Gas Discharge Tube Arresters (GDT) are positive temperature coefficient voltage-sensitive real-time protection components. They are installed in the positive and negative power lines of the transformer and connected in series. In normal operation, the arrester is non-conductive. When an abnormal high voltage occurs, a transient voltage that exceeds the normal operating voltage, a conductive path is formed within the arrester, and the electrical energy is conducted through the arrester. Thus, the transformer is protected from abnormal high voltage. In this way, the over-current protection function of the arrester works. Currently, due to the use of special materials with excellent properties, GDTs can be used as a cost-effective overvoltage protection solution in many applications, such as power lines, communications systems, and electronic circuits.

2027-35-BLF is a type of GDT protector. The device has a surge withstand capability of up to 10 kV, and a nominal discharge current of 5 kA. It is UL1449 approved, and is designed for a wide range of applications and configurations. The device is also designed with a unique self-restoring feature, which enables it to return to its original state once the overvoltage surge dissipates.

In terms of application field, 2027-35-BLF arrester can be used in the power industry, such as in industrial and mining equipment, solar power systems, as well as in telecommunications applications, such as optical communication systems, LAN systems, and radio-frequency amplifiers. It can also be used in optical transceivers, uninterruptible power supply systems, and electric vehicles. In addition, the 2027-35-BLF arrester can be also used in consumer electronics, such as digital cameras, laptops, and mobile phones.

The working principle of 2027-35-BLF arrester is related to its construction. The device is built with an insulating sleeve filled with a mixture of powdered osmium and metal hydroxides, and a lead-tin alloy wire inside. In a normal operation situation, the lead-tin alloy wire is in a contact-break state, and the insulation-sleeve of the arrester maintains high electrical isolation between the outside and inside parts of the device. However, when the power system is subjected to a transient voltage surge, the lead-tin alloy wire will conduct electrical current, and thus forming an inner conductive path. This will dissipate the surge and thus protecting the power system from transient voltage surge.

In conclusion, 2027-35-BLF arrester is a kind of Gas Discharge Tube Arresters (GDT) protector. It is designed with excellent surge withstand capability and can be used in a variety of applications and configurations, such as power lines, communications systems, and digital cameras. Furthermore, it features a unique self-restoring feature which enables it to return to its original state once the overvoltage surge dissipates. The working principle of the 2027-35-BLF arrester is related to its construction which includes an insulating sleeve filled with a mixture of powdered osmium and metal hydroxides, and a lead-tin alloy wire. When a transient voltage surge is generated, the lead-tin alloy wire will conduct electrical current thus forming an inner conductive path that dissipates the surge and thus protecting the power system.
