Use And Classification Of Insulating Sleevings

Aug 31, 2017

    Separate the electrically charged parts from the electrically charged parts or with the parts with different potentials, so that the current can flow according to the route specified by the people, and the insulating material is an essential material in the electrical products. Heat shrinkable tube insulation materials are widely used in the field, in addition to generator manufacturing and transmission and transformation equipment, but also widely used in a variety of electrical, electrical products, communications, electronic products, household appliances, transportation, automobiles, rail transport and vehicle manufacturing, aerospace and machine 悈 manufacturing and other fields. It can be said that insulating materials are everywhere.Insulating Sleevings

    Heat-shrinkable tube insulation materials widely used, involving a variety of areas, usually pay more attention to the small details of life, you will find everywhere there is insulation material figure. Excellent electrical insulating coating. Good electrical properties, thermal properties, mechanical properties and chemical properties. Many for the varnish, also colored according to the working temperature difference, according to the heat-resistant index can be divided into 90, 105, 120, 130, 155, 180 and 180 above seven grades.Insulating Sleevings

    According to the use can be divided into: impregnated insulating varnishes, for winding impregnation insulation, enameled wire paint, insulating layer used as a conductor, silicon-steel sheet paint, insulating layer for silicon steel sheet, cover of insulating varnish, used as a protective layer of the winding of impregnated insulating, to prevent mechanical damage or assembly convenience; Insulating materials such as laminates, insulating coatings for special insulating varnishes such as resistors, capacitors and potentiometers.Insulating Sleevings

   The composite insulating casing is used as insulating medium for oil or gas, which is usually made into a transformer casing or circuit breaker bushing, which is usually applied to the voltage level below 35,000 volts. The inner cavity of the composite insulated casing conductor and the porcelain suite is filled with transformer oil and plays a radial insulating role. When the voltage exceeds 35,000 volts, the conductor is sheathed with an insulating tube or a package cable to enhance insulation. The conductor structure of composite insulated casing has two kinds of cable-type and guide-Rod. The cable-type use of the transformer's lead cables directly through the casing, easy installation. When the working current is greater than 600, the cable-type structure is difficult to install, generally using the guide bar structure.Insulating Sleevings

   The capacitive casing is composed of a capacitor core, a porcelain sleeve, a metal accessory and a conductor. Mainly used in EHV transformers and circuit breakers. Its upper part is in the atmosphere, the lower part works in the fuel tank. capacitor-type casing capacitor heart as an internal insulation, porcelain sleeve as an external insulation, also play a role in protecting the capacitance of the heart. The electric field of the porcelain sleeve surface is evenly distributed by the pressure of the inner capacitance heart, which improves the electrical insulation performance of the casing. The metal accessory has intermediate connection sleeve (flange), end cover, equal pressure ball and so on. The conductor is a cable or a rigid steel pipe.Insulating Sleevings
