Outside Plant Copper Cable Termination and Distribution

1 Pair Distribution Box,1 Pair Termination Box

Terminal module connection box, terminal block connection box, CW VX box,1 Pair Distribution Box,1 Pair Termination Box

The terminal block of connection adapts for connecting the distributive wires of external and internal padding. Its construction provides the possibility of conducting the control measurements of the connected chains before both directions. Box provides protection from the environmental effects.

The terminal block of connection consists of housing and cover of rectangular form, and also 5- polar unit of connection, fixed on the housing. Cover is fixed beyond the axis common with the housing; however, it can be isolated from the housing for guaranteeing the convenience in the work due to the squeezed conditions. The introduction of wires is accomplished through the detachable stuffing boxes, which ensure the possibility of applying the wires of different sizes. Fastening wires is accomplished by the metallic screws, located inside the unit of connection.
