Krone 6000 lines Modular Main Distribution FrameSummary1.Main Distribution Frameconstitute of the frame body, connection block, test module, alarm systems, test equipment, over voltage and over current protection unit and so on,Main Distribution Frameis use to connection with the switch and the user cable, patch cord, over current, over voltage protection and alarm test function, the implementation of YD/T694-2004 standard products. 2. The double sidemain distribution framemade by advance aluminum-alloy with safety grounding system facilitate instalation and enlarge capacity. 3.The single side main distribution frameimprove the advantage of double side main distribution frame,the termination of both external side and exchange side are on the front;the operation of jump wire,alarm system,protectors are also on the front. It completely realizes the front-operation which reduce the space requirement and laying wires regulary it is facilitate operation and maintenance. 4. It adopts a built-in structure, the possible faulty points have decreased in number, and the removal of the modules does not affect the normal working of the alarm system. Features:1. All aluminum alloy frame, rigid, elegant appearance, a variety of cable connecting all with Built-in card access methods, safe and reliable. 2. There are many dimensions, structure for the use of protection unit and connection block to meet the new, update, modification, maintenance needs. 3. With four-grade alarm, can use access control, security and other system monitoring the implementation of centralized control or centralized alarm remote interfaces. 4. Contact reed plated with gold or bright tin, flame retardant engineering plastic used. Has a good over-voltage protection and over-current failure to protect. 5. The frame has perfect grounding system. Technical parameters: Working temperature: -5 +40 (degree) Relative humidity: < 85% (30 degrees) Atmospheric pressure: 70 106 (kpa) Storage temperature: -25 - +55 (degrees) Insulation Resistance ≥ 1000MΩ High-voltage protection>3000V (DC)/mm without breakdown,no arc Contact Resistance ≤ 7mΩ between reed wire and terminal into the connection between the contact resistance ≤ 3mΩ Pull strength: ≥ 25N
