Product Description

 

Material: Alumina Ceramic, Al2O3, Aluminium Oxide
Today about 80 percent of power network operators decide in favour of vacuum switching technology. The core component of this switching principle is the vacuum interrupter. Vacuum Interrupters are used for repetitive switching, motor in rush current interruption, fault protection, over current and short circuit protection. They can reliably switch high stress currents robustly without the need for unreliable cooling or ventilation systems.

Product Feture


Long Life & High Reliability
Fast Interrupting Speed
Rapid Dielectric Recovery

Applications


1. Circuit breakers
Vacuum interrupters are used in circuit breakers in the most demanding electrical circuit protection applications to minimize damage caused by electrical overloads or short circuits.

2. Load break switches
Vacuum interrupters are used in load break switches to connect and disconnect electrical load currents providing limited load switch capacity.

3. Reclosers
Vacuum interrupters are used in reclosers to automatically open and close distribution circuits in response to transient overload and fault conditions.

4. Contactors
Vacuum interrupters are used in contactors in demanding applications that require a high number of operations switching a power circuit in electric motors, lighting and heating devices, capacitor banks, and the like.

5. Tap changers
Vacuum interrupters are used in tap changers inside transformers to change the winding connections to deliver the required voltage.

6. Railway circuit breakers
Vacuum interrupters are installed in the circuit breakers on top of this special locomotive to supply electrical energy to railway locomotives' electric drive motors.

Q:How should the coffee stains in the ceramic coffee cup be cleaned?
Coffee and help people digest effect, often using ceramic cup to drink coffee can help you promote gastrointestinal absorption, fat consumption, so as to help you achieve the effect of weight loss, but also carry the oxidation effect, so it can prevent aging in a certain extent, so universal by the majority of the crowd favorite.

Q:How much money 100 pounds of ceramic jar probably?
That day, watching TV, 100 pounds of vinegar special big pot is 8000Compare it to you
Q:Ceramics are not crystalsTell me the exact answer. Thank you for your cooperation!
Its scientific name is "three oxidation two aluminum", which is typical of engineering ceramicsAs for our daily use of ceramics for daily use, the main ingredient is kaolin, although it does not seem crystal clear, but it is composed of many small grains, but also crystals
Q:Vary render ceramic parameters

Q:What do ceramic and Bone China
Reporter recently in the country into a modern department store opposite the kitchen special store to see, a lot of customers moved to new homes in a carefully selected bone china tableware, a lady said: "only a few years to buy anyway, to pick a good buy, to ensure the quality of life, of course, is my preferred Bone China tableware."China has many outstanding advantages: fine texture, the milky white, translucent in the light, the most valuable is much lighter than the ordinary ceramic bone china, the maintenance is simple, with oil cleaning, without detergent, just use warm water to clean on the line. It can be put into the sterilizing cupboard and sterilized at high temperature. If scratches can be polished lightly with toothpaste, if there is tea, with lemon juice or vinegar wash. Bone china tableware is fastidious about the matching, each set has a name such as "a quality suggestive of poetry or painting, rhyme book" fragrance "," Moonlight ", a harmonious union lasting a hundred years", each set of tableware patterns with a face, create an atmosphere, therefore, what kind of decoration style houses what kind of choice, bone china tableware style, see is the owner's personality and style. Daily meal, the feast, with enough graceful bone holding, will show the extraordinary style.The bone in his hand, to the light observation of porcelain porcelain hand feel transparent, delicate and hard, the index finger of a bomb, a "crisp sound bite". A long knock heart had finally been answered. When connected, it is the future on the lips, gazing at the beauty of the porcelain
Q:Ceramic knife?! Listen, why are you so fragile? Can you cut bones?
Ceramic knife is not suitable for food, Duo food need to be cut down, so in addition to bones, coarse fish...... Other hard ingredients are not suitable for use with ceramic knife dishes, such as frozen meat, vegetables, fruit pulp, raw fish, bamboo shoots (excluding shell), meat, seafood, shellfish, shellfish...... And other non rigid food can be used.
Q:Development history of Chinese ceramics
Development history of Chinese ceramics:In the early Neolithic age, 7000-8000 years ago, the ancestors of our country had already started making pottery. Because of the low social productivity and the low level of material civilization of the society, the pottery of the new stone age was characterized by its rough and primitive simplicity. In the late Neolithic Yangshao culture, mining culture, Hemudu Site culture Qu Ling, Dawenkou Culture, Longshan culture ten cultural relics, unearthed a large number of ceramics, the main varieties of pottery, pottery, pottery and geometric pottery etc.. The original colored pottery and painting are decorated with geometric shapes. The techniques are rough and the composition is novel and smooth. It shows the artistic level of Chinese pottery at that time. Longshan culture pottery little decoration, but the overall round straight, thin wall and uniform, showing amazing skills.
Q:What are the new ceramic products?
fine ceramicsThis new type of precision ceramic building materials) a Japanese company developed is a mainly composed of water soluble latex powder, such as 100 grams and 20 grams of cement cell ceramic in the effect of hydrolysis of a mixture of calcium, will completely eliminate the effect of hydration occurred in the degrees of freedom, can make life extension 4 to cement 5 times tolerance degrees Celsius when using non water model (plastic mold, can be obtained with the same ceramic luster.
