    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.

    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.
