Small grouping system of main distribution board

Abstract

Abstract PURPOSE:To eliminate congestion of jumpers and long jumpers so as to improve the performance of work and also to constitute the terminal capacity of a main distribution board module in matching with the circumstance of an exchange side by constituting the main distribution board in the unit of modules. CONSTITUTION:A line side cable l1 is connected to one terminal side of an arrester spring terminal AKR and connected to a vertical terminal V through the other end of the AKR. On the other hand, a horizontal terminal H is connected to a network (not shown in figure) of an exchange directly by an intra-office cable l2. In connecting the line side cable l1 to the network terminal of the exchange, each vertical terminal V and each horizontal teminal H are connected in crossing by a jumper JP at main distribution board modules M0-Mn. The terminal capacity of the main distribution board modules M0-Mn is not especially shown in figure but constituted optionally.
