Ceramic gas tube arrester are mainly used for the protections mentioned below.
* Main Distribution Frame (MDF)
The MDF is used for protection against the high energy disturbance from the external cable. That is usually called primary protection.
* User's terminal equipments, such as telephone, electrograph, modem and etc.
More and more extract electronic elements are used in telephones, electrographs and modems etc. Once an over-voltage occurs, the discharge tubes will protect the equipments by conducting the over-voltage current away to the ground.
* CATV, coaxial cable, video system, cathode ray tube protection
Our GDTs are particularly applicable for protecting coaxial cables of CATV networks. Because of low self-capacitance( about 1pF), the gas discharge tube will not occur disturbance to protected system even if in the events of high frequency. The discharge tube is placed in protection module and connected with the shielding layer and the ground.
Our company have a wide product range of gas tube arrester:
Voltage range: 75V, 90V, 150V, 230V, 350V, 470V, 600V, etc.
