SH145

Gas Discharge Tube Arresters (GDT) provide reliable protection of electrical and electronic systems against transient over voltages. The SH145 is typically used to protect power lines. It is a compact, low profile, and cost-effective GDT arrester.

In general, electric arrester protection works by diverting surge current away from the power line. This is accomplished by using a GDT device. A GDT works by absorbing the surge current and storing it temporarily. Then when the surge current dissipates, the stored energy is released. By using a GDT instead of a traditional fuse, electrical systems can be better protected.

The SH145 is a surge protector that is designed to be used in combination with a power line circuit breaker. The SH145 is a two-pole GDT device. It has an isolated field plate flightcone that is arranged between two GDT elements. This provides good electrical insulation and also reduces lateral energy loss. The SH145 also has an integral fault monitor that monitors the power system for any fault currents. This provides additional protection against transient over voltages.

The SH145 is designed for outdoor use and is rated to operate up to rated currents of up to 40kA and its continuous current rating is up to 5kA. The SH145 has an excellent surge rating with a peak current of 365kA, and has a response time of just 2.5µs. The GDT elements are encapsulated in a heat-resistant casing, providing superior protection from lightning surges.

The SH145 has a wide operating temperature range and can operate efficiently from -25 to +75 degrees Celsius. It can also be used in most environmental conditions, including dust, moisture, and extreme temperature variations. The SH145 is designed to provide reliable protection to the power supply in a range of applications, including utility substation power lines, industrial equipment, telecommunications, and computing.

The SH145 is a cost-effective way to protect power supply systems from transient over voltages. Its compact design and low profile make it easy to install and maintain. It provides reliable protection for a range of applications, ranging from industrial environments to telecommunications and computing.

The SH145 is also one of the most economical GDT arresters currently on the market. It is lightweight and easy to install, as well as providing excellent surge protection. The SH145 is a great choice for protecting power supply systems from surge currents.
