High voltage insulators for sale

Glass insulators do not require periodic live preventive tests on insulators during operation. This is because each damage of tempered glass freestreams live1 cause the damage of insulator, which is easy to be found by operators during line inspection. When the insulator is damaged, high voltage insulators for sale, 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.

Packaging Details: Wooden case and pallet, or according to customer's requirement Delivery Time: 30days after order confirmed. Insulators are commonly used as a flexible coating on electric wire and cable. Since air is an insulator, in principle no other substance is needed to keep power where it should be. High-voltage power lines commonly use just air, since a solid e. However, wires which touch each other will produce cross connections, short circuits, and fire hazards. In coaxial cable the center conductor must be supported exactly in the middle of the hollow shield in order to prevent EM wave reflections. Finally, wires which expose voltages higher than 60V can cause human shock and electrocution hazards. Insulating coatings help to prevent all of these problems. The Toughened glass insulators of cap and pin type is used high-voltage, ultrahigh voltage and extra high voltage alternating current and direct current transmission lines and hanging wires. It consists of iron cap, toughened glass and insulator pin. And owing to light weight, high intensity and large creepage distance , it can save metallic materials and reduce line cost. Annealed tough glass is used for insulating purpose.

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. Compression strength is the amount of weight an insulator will support in a direct vertical application of pressure. Arc resistance is expressed as the number of seconds that a material resists the formation of a surface-conducting path when subjected to an intermittently occurring arc of high voltage, low current characteristics. A standoff insulator's height determines the distance that will separate a source of voltage from ground or other components. Since an electric current will jump across a gap, the greater the voltage, the greater the distance required for safety.

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.
