12 / 24KV Outdoor Ring Main Unit Cable Branch Box / Distribution Metering Box
General
DFT6-12/24 Series Cable Branch Box is a new power supply equipment that is designed for coordinating 12/24kV power network cable system for power acceptance and distribution. The series cable branch box has unique structure and beautiful appearance, it especially is suitable for the place that covers small build-up area and has higher requirement in environment such as city street, residence area, high-rise, airport and wharf, etc.
It is used in connecting, shunting, branching, continuing and transferring cable circuit outdoor.
Add wooden board of the case enclosure according to the customer's request.
Service condition
