Reeling cables
Medium-voltage junction boxes are basic devices used in electrical networks to connect medium-voltage cables, providing a point of interconnection and protection. They are made of a variety of materials, including steel, which offers strength, durability and protection against the elements.They are frequently used when, within a tunnel or industrial plant, it is necessary to carry power supply for long distances via medium-voltage cables
Medium-voltage junction boxes are of the standardized type and suitable for making splices or shunts of M.V. cables with rated voltages of use up to 36 kV.
They can be equipped with an auxiliary box to house the optical fiber.
The octagonal version is made in the standard version from sheet steel and painted appropriately to withstand high stress and weathering. Stainless steel versions can be made upon request.
Installation of junction boxes provides for outdoor environmental conditions max 45°C and min -20°C and a standard degree of protection IP55 that can go up to IP66. Other operating conditions and other degrees of protection can be evaluated upon request.
In addition, it is possible to request the ATEX certified version to be installed in explosion hazard environments, in area classified Group I category M2 (mine) and in surface installations Group II 2GD with protection level Gb, complying with international IEC and European standards, as well as the ATEX 2014/34/EU directive.
Installation of ATEX junction boxes provides for outdoor environmental conditions max 50°C and min -50°C and a standard degree of protection IP65 that can go up to an IP66. Other operating conditions and other degrees of protection can be evaluated upon request.
