Gas Discharge Tube (GDT) arresters are one of the most important components of any electrical network, as they can protect sensitive electrical equipment from damaging over voltage surges. The use of GDT arresters has become increasingly important in recent years, as the prevalence of lightning strike and other events causing surges has grown.

The 2035-40-SM-RPLF application field and working principles of GDT arresters are based on the principle of ‘impulse lightning protection technology’. This technology works by using a series of electrodes positioned inside the GDT arrester, which form a capacitance between them. When the electrical network is exposed to a surge, the electrodes cause a spark gap to be created, which discharges the surge from the network.

The 2035-40-SM-RPLF is designed for medium voltage (up to 40kV) lightning protection. It is commonly used for outdoor medium voltage distribution networks, and its housing is made of cast iron with an EPDM rubber layer for extra protection from moisture and other atmospheric influences. It also features an improved spark gap design, which helps to suppress high energy transients and provide increased protection.

The working principle of the 2035-40-SM-RPLF GDT arrester is that the spark gap is triggered when the electric field intensity near the electrodes exceeds a certain threshold level. When this occurs, the gap discharges the transient energy into the ground and prevents it from reaching the main circuit. The spark gap also acts as a resistor, preventing any further current from flowing from the electrodes into the main circuit. This helps to protect sensitive equipment, ensuring that disruption to the network is minimized.

The 2035-40-SM-RPLF GDT arrester provides effective lightning protection, helping to ensure that network equipment is not damaged by overvoltage surges. It is also robust and durable, with an improved spark gap design for increased protection.
