Gas discharge tube arresters (GDT) are designed to provide protection for components and equipment from damaging high voltage transients. They are commonly used in circuits with high voltages and in industrial applications, such as telecommunications, electric power transmission and distribution, and other high voltage applications. The CG43.0SM arrester is a GDT that is designed to protect electrical equipment from surges in both alternating (AC) and direct current (DC) voltages.

The CG43.0SM is an advanced silicone rubber molded device that offers superior protection and performance. It is designed with a conduction upper part and a silica gel and rubber lower part, thereby allowing for a small enough size to fit into any housing or panel. Additionally, the CG43.0SM is waterproof, so it can be used in both indoor and outdoor applications.

The working principle of the CG43.0SM is based on its unique design. A silicon rubber lower part acts as an insulator, while a conduction upper part acts as a conductor. When a high voltage surge enters the arrester, the voltage causes a spark gap to open between the upper and lower parts. This spark gap sends a surge current into the upper portion of the arrester, which is then diverted to ground, thus stopping the surge.

The upper portion of the CG43.0SM is designed with an internal resistor which limits the surge current and provides a low resistance path for the high voltage surge to be diverted to ground. This prevents any damage from the surge to the protected components and equipment. Once the surge is diverted, the protective resistor acts as an energy limiter, limiting the amount of energy passed through the arrester to the connected equipment. This further reduces the risk of any damage from a high voltage surge.

The CG43.0SM is a highly reliable and efficient arrester that is suitable for a variety of applications, including AC and DC power lines, station protection, electronic equipment, and circuit boards. Its compact size, superior protection, and wide operating temperature range make it an ideal choice for protecting components and equipment in both indoor and outdoor applications. Additionally, its long life expectancy makes it an excellent choice for long-term protection.

The CG43.0SM GDT arrester is a reliable and effective device for protection against high voltage transients. Its unique design allows for a small size and its internal resistor provides reliable protection and excellent energy limiting capabilities. It is suitable for a variety of applications and provides superior protection from surge events.
