Gas Discharge Tube Arresters (GDT) are devices used to protect circuits from voltage or current surges, such as those caused by lightning. The CG2230MS is a specific type of GDT known as a metal-oxide surge arrester and is used predominately in applications related to the telecommunications sector. Its designed working principle is based on the highly conductive nature of metals at high voltage levels.
When an unprotected device is subjected to a pressure wave created by a connectivity, the resistance of the internal metal-oxide arrester lowers and creates a large electrical current. This current is discharged, carrying the voltage and the energy of the wave through the device, leaving behind only limited or no damage. Upon completion of its task, the GDT unit returns to its original aspect without exhibiting any external damage, thus making it an important piece of telecommunications infrastructure.
The CG2230MS product itself is highly reliable and durable due to its construction materials and components, which includes a continuous gaseous gap insulation, external silicone coating, and a zinc-oxide element. This combination offers very good levels of impedance, capacitance, and leakage current, all of which are key metrics for selecting a GDT. In addition to telecom applications, the CG2230MS is also suitable for use in industrial transformer installations, even those exposed to lightning in complicated and hazardous environments.
At the heart of the CG2230MS arrester is its zinc oxide element, which works in a similar way to a resistor. It consists of a material with a high dielectric constant that sets a maximum threshold voltage limit. When the voltage exceeds this threshold, the resistance of the material falls rapidly, allowing a discharge circuit to be established. The primary function of this circuit is to rapidly and successfully prevent any overload or overvoltage of the protected electronic device.
A key function of the CG2230MS is its ability to cope with the high instantaneous peak voltages of lightning strokes. To achieve this, the arrester can be supplied in different versions to best suit the expected transient surge levels of any specific application. Furthermore, the zinc oxide element used is constructed using a patterned electrode structure. This further improves the response of the element and allows the device to handle charge levels up to and over hundreds of kilovolts per microseconds.
The CG2230MS arrester is also designed to operate in tandem with other electronic components to optimize its performance. Its components and materials are designed to have a low series inductance, allowing it to quickly and smoothly handle the enormous surge currents of lightning strokes. This provides valuable protection to any equipments connected downstream of the arrester.
In order to ensure the necessary surge protection levels, the CG2230MS arrester contains self-regulatory mechanisms that enable it to change its characteristics in order to adapt to changes in the supply line. This type of reliability, combined with its robust construction, makes the CG2230MS one of the most popular metal-oxide surge arrester choice for telecom applications, and many others too.
