Product overview
European cable branch box is widely used in recent years in the power distribution network system of the cable engineering equipment. Its main feature is the two-way door, the use of insulated through-wall pipe as a connecting busbar, with a small length, clear cable arrangement, three-core cable without large-span cross and other significant advantages. Generally, the rated current 630A bolt-fixed cable connector is adopted, which can provide satisfactory technical solutions for various user requirements. The product is widely used in urban industrial parks, urban residential areas, urban commercial centers, mining areas and steel, automobiles, petroleum, chemical, cement and other large enterprises and other occasions of the 10KV cable distribution network system in the ring network connection distribution network, is the ideal equipment for urban network transformation.
