Teflon tube product features
1. High chemical stability: It can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, strong bases, strong oxidants, reducing agents and various organic solvents. Ideal for high purity chemical feeding use.
2. Low friction coefficient: The friction coefficient is generally only 0.04, which is a very excellent self-lubricating material, and the friction coefficient does not change with temperature. 3
3. Excellent anti-adhesion, the inner wall of the tube is not easy to adhere to colloids and chemicals.
4, excellent aging resistance, can be used outdoors for a long time.
5. Excellent electrical insulation properties: PTFE is a highly non-polar material with good dielectric properties, great resistance, and a dielectric constant of about 2.0, which is the smallest among all electrical insulation materials.
Part of the tube has high transparency and can easily observe the internal fluid condition.
Transformer bushing is the main insulation device outside the transformer box, the outgoing line of the transformer winding must pass through the insulation sleeve, so that the outgoing line between the outgoing line and the insulation between the outgoing line and the transformer shell, while the role of fixed outgoing line.
Due to different voltage levels, the insulating sleeve has the form of pure porcelain sleeve, oil-filled sleeve and capacitor sleeve. Pure porcelain bushing is mostly used for transformers of 10kV and below. It wears a conductive copper rod in the porcelain bushing and is air insulated in the porcelain bushing. Oil-filled bushings are mostly used in 35kV transformers. They are used to fill oil in porcelain bushings, wear a conductive copper rod in porcelain bushings, and the copper rod is coated with insulating paper. Capacitor bushing is used for high voltage transformers above 100kV and consists of main insulated capacitor core, outer insulated upper and lower porcelain, connecting sleeve, connecting sleeve, oil pillow, spring assembly, base, equating ball, measuring terminal, terminal, rubber washer, insulating oil and other components.
With the development of China's power industry, the power supply is increasing year by year, and power transformers are gradually developing in the direction of high voltage and large capacity. At the same time, due to the improvement of manufacturing technology, the insulation distance of each part of the transformer product is gradually reduced, so that the capacitor bushing as a transformer supporting product has stricter requirements on its appearance and size.
At present, many transformer bushings use Teflon tubes, because Teflon has excellent performance, meets the insulation conditions required for transformers, and has high temperature resistance, corrosion resistance, acid and alkali resistance, and friction resistance.
