Test Connection Block Main Distribution Frame Data Distritution Frame protection connection block Optical Wiring Module Summary:Protection connection block is use in relay the following 2M to the local network or public communication telephone copper wire at the entrance, providing a range of over voltage, over current four sound and light alarm system. Can clearly distinguish visual alarm circuit to prevent external over-voltage over-current signal to the telephone exchange damage. Using for the internal and external wirings to the switch and accerss line to the user .Feature1. Reed surface of silver, copper with high-quality elastic material that can be wire diameter of 0.4 ~ 0.6mm2. Shell of high quality plastic, with a grounding and alarm devices.Main performance parameters:Working conditions:(1) Working temperature: 0 ~ +40 (degree) (2) Relative humidity: ≤ 85% (30 degrees)(3) Atmospheric pressure: 70 ~ 106 (kpa)Electrical properties:(1) Insulation Resistance ≥ 1000MΩ(2) high-voltage protection> 3000V (DC) / mm without breakdown, no arc.(3) Contact Resistance ≤ 7mΩ between reed wire and terminal into the connection between the contact resistance ≤ 3mΩ(4) Pull strength: ≥ 25N(5) Plug time : ≥ 200(6) Fire-retardant plastic indicators: GB/T5095.2-97(7) Respond to alarm time: ≤ 2 stest connection blockMain distribution frameData distritution Frameprotection connection blockOptical Wiring ModuleDigital Distribution FrameGeneral Distribution Frame Optical Fiber FrameMain Distribution FrameSplice ClosureANSHI Main Distribution FrameANSHI MDF 100 Pairs Protection Connection Block
