Product Overview
The European-style cable distribution box is a piece of equipment widely used in recent years for cable-based projects within power distribution systems. Its key features include bi-directional doors and the use of insulated wall-through bushings as connections for busbars, offering significant advantages such as compact size, clear cable arrangement, and eliminating the need for large-span crossings in three-core cables. Typically equipped with rated current 630A bolted connection cable joints, this device can deliver tailored, highly satisfactory technical solutions to meet a wide range of customer requirements.
Widely applicable to: urban industrial parks, residential communities, city commercial centers, mining areas, and large enterprises such as steel, automotive, petroleum, chemical, and cement industries—as well as other settings—this 10kV cable distribution system is ideal equipment for ring-network-connected distribution networks in urban grid upgrades.
