NEMA Laminated & china’model insulate sheet IEC Laminated products model description
1、The phenolic paper laminate of 3020
This model product actually has two standards, one of which is JB/T8149.1-2000, and the other is GB1302–77, that is, the new standard and the old standard, according to the national regulations once the new standard is issued, the old standard is null and void, but the old standard has been implemented for many years, and the user has not yet seen the new standard before, the continuation of the order called 3020 is purely the old standard, at this time Should focus on the introduction of the new standard 3020, in order to achieve the purpose of gradual promotion.
1-1, China’s new standard 3020 phenolic paper laminate
This product is non-equivalent to the use of IEC60893-3-4PFCP202 standard recommended standard products in the machinery industry, in the normal state with good electrical properties, suitable for work in the industrial frequency and high pressure, high electrical strength in oil, good electrical strength under normal humidity, parallel layer to the breakdown voltage (in the experiment before the air treatment at 105 degrees for 96 hours) for 35KV, is a high electrical performance cardboard, equivalent to U.S. NEMA standard XX grade, must be produced using new technology, the price is higher than the old standard 3020.
1-2, China’s old standard 3020 phenolic paper laminate
It belongs to the former Soviet Union A (sound: ah) type cardboard, compared with the old standard 3021 model electrical performance is higher, used for the high requirements of dielectric properties of the motor, electrical equipment for insulation parts, can be used in the transformer oil. Its 90 degrees in oil parallel layer to the voltage resistance, 5 minutes for 8KV, compared with the new standard 3020, a lot lower, simple process, lower prices.
Most of the old customers for many years to use the old standard 3020, although the electrical performance is lower, but has adapted, indicating that its adoption of the new standard 3020 because of the high price there is a certain degree of difficulty, so the old standard 3020 actually has a certain degree of vitality.
2、3021 phenolic paper laminate
This model is roughly the same as 3020 products, also has two sets of standards. One of them is 8149.1-2000, and the other is GB1302-77, that is, the new and old two standards.
2-1 New standard 3021 phenolic paper laminate
This product is non-equivalent to IEC60893-3-4, PFCP203 standard machinery industry recommended standard products, mechanical and electrical, good electrical performance under normal humidity, also suitable for hot punching process, its resistance after water infiltration is ≥ 1.0 * 107, than PFCP203 ≥ 5.0 * 107, but there is still a high level, the general old process is difficult to achieve, so we must use new technology The new process can be produced, so the cost is higher.
2-2 Old standard 3021 phenolic paper laminate
belong to the former Soviet Union B (sound: grip) type cardboard, for general purpose cardboard, suitable for the mechanical properties of higher requirements of the motor, electrical equipment for insulation structure parts, can be used in the transformer oil, electrical insulation performance in the humid air is poor, in order to use the surface of its processing parts in the South often need to invade the glue, that is, gum wood treatment, its thin plate must be heated before punching out the shape of the simpler processing parts, so Poor labor environment and waste of energy, previously exported by a small number of foreign countries instead of wood, do play cement box use, China in the 20th century, basically only this kind of cardboard, for the user to bring great inconvenience.
To 3021 type products should take the initiative to introduce the advantages of the new standard products, no need to glue wood processing, thin board punching processability, especially for the former Soviet Union users to explain the Soviet Union B (grip) type board has been effectively improved, its electrical properties have been substantially improved, the product toughness to improve the brittleness is lower, the use of a wider range.
3、PFCP202 phenolic paper laminate
This model is the international standard IEC893-3-4 (1993) products, this standard is adopted by the new domestic line standard 3020 products, but in the main performance downward adjustment, such as parallel layer to the electrical strength from 60KV to 35KV, not easy to be recognized by users in some countries, this practice is conducive to the promotion of other countries, the quality is higher than 3020, the price also increased accordingly.
4、PFCP203 phenolic paper laminate
This model is also the product of international standard IEC892-3-4 (1993). When this standard is quoted by Chinese line standard, the insulation resistance after water intrusion is changed from 5.0107 to 1.0107, which is difficult to be accepted by users in some countries, so this product directly adopts IEC standard.
5、PFCP206 and PFCP308 phenolic paper laminate
These two models for IEC893-3-4 products, mechanical and electrical use, good electrical properties under high humidity, also suitable for hot punching process, after invasion of water insulation resistance up to 1.0 * 109, parallel layer to voltage (90 degrees in oil) up to 25KV for the characteristics of this product, PFCP308 has a good flame retardant, its electrical properties and comparable to 3240, from this perspective in some products It can replace the use of glass cloth board.
These two types of cardboard are mainly marketed to users in Asian and European countries.
6、PFCP207 phenolic paper laminate
This type of product belongs to IEC893-3-4 (1993) products, wellele maximum thickness of 2.0mm, with low mechanical properties, the thickness of 0.8mm or less can be room temperature punching and shearing, thicker should be heated to 70-90 degrees after punching and shearing, not only can improve the quality of punching parts, but also can extend the service life of the mold. Mainly available for making electronic products parts, not suitable for other aspects of use. Specifications larger than 2.0mm suggest customers to choose from the following products.
7、PFCP201 F820 F820-1 F820-2 F820-3B F821 F826-1 F826-6 F826-7 phenolic paper laminate, PFCP201 is IEC893-3-4 (1993) product, other models are enterprise standard Q/TXXFR001-2004 products.
This type of products are mechanical, high mechanical strength, good processability, in the PCB industry circuit board testing and other electronic industry usage, not recommended for electrical products, such as special requirements in the contract can also be used in some electrical products, F826-1 F826-6 F826-7 has a high degree of straightness, thickness tolerance requirements, and a certain Shore hardness.
8、3021B 3021C phenolic paper laminate
It is used for general products with low requirements on mechanical and electrical properties, short life expectancy and uncomplicated processing. The product standard number is O/TXXFR001-2004.
9、F825 series phenolic paper laminate
This series of products is the enterprise standard (draft) products, need further development and verification, for the models that have been close to success can receive a small number of trial orders, the gap is larger, the technical requirements as the goal, efforts to research and test development, and strive to complete product development work as soon as possible.
