Main Distribution Frame (MDF) is the device that terminates external communication cables and exchange or access equipments in the telecommunication system.
TP-1401-100 100 pairs MDF terminal block is used on the vertical side of the MDF, which is used for the termination between external lines and jumper wires. It adopts the IDC connection methods. It consists of 20 pieces 5-pair modules. Our TP-1503-5 protection magazine can be inserted into the block, with the function of protecting personnel and equipments against over voltage.
Technical Parameters
1) Working temperature: -30℃ ~ 60℃
2) Storage temperature: -35℃ ~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, complete and durable.
7) Insulation resistance: under normal ambient conditions, after high temperature test, low temperature test, temperature varying 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 varying 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 varying 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 varying 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 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: 0.32mm-0.6mm, while insulation ≤ 1.4mm
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
