Overview

The DWF-35 outdoor AC cable branch box is a device that has been widely used in cable projects within power distribution systems in recent years. Its main features include a double-door design and the use of a butt joint sleeve as a connecting busbar. It has advantages such as a compact size, clear cable arrangement, and no need for large-span crossing of three-core cables. The cable joints it uses conform to the DIN47636 standard.

Generally, bolt-fixed cable joints with a rated current of 630A are used.
