2027-25-C10LF

Gas Discharge Tube (GDT) Arresters are designed to protect electrical circuits and equipment from lightning and power surges. Specifically, GDT arresters are able to protect against direct lightning surges, high- ground potential differences, and fault-generated over-voltage transients. The 2027-25-C10LF is a specific type of GDT arrester product.

Features

The 2027-25-C10LF arrester features a high-performance zinc oxide (ZnO) composite. This composite offers an extremely fast surge response time, with maximum surges being handled in just one millionth of a second. It also provides superior insulation protection by using an insulated substrate, which is rated at up to 4000 volts. The arrester also includes a built in temperature sensor, which helps protect against overheating and allows for increased performance.

Application Field

This type of GDT arrester is primarily designed for use in high voltage applications, primarily those exceeding 1000 volts. It is typically used in power distribution systems, junction boxes and substations, as well as in agricultural, commercial and residential areas. The arrester is also well suited for use in locations with exposed wires, such as rooftop antennas and satellite dishes.

Working Principle

GDT arresters work by providing a low-impedance path for the surge current to travel, and also by utilizing the zinc oxide component to protect against overheating. In operation, the arrester acts as a \'short-circuit\' trap, allowing the surge current to pass through its discharge gap. The arrester then freezes, and immediately conducts electricity away from the protected circuit, thus preventing damage. When the surge current has been reduced to a safe level, the arrester then returns to its original position, ready to provide further protection should the need arise. This process is repeated on a regular basis, providing reliable protection against power surges and lightning strikes.

GDT arresters are widely used to protect a variety of electrical systems and circuits from damage due to power surges and lightning strikes. The 2027-25-C10LF model is specifically designed for use in high voltage applications, and is able to provide reliable protection against direct lightning and high ground potential differences, as well as fault-generated over-voltage transients. It features a high-performance zinc oxide composite, which provides extremely fast response times, enhanced insulation protection, and increased performance. The arrester also includes a built in temperature sensor, helping to further protect against overheating and reduce the risk of failure.
