Glass insulators do not require periodic live preventive tests on insulators during operation. This is because each damage of tempered glass will cause the damage of insulator, which is easy to be found by operators during line inspection. When the insulator is damaged, the glass fragments near the steel cap and iron foot are stuck, and the mechanical strength of the remaining part of the insulator is sufficient to prevent the insulator string from breaking off. Due to the high mechanical strength of the surface layer of glass insulator, the surface is not easy to crack. The electrical strength of glass generally remains unchanged during the whole operation period, and its aging process is much slower than that of porcelain. Therefore, glass insulators are mainly scrapped due to self damage. Advantages: the mechanical strength of the surface layer of glass insulator is high, the surface is not easy to crack, and the aging speed is slow; It can cancel the live periodic preventive test of insulators during operation, and there is no need to carry out "zero value" detection during operation, so the operation and maintenance cost is low.

An electrical insulator is also called a power insulator, it is an essential component in the overhead line and transmission line systems, it is usually mounted on the power towers, poles or other structures to prevent the electric current from flowing to the unwanted regions from the overhead conductors. The material of the electric insulator is different from others such as conductors and semiconductors, the electric charges do not flow freely when it is passed through the electrical insulator. In case you would like to buy this quality electrical insulator for the transmission line, contact us and we will send the free quotation. We are ranked among the best electrical insulators manufacturers in China. There are different types of materials that are used for making electrical insulators for overhead lines. Each of these insulating materials has distinct physical insulating properties. It is vital to know the properties of each electrical insulator material before choosing it. Powertelcom manufactures different types of electrical insulators, which are used in a wide range of applications. Otherwise, the electrical insulators for powerlines are divided into the following types: Pin type insulator , Post type insulator , Strain insulator, Suspension insulator , Shackle type insulator also called spool insulator and Stay insulator. Depending on the volume of current, the insulators are divided into low voltage insulators, medium voltage insulators, or high voltage insulators.

This material also offers greater mechanical strength to enable electrical installers to crank up closer height tolerances than with porcelain insulators, making Storm's standoff insulators more suitable for ground bar and perimeter grounding applications. They combine high mechanical strength with high arc resistance and dielectric properties at elevated temperatures and humidity. These shatter resistant insulators meet the most exacting standards for a variety of applications. Tensile strength is the amount of stress that the insulator will withstand when pressure is applied pulling straight up on the bolt in the insert. Cantilever strength is the amount of weight an insulator will support when something is hung on an insulator that is mounted on the wall.
