Product Description

Nomex, also known as aramid 1313 in China, is an excellent high-temperature and flame-retardant fiber invented and put into use by DuPont in the 1960s. It can maintain about 80% of its original strength at 200 ºC, and can still maintain 65% -70% of its original strength after 100 hours of continuous use at 260 ºC. It forms a barrier between the human body and clothing, reduces heat transfer efficiency, and provides protection against most acids, The stability of alkali is also very good. Due to its outstanding performance and broad market prospects, various countries have conducted research and development on its heat resistance and electrical performance, which are both outstanding. It is widely used in military and electrical industries and is an excellent insulation material in the H-class.

Enhancing Transformer Function to Improve Motor Life and Reliability
NOMEX; The product can have various applications in various types of transformers (including open ventilation dry-type, cast coil type, and liquid filled type): wire winding, layer insulation, segmented and box insulation, winding end filling, partition and bar, etc. In open ventilated dry type (OVDT) transformers, NOMEX ® The product can greatly improve the design of such transformers, reduce electrical losses, improve backup capacity, increase safety and reliability, and reduce the amount of steel used in conductors and iron cores, thereby reducing size and cost. A major advantage of dry-type transformers is that they can be placed inside buildings.
NOMEX ® The product can also improve the performance of liquid filled transformers and reduce the frequency of maintenance. NOMEX ® The universality and singularity of products can help reduce inventory and costs.
NOMEX ® The product is widely used in electric motors and generators, for slot wedge insulation, phase insulation, end laminated plates, etc. To improve the insulation, mechanical properties, safety, and service life of various rotating equipment (such as AC and DC motors, random coils and model coils, and even large steam turbine generators).

Brief introduction:
What is kevlar twisted yarn?
Kevlar twisted yarn has extremely high tensile strength, exceeding 28 grams per denier, which is 5-6 times that of high-quality steel, with a modulus 2-3 times that of steel or fiberglass, toughness twice that of steel, and weight only 1/5 of steel. The strength and toughness of aramid 1414 also make it extremely difficult to cut and process, requiring expensive specialized tools.
Aramid 1414 has a wide range of continuous use temperatures, allowing for long-term normal operation within the range of -196 ºC to 330 ºC. The shrinkage rate at 150 ºC is 0, and it does not decompose or melt at high temperatures of 560 ºC. Its heat resistance is superior to that of aramid 1313, and it has good insulation and corrosion resistance, with a long life cycle, earning it the reputation of "synthetic steel wire".


Mechanical properties of Kevlar twisted yarn
The strength is 3.6Gpa, the elongation modulus is 131Gpa, and the elongation at break is 2.8% -3.5%. It has extremely high strength, with a weight to weight ratio of 5-6 times that of steel wire, a modulus of 2-3 times that of steel wire or fiberglass, and 7 times that of high-strength nylon. It is recognized as one of the world's sewing threads.

Thermal properties of Kevlar twisted yarn
Long term use temperature: 380 ºC
Axial thermal expansion coefficient: -2 × 10 ^ (-6)/K
Thermal conductivity: 0.048 W (m · K)
It has high stability in temperature performance, not only able to be used for a long time in the temperature range of -196 ºC to 380 ºC without significant changes or losses, but also has non solubility, non combustion (fire resistance), and will only start carbonization at 427 ºC. Even at a low temperature of -196 ºC, it will not become brittle or suffer performance losses. It can also withstand temperature resistance up to 585 ºC for short periods of contact.
