Introduction about Insulation Paper Features

Application of insulating paper

Insulating paper is a general term for electrical insulating paper. The insulating materials used for the cable, the coil and other electrical equipment also have their own characteristics in addition to have a good insulating performance and mechanical strength. The products are widely used in electric motors and generators, which are used for wedge insulation, phase insulation, the end portion laminate, etc. The Insulation Paper enables all types of rotating equipment (AC and DC motors, random coil and mold line criterium, as well as large turbo) to have better insulation, better mechanical properties, higher security, and longer life.

Classification of insulation paper:

1. Insulating materials mostly use different types due to the use of physical characteristics, temperature, humidity, resistance to chemical environments, the insulating paper is one of them; from the chemical point of view, Nomex insulation paper is an aromatic polyamide, which collectively is called an aromatic polyamide. We can usually seen NOMEX aromatic polyamide in the place where need electrically insulating. It has a unique and appropriate balance of properties, which has been widely used in transformers, motors, generators and other electrical equipment in order to improve the reliability of the electrical insulation for many years.

2. Insulating paper can use different model specifications depending on the thickness of the insulation, the staff can adjust according to the length in the actual needs.

3. In the premise of the original the insulating paper, divide the insulation tape into various width can effectively control costs, save time and improve efficiency, and reduce a lot of trouble;

4. Insulation paper can effectively guarantee the short fibers and chromatography fiber insulating medium, ash loss performance mix in water-based slurry, and made into a continuous sheet-like structure by specialized manufacturing machine. The density of the paper just out of the machine is lower, having only moderate mechanical and electrical properties.

Characteristics of the insulation paper: 1. High toughness 2. Excellent dielectric properties 3. High thermal conductivity 4. Easily inserted and fitted 5. A certain hardness, and resilience. 6. UL insulation system certification, Level 200 ° C (N) 7. CSA certification, temperature rating of 180 ° C and 2

Factors Affecting the Quality of Cable Accessories

The factors affecting the cable accessories quality are diverse, and there are the following aspects in principle:

First, the electrical performance: The quality of electrical performance is the first principle of judging the quality of cable accessories. We have to mainly consider whether the electric field distribution of cable accessories is reasonable, whether the measures to improve the electric field distribution are appropriate and the electrical strength of the material, dielectric loss and insulation. At the same time, we have to consider the stability of the electrical properties, including the chemistry, physical properties and structure stability of cable accessories materials, such as the cable sleeve, such as whether the stress control material performance is stable, whether the stress cone is easy to deform, the effects caused by the cable insulation retraction of the electric field of cable accessories distribution and preventive measures, the combination of various materials compatibility, stability, etc. and the combination of the performance of the interface. In addition, we should also consider the thermal properties, such as dielectric loss, the conductor connecting the contact resistance of its stability, release of the heat conduction, the thermal expansion and contraction of the influence of the electrical properties and mechanical properties of the various components of cable attachment.

Second, the sealing performance: The seal moisture resistant can directly impact on the performance and service life of electrical cable accessories. A sealing structure of the terminal is reliable and stable. In general, the middle connector should be a matched metal moisture-proof enclosure, buried or used in a wet environment.

Third, the mechanical properties: Terminal should have sufficient ability to resist bending and shock. The middle joints (power supply cable sleeving) should be able to withstand a certain amount of tension and measures to prevent external damage.

Fourth, process performance: Process performance is an important condition for the design and selection of cable accessories, the installation process should be as simple as possible, to facilitate on-site construction with short construction period; and the requirements on the on-site environment and the technical level of workers are not high, furthermore, the installation quality is easily controlled, and the quality is reliable.

Fifth, the quality of manufacturer assures the system. Before the preformed cable accessories going out of the factory, as the rubber preform prefabricated stress cone, porcelain sheath, shell, dipping and the other parts provided by the manufacturer are assembled into the overall terminal or connector when installed in the field, therefore, manufacturing quality and workmanship of each of parts directly are related to the final quality of the product.
