire properties in mind like abrasion resistance, solderability, and thermal rating. Enameled wires are engineered to meet temperature classes from 105 to 240°C guaranteeing service life at rated temperature for 20,000 hours. Its parameters are as follows:

country introduction
The Czech Republic was originally an industrial area of the Austro-Hungarian Empire, where 70% of the industry was concentrated. It is mainly engaged in machinery manufacturing, various machine tools, power equipment, ships, automobiles, electric locomotives, steel rolling equipment, military industry, and light textile, and the chemical and glass industries are also relatively developed. Weaving, shoemaking and beer brewing are all famous in the world. The industrial base is thick. After World War II, the original industrial structure was changed, focusing on the development of steel and heavy machinery industries. Industry accounted for 40% of the GDP (1999).
The major Czech industries include machinery, chemicals, metallurgy, textiles, electricity, food, shoemaking, wood processing and glass manufacturing.
application
A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space.
According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas capture pumps and gas transfer pumps. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries.
With the development of vacuum applications, there are many kinds of vacuum pumps, whose pumping speed ranges from a few tenths of a liter per second to hundreds of thousands or millions of liters per second. As vacuum technology has wider and wider requirements for its application pressure range in the field of production and scientific research, most of them need to be composed of several vacuum pumps to form a vacuum pumping system to pump air together to meet the requirements of production and scientific research processes. Due to the vacuum The range of working pressure involved in the application department is very wide, so it is impossible for any type of vacuum pump to be completely suitable for all working pressure ranges. Different types of vacuum pumps can only be used according to different working pressure ranges and different working requirements. . For the convenience of use and the needs of various vacuum processes, sometimes various vacuum pumps are combined according to their performance requirements and applied in unit type.
