Gas Discharge Tube Arresters (GDTs) are a form of surge protection device. They are used to protect sensitive components in a wide variety of electronic and electrical systems, such as sensitive medical equipment, communication equipment, industrial and process control systems, and consumer electronics. GDTs provide protection against high-voltage transients such as lightning strikes, voltage fluctuations, and other power surges. The CG7150MS is a high-performance Gas Discharge Tube Arrester developed by GDT Technologies in collaboration with major military and industrial partners. Its fully insulated aluminum housing provides highly reliable and cost-effective surge protection solutions for both indoor and outdoor applications.

The CG7150MS is designed for installation on a primary power line, providing reliable surge protection from high-voltage transients to downstream equipment connected to the primary power line. It has a fast response time and a high-frequency withstand capability. The device also has excellent self-cleaning properties, providing maximum surge protection even in the presence of high-voltage transients. A wide range of surge voltages can be protected using the CG7150MS, from 5kV/3kA to 80kV/2kA, ensuring optimal surge protection for a variety of applications. In addition, the device has an integrated interlocking system to prevent back-feeding and secondary arcing during a surge event.

The CG7150MS employs a gas-filled, low breakdown voltage device as its main element. The main element is a sealed enclosure containing an inert gas at a low pressure and a metal-to-metal arrester element. The arrester element consists of two parallel metallic plates which are separated by insulating material. At normal operation, the applied voltage between the metal plates results in current moving from one plate to the other, creating an electric arc. If a transient voltage occurs, the gas ionizes, reducing the return current, thus limiting the energy transferred to the protected equipment.

The CG7150MS includes two terminal blocks, one for the primary power input and the other for the protected equipment. The device has built-in overvoltage protection, which is activated when the overvoltage exceeds the rated working voltage. This trips the arrester, de-energizing the protected equipment. In addition, the device is equipped with a re-triggerable device which allows for repeated surge protection cycles. The device also features a maintenance indicator that tells when the device needs to be replaced.

The CG7150MS is a robust and reliable GDT designed for a wide range of applications. It provides fast response time, excellent surge protection, and built-in overvoltage protection. The device is suitable for both indoor and outdoor applications and has a wide range of surge voltages that can be protected. Its maintenance indicator allows for timely replacement of the device for optimal surge protection.
