Ring Main Unit Cable Branch Box, 12/24kV Outdoor Electric Meter Box

12/24kV Outdoor Ring Main Unit Cable Branch Box - Distribution Metering Box

Product Overview | DFT6-12/24 Series Cable Branch Box

The DFT6-12/24 Series Cable Branch Box is a new generation of outdoor power supply equipment designed for 12kV and 24kV power network cable systems. It is engineered for power acceptance and distribution, providing reliable cable connection, branching, and transfer functions in outdoor environments.

With a compact structure and aesthetically appealing enclosure, this ring main unit (RMU) cable branch box is especially suitable for locations with limited installation area and high environmental requirements, including:

City streets
Residential areas
High-rise buildings
Airports
Wharfs / ports

Key Applications

The DFT6-12/24 series is used for:

Connecting
Shunting / branching
Cable circuit continuation
Transferring cable circuits outdoors

Optional: Wooden board inside the case enclosure - available upon customer request.

Service Conditions (Normal Operating Environment)

This outdoor distribution metering box is designed to operate reliably under the following conditions:

Parameter	Value
Altitude	≤ 1000m above sea level
