حفاظت مدار برق‌گیر گازی (جی دی تی)

Product Attributes

Introduction

Gas discharge tubes are primarily used for overvoltage protection of telephone exchange main distribution frames and subscriber terminal equipment. Compared to conventional GDTs, they provide a higher level of protection, and their fast, precise breakdown voltage makes them suitable for MDF (Main Distribution Frame) modules, high-speed data telecom applications (e.g., ADSL, VDSL), and surge protection on power lines. They offer two forms of protection: combined with varistors to guard against the bulk of sustained voltage pulse spikes, and protection against transient overvoltages transmitted through telephone networks and control networks.

Features

• Overvoltage fault protection against energy surges
• Excellent pulse breakdown response for sensitive equipment
• Suitable for high-frequency applications
• High reliability
• Low arc voltage crowbar device
• Low capacitance (down to 1pF) and insertion loss
• Precisely engineered high-accuracy breakdown voltage, ranging from tens of volts to hundreds or even thousands of volts
• Selective short-circuit failure
• Low inter-electrode capacitance, high surge current capability from a few amperes to tens of kiloamperes
• Good insulation, no radioactive materials

Applications

• Telecom - MDF Modules
• xDSL Equipment
• RF System Protection
