TP-1521-10P3: 10 pairs 3-pole over-voltage protection magazine for LSA highband module, without GDT

LSA type  3-Point and 5-Point protection

We are  professional factory in the production of 314 connectors , LSA disconnection module , STB module  and other related accessories.

Descriptions    

10 pairs 3-pole over-voltage protection magazine for LSA highband module (TP-1521-10P3) 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 10 pair modular design magazine.







Main Features

5) Appearance: the color of all metal and plastic parts is uniform, without any scratch, rust, crusting and cracks.

6) The labels are clear and complete.

7) Flame retardant performance: all plastic parts and printed circuit board are flame retardant, reaching grade of GB/T5169.7FV-0

8) Nominal DC spark-over voltage (100V/s) : 230±20% V

9) Impulse spark-over voltage (1kV/us): ≤700V

10) Impulse discharge current (8/20us, 10 times) (a+b)-e: 5kA

12) AC discharge current (50Hz, 1s, 10 times) )(a+b)-e:5A

13) Capacitance(1kHz): ≤1.5 pF

14) Transverse voltage duration: ≤200ns

16) Insulation resistance: insulation between line a and line b, and/or between line a, b and grounding wire and alarming signal line, and/or between grounding wire and alarming signal line ≥ 1000MΩ. And after high temperature test, low temperature test, temperature varing test and humidity heat test, the insulation resistance ≥ 1000MΩ.

17) Contact resistance: under normal ambient conditions, the contact resistance between protector and block contacts ≤7 mΩ. After high temperature test, low temperature test, temperature varing test and humidity heat test, the increasing resistance ≤3 mΩ  And after inserting the connection cord (or test cord) into the module for 200 times, the increasing resistance ≤3 mΩ
