10 pairs Subscriber Terminal Block STB Drop Wire distribution box with protection
Product Description
Outdoor 10 pairs distribution point DP box for STB module telecommunication equipment
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, which house STB modules on the back mount frames. The STB modules provide a connection between an exchange side cable pair and a distribution pair. It is for outdoor applications.
Main Features
1) Made of highly impact resistant ABS+PC
2) Flammability according to UL 94-V0
3) Protection IP 55
4) Smallest distribution box designed for outdoors
6) Easy operation and wide range of wire
Technical Parameters
1) Working temperature: -20℃ ～ 40℃
2) Storage temperature: -25℃ ～55℃
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.
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
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
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.
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
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.
Conductor diameter range: 0.32mm-0.6mm, while insulation ≤ 1.4mm
Pulling strength:≥25N while pulling from the vertical side of the contacts
Flame retardant performance: all plastic parts are flame retardant, reaching grade of UL FV0
Life circle: ≥200 times
