European-style cable junction boxes are widely used in cable engineering projects in power distribution networks in recent years. Their main features include bidirectional opening, use of wall bushings as connecting busbars, and significant advantages such as short length, clear cable arrangement, and no need for large-span crossings of three cables. The cable joints used conform to the DIN47636 standard. Generally, bolt-fixed cable joints with a rated current of 630A are used.
