■European type cable branch box structure diagram
If the cable branch box cannot be placed due to site limitation, it can be directly combined with cable joint to form multiple cable branches (without the need for busbar, the connection method is shown in the following example) and placed in the cable trench or its location.
Example 1: Four-way incoming and outgoing lines
Each phase consists of two European type front joints and two European type rear joints, with one European type connected to butt sleeve in the middle. The end of the European type rear joint is sealed with insulator and semiconductive end cap. The example is shown in the following figure:
Example 2: 2 incoming 3 outgoing
Each phase consists of three European type front joints and two European type rear joints, connected by European type butt sleeve in the middle. The end of the European type rear joint is sealed with insulator and semiconductive end cap. The example is shown in the following figure:
Note: Cable branches can be expanded or reduced as needed, and can be enclosed in a box or buried directly in cable trench.
