Its main features are two-way opening and the use of butt sleeves as connecting busbars. It has small length, clear cable arrangement, and three-core cables. There are significant advantages such as no need for long-span crossovers. The cable connector used complies with DIN47636 standard. Generally, bolt-fixed cable joints with a rated current of 630A are used.
