TP-1521-10P3G: 10 pairs 3-pole over-voltage protection magazine for LSA highband module, with GDT
We are professional factory in the production of LSA disconnection module ,STB module and other related accessories.
Description
1)MDF over-voltage protection magazine 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:
2) The surge voltage caused by lightning on or around the outside lines.
3) 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.
4) The outside line directly collides against a 220 V power line.
5) The housing of the magazine is flame retardant, high temperature resistance and aging resistance. It is 10 pair modular design magazine.
Main Features
1) Modular 10 pair design
2) Easy installations
3) Maintenance free
4) Graded 3 point protection
5) Fail Safe (FS) function
Technical Parameters
1) Working temperature: -20°C ~ 60°C
2) Storage temperature: -40°C ~80°C
3) Relative humidity: ≤85%(+30°C)
4) Atmospheric pressure: 70kPa ~106kPa
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
11) Impulse discharge current (10/1000us, 300times) (a+b-e):100A
12) AC discharge current (50Hz, 1s, 5 times) )(a+b)-e:5A
13) 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.
14) 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
