Outdoor 1 pair STB module DP box

Outdoor 1 pair STB module distribution point DP box 

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

Description

Distribution Point (DP) box is used in terminating cables of secondary telephone network to the cable pairs of subscriber line. It consists of the housing and STB modules. The housing consists of body and cover. The STB modules provide a connection between an exchange side cable pair and a distribution pair. It is for outdoor applications. 

Main Features

Made of highly impact resistant PC

Flammability according to UL 94 FV0

Protection IP 50

Smallest distribution box designed for outdoors

Easy operation and wide range of wire

Technical Paramters

1) Working temperature: -45℃ ～ 60℃

2) Storage temperature: -50℃ ～65℃

3) Relative humidity:  ≤85%(+30℃)

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) Insulation resistance: under normal ambient conditions, after high temperature test, low temperature test, temperature varing test and humidity heat test, the insulation resistance between any two independent contacts, and/or between contacts and metal parts ≥ 1000MΩ

8) Contact resistance between contacts: under normal ambient conditions, the contact resistance between 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

9) Contact resistance between conductor and contact: under normal ambient conditions, the contact resistance between contacts ≤3 mΩ. After high temperature test, low temperature test, temperature varing test and humidity heat test, the increasing resistance ≤2 mΩ. And after terminating for 200 times, the increasing resistance ≤2 mΩ.

10) Dielectric strength: under normal ambient conditions, after high temperature test, low temperature test, temperature varing test and humidity heat test, the insulation resistance between any two independent contacts, and/or between contacts and metal parts is able to withstand an AC voltage of of 1000V (virtual value) at 45Hz~60Hz sinowave for 1 minute, without spark over and flying arc

11) Gas tight performance: contact touches the conductor at both sides, and thus forming the gas tight area, while the area of gas tight occupies ≥50% of the touched area on each side.

12) Conductor diameter range: 0.4mm-1.05mm, while insulation ≤ 5mm

13) Pulling strength:≥25N while pulling from the vertical side of the contacts

14) Flame retardant performance: all plastic parts are flame retardant, reaching grade of UL FV0

15)  Life circle: ≥200 times

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

17) Impulse spark-over voltage (1kV/us): ≤750V

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

19) Impulse discharge current (10/1000us, 300times) (a+b-e):100A

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

21) Capacitance(1kHz): ≤1.5 pF

22) Transverse voltage duration: ≤200ns

23) Fail-safe response time: ≤15s
