Introduction
Product Overview
The European-style cable distribution box is a piece of equipment that has been widely used in recent years for cable-based projects in power distribution networks. Its main features include bi-directional doors and the use of insulated bushings as connections to the busbars. This design offers several significant advantages, such as a compact footprint, clear cable arrangement, and the ability to avoid large-span crossings for three-core cables. Typically, it employs bolted connection cable joints rated for 630A, enabling us to provide satisfactory technical solutions tailored to meet the diverse requirements of various users. This product is widely applicable to 10kV cable distribution networks—including ring-main distribution systems—in urban industrial parks, residential communities, commercial centers, mining areas, and large enterprises in industries such as steel, automotive, petroleum, chemical, and cement, as well as other similar settings. It represents an ideal choice for upgrading urban power grids.
