Insulator

A: An insulator is one kind of material where the internal electric charge of this does not run freely; insufficient electric current will run through it in the power of an electric field.

A: They are pin, suspension, strain, shackle, and stay.

A: They are paper, plastics, rubber, Styrofoam, glass & dry air

A: Once breakdown voltage is applied to insulator then it will become conductive so this is known as insulation breakdown.

A: CE,TSE,ROHS,ISO9001 and so on

A: Yes, we can make the products as different’s special require

A: We usually reansport by EXPRESS,such as DHL,TNT,FEDEXEMS for small order
Transport by sea ,by air or by train for huge quantity.

A: Sample order in stock. and 5-10days for bulk production

A: Normally, the warranty for the product is one year, warmly reception with the calling, visiting and letters, and give the best answers and solution in time from the customers for the technical problem.

A: Yes, it is! Our products can be Customized. We have design and engineer teams,we can customize products according to customers' drawing or requirements.

A: It depends your order quantity and it normally takes about 15-20 days.

A: Insulators were developed over the course of more than 100 years, for a variety of applications including telegraph, telephone, and electric power distribution. Many shapes evolved to hold the line wire more efficiently or to increase the insulating ability. Larger insulators were developed to meet changing needs as larger heavier wires or higher and higher line voltages were used. In addition, some insulator shapes were designed for special applications. Many insulator companies would patent special shapes, designs or other attributes, even if in reality the invention proved impractical. Take a look at some of the varied shapes of insulators.

A: In general, insulators were not made in specific colors for any reason. The natural materials that were used to make glass, including sand and glass cullet, tended to make light aqua to aqua colored insulators. Some batches were more green, others more blue. In addition, some trace chemicals would alter the color of the insulators. Also, since all glass is produced using some glass cullet, the composition of the cullet would also have an impact on the color of the resultant insulator. Take a look at some of the varied colors of insulators.

A: There are many factors that determine an insulator's value. Shape, color, embossing, condition, desirability and rarity all affect its value. Most insulators are quite common and have little monetary value. The first step in determining your insulator's value is to determine which insulator you have. Even with a price guide in your hand, you have to determine which of the approximately 460 shapes, 2800 different embossings, and almost 9000 color combinations best describes your insulator. (And those numbers don't even include any foreign or porcelain insulators!) It is easy to list the common insulators, and also list the very rare insulators, but it is difficult to list all the thousands of collectable insulators that fall between those extremes! A slight difference in the shape of your insulator can affect its value by twenty fold or more. A slight difference in color can also significantly affect the value of your insulator. Unless your insulator is either very common, or very rare, it is best to consult a knowledgeable insulator collector or dealer; or to educate yourself and invest in one of the good insulator books available. If you are serious about collecting insulators, getting a good insulator reference book is a "must".

A: Some insulators, such as strain, spool and pins, have a lower or upper surface area that remains unglazed in the finished product. This is because in during the high temperature firing process in the kiln, this is the area where the insulator is supported and therefore is not glazed. The above does not mean that this unglazed area can absorb any type of moisture, since at the such high firing temperatures the ceramic material goes into a vitrified state which makes it completely waterproof.

A: Please refer to GAMMA’s 2008 Technical Bulletin 53 “Guidelines for insulator cleaning” in accordance with IEEE STD 957.

A: Each insulator design has a standard radio-influence value. Check out the various ANSI models in our catalogues. It prevents the insulator from generating noise at high frequencies that might affect telecommunications. If the value is lower, it will generate less noise and there will therefore be less interference in telecommunications.
