What is 5 pairs over-voltage protection magazine used for? 


    DESCRIPTIONS    

5 pairs over-voltage protection magazine (TP-1503-5) is used for MDF disconnection block 71, 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 flame retardant, high temperature resistance and aging resistance. It is 5 pair modular design magazine.

    MAIN FEATURES    

• Modular 5 Pair Design: The magazine is structured to accommodate five pairs in a modular format, allowing flexible integration into MDF disconnection block 71 systems. This design simplifies expansion and ensures efficient use of available space.
• Easy Installations: Engineered for quick and straightforward mounting, the unit minimizes installation time and does not require special tools, making it highly convenient for field technicians.
• Maintenance Free: Built with durable materials and a robust structure, the protection magazine operates reliably without the need for regular servicing, reducing long-term operational costs.
• Graded 3 Point Protection: The inclusion of a graded three-point protection system ensures multi-level defense against over-voltage, enhancing reliability and safeguarding sensitive telecommunication circuits.
• Fail Safe (FS) Function: Designed with a fail-safe mechanism, the device provides an added layer of security by defaulting to a protective state under fault conditions, preventing network damage.
• Fast Response Time: The over-voltage protection responds rapidly to electrical surges, minimizing exposure time and reducing the likelihood of circuit failure or equipment damage.
• High Current Rating: Capable of withstanding high surge currents, the magazine ensures consistent performance even during significant transient events, maintaining system stability.
• High Insulation Resistance: The unit offers excellent insulation resistance, which reduces leakage currents and ensures reliable electrical isolation between contacts, improving long-term safety.
