7. Structural Description
If the cable distribution box cannot be placed due to site limitations, it can be directly combined by cable connectors to form multi-circuit cable branching (no need for busbars, see examples for connection methods) and placed in a cable trench or other locations. Example 1: Four-way incoming and outgoing lines (2×600A+2×200A)
Each group consists of two T-II type cable connectors, two sealing connectors and one intermediate connection head. T-II type cable connector (200A) is connected with a sealed cable connector (the other side is connected with a full-insulation metal oxide arrester). See the following figure for dimensions:
Example 2: Three-way incoming and outgoing lines (3×600A)
Each group consists of three T-type cable connectors and two intermediate connection heads. See the following figure for dimensions and examples:
Note: Cable branching can be arbitrarily expanded or reduced according to needs, and can be placed outside the box body or directly buried in the cable trench.
