Gas Discharge Tube Arresters (GDT) are an important part of power distribution and protection systems. CG110MS is a high-performance GDT that offers high-quality protection for power systems and critical applications. It has a wide range of application fields and a working principle that ensures optimal protection of equipment.

The primary application field of CG110MS is in medium voltage systems, typically operating at 48 to 52kV. It is also suitable for application in low voltage systems operating at 12 to 24kV. The arrester is designed for protecting the network from lightning induced voltage surges and overvoltage disturbances from other sources. Its lightning arrester class is 10kA and its data sheet provides information on the arrester’s characteristics, including protection level, rated voltage and current, and other relevant performance parameters.

The CG110MS working principle is based on a principle called voltage limitation. In this principle, the voltage magnitude is limited to a safe level through the limitation of the discharge current. This is achieved by the integrated varistor in the GDT. This varistor limits the voltage to a safe level and provides protection against overvoltages. At the same time, the arrester can suppress lightning-induced transients on the power line.

Moreover, the GDT is designed for high-performance thermal stability, steady state durablity, and superb electrical surge characteristics. The overvoltage protecting element is a metallized polypropylene film, which has an excellent durability and long anti-puncture life. Its excellent performance is maintained even under severe environmental conditions.

The build up of a shielding gas maintaining an inert layer between the electrodes helps to protect the varistor from the surge current. The gas helps to reduce the operation of the arrester and eliminates the possibility of arc formation. This contributes to a longer life span of the CG110MS.

In addition, the arrester incorporates clever design features to increase its protection. For instance, the GDT includes a voltage protection zone that limits the arrester voltage in order to provide enhanced protection. Moreover, an electrical safety network system is used to reduce the occurrence of arcing. This system helps to control the power flow through the arrester and prevents the development of hot spots on the varistor.

CG110MS has been designed to provide optimal protection of a variety of sensitive equipment in power systems. Its features and benefits make it an excellent choice for medium and low voltage applications. It is easy to install and its working principle ensures reliable protection of the equipment and network.
