DFW Switched Cable Branch Box

Functional Characteristics

It adopts prefabricated, touchable silicone rubber cable terminals that are fully sealed, fully insulated, and maintenance-free, reliably ensuring personal safety.
The structure is compact, with a small and aesthetically pleasing appearance, featuring a double-layer stainless steel body that can last over twenty years.
It allows for regional power outage maintenance without aﬀecting the operation of the main network , thereby reducing the scope of power outages.
It can be equipped with one or multiple SF6 Load Switches. The wiring method is ﬂexible and diverse, with branch outgoing lines capable of reaching up to 8 circuits.
Optional components such as surge protectors, short-circuit fault indicators, and current-limiting fuses are available to meet various user requirements.

Basic Structure

Technical Requirements

◇ The inner side of the brick wall is to be sealed with a 1:3 cement mortar mix and treated for waterprooﬁng.

◇ Beam penetrations should use φ6 concrete operations.

◇ The foundation channel steel must undergo anti-corrosion treatment after fabrication.

◇ After the installation of the branch box is completed, the area around the base should be sealed with cement.

◇ Waterproof measures must be taken at the manhole entrance.

◇ Grounding electrodes should be pre-embedded in the foundation, with grounding resistance meeting the requirements set by the power department.

Ordering Instructions

◇ The product model and any special requirements from the user can provide a one-time diagram.

◇ The standard cross-sections for incoming and outgoing lines and branch cables.

◇ The quantity of optional surge protectors and short-circuit fault indicators.
