High-density Main Distribution Frames,High Density Main Distribution Frames,China Main Distribution

High density and large capacity: 2600mm high for each vertical column with the capacity up to 1200 lines, or 2200mm high with the capacity up to 1000 lines.
Double-side installation for modules: CW LSA Disconnection modules can be installed in each horizontal column and Terminal modules in each vertical column, which are connected respectively to the internal and subscriber lines with jumpers in between.
Reliable protection: The over-voltage & over-current protection performance is compatible with the secondary protective circuits of multiple specifications of switches to ensure the switch? primary protection.
Modularized frame structure: Anodic oxidized high-intensity aluminum profiles free the installation from drilling.
Easy operation & maintenance: All operations, including the termination of internal & subscriber lines, testing, alarm system observation and troubleshooting, are done in the front face; the maintenance and testing of a line will not affect other lines.
transmission: All technical indices in the frequency range of 10KHz~1.2MHz comply with the relevant industry standards.
