The story of a major project: bringing the Castelli di Cannero back to life with technology\u2014a lakeside fortress from the early 1400s.<\/p>

The operation began in spring 2018 when the property owner, together with the design firm, involved us in technical assessments to reconcile the need for modern lighting, safety, and energy management systems with the enhancement of the historic site while preserving its architectural identity and environment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A first challenge was the construction of the 400 kW transformer substation, providing power for the lighting systems, water treatment plants, and air conditioning.<\/p>

The transformer substation was designed, adapted, and built respecting the original structure of the Castle. It consists of a medium-voltage panel, low-voltage electrical panels, and a 15000\/400V 400kW transformer. <\/p>

A 100 kW emergency diesel generator with automatic start-up restores power to all essential parts of the island within 12 seconds in the event of a power failure, while two UPS units with a total capacity of 30 kW maintain online power to all sensitive and vital systems.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Detailed design and construction of electrical panels for the reception and museum technology areas, incorporating KNX modules for system management and energy monitoring and metering.<\/p>

Installation of the main infrastructure with underground conduit networks for power cables serving the technology, museum lighting, and scenic lighting systems.

All technical systems are managed and remotely controlled by Siemens equipment (Desigo platform), lighting scenarios use the KNX communication system, and emergency lighting uses Din devices, with 7 static groups complete with backup batteries for online power supply to all emergency lighting, escape routes, and part of the ordinary museum lighting. <\/p>

In collaboration with the construction management and Floss, we developed the design and installation of the distribution system using equipped totems for ordinary lighting with Floss fixtures and emergency lighting with Din equipment.<\/p>

The video surveillance system was installed with CARRIER ultra-high-resolution cameras.<\/p>

The system is supported by a multimode fiber optic communication network and cables for high-humidity environments type UTP CAT.6, BTnet data rack panels, and Wi-Fi system communication cells.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The detailed design of the medium-voltage receiving substation on the mainland is approved.<\/p>

Concurrently with the construction of the structure, agreements are reached with E-Distribuzione, the ABB medium-voltage panel with sulfur hexafluoride circuit breaker is installed, and preparations are made for connecting the underwater cable.<\/p>

Once the receiving facility is equipped with electrical systems, the data infrastructure is also prepared for future connection to the national fiber optic network with panels and equipment for terminating the multimode fiber optic cable for the Castelli connection.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

In September 2024, after careful evaluation of distance, depth, and seabed type, the Prysmian RG7H1OEFE3X50mm+12 fiber underwater cable is selected and ordered.<\/p>

The cable is delivered to us in May 2025, and installation on the lakebed is scheduled for May 23. The highly delicate operation involves us in collaboration with Aedes contractors and Comar, a company specializing in underwater work. <\/p>

Subsequently, medium-voltage and fiber optic terminations are completed, and ground resistance measurements are performed with Equa to ensure safety.<\/p>

On June 9, 2025, the Castelli di Cannero are permanently energized!<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
