What is a 3 pole Over-voltage Protection Magazine pigtail used for? 


   DESCRIPTIONS   

MDF over-voltage protection magazine (TP-1502-10P3) is used for LSA modules, which forms the protection circuit for the protection of exchange room equipments and personnel against over voltage, for mainly as follows:

• The surge voltage caused by lightning on or around the outside lines.
• The short-time AC voltage inducted on external lines, when the power line, the power system or the electric railway system is broken down in the neighborhood of the outside line.
• The outside line directly collides against a 220 V power line.

 
The housing of the magazine is high temperature resistance and aging resistance. It is 10 pair modular design magazine. Manufactured with high-quality insulating and conductive materials, the magazine offers excellent thermal stability and long service life. The GDT arrester inside is designed for quick response and low let-through voltage, ensuring compliance with international telecom safety standards. Its design emphasizes both safety and practicality, making it suitable for modern telecommunications infrastructures requiring stable surge protection.

   MAIN FEATURES   

• Modular 10 Pair Design: The magazine is built to protect 10 pairs in a single module, making it compact and efficient for distribution frames. This modular approach saves space and simplifies wiring arrangements in high-density telecom environments.
• Easy Installations: Designed as a plug-in unit, it fits directly into standard LSA profile modules without requiring tools. This allows technicians to complete installations or replacements quickly, reducing downtime in the field.
• Maintenance Free: The sealed and durable construction ensures that the magazine operates reliably without the need for periodic servicing. This helps minimize operating costs and keeps network protection stable over long service periods.
• Graded 3 Point Protection: With line-to-line and line-to-earth pathways, the unit provides three-pole protection against over-voltage conditions. This graded system ensures that sensitive telecom circuits are safeguarded from multiple types of surge threats.
• Fast Response Time: The integrated GDT arrester reacts almost instantly when an over-voltage event occurs. This quick action minimizes the exposure of connected devices to damaging surges.
• High Current Rating: The protector can safely handle high surge currents, ensuring durability during repeated lightning strikes or power surges. Its robust rating guarantees long-term performance even under heavy surge conditions.
• High Insulation Resistance: The unit is designed with high-grade insulating materials that prevent leakage currents between pairs. This ensures stable signal quality and maintains the integrity of the protected lines.
