Abstract

Enel Global Infrastructure and Networks is looking for a new design for a sustainable street cabinet (built-in container for the distribution of electricity containing new diagnostic devices and tools) which must have innovative features in design and materials, incorporating the principles of circular economy and sustainability.

The new design must ensure the complete observance of the technical and safety regulations currently in adoption for its use and installation, as well as consider for the dimensions the need to contain all the equipment internally required.

OVERVIEW

The street cabinets constitute electrical infrastructures on the street dedicated to the control of the low voltage electricity grid by Enel's expert workforce.

The technological development of the Enel Group has recently led to a technological evolution of the street cabinet, that it is now defined as SMART, due to the presence inside it of a special terminal block, remote switches and an advanced sensor kit for monitoring electrical and environmental data measurements.

Over six years ago, Enel undertook the transition towards a sustainable business model, with a marked acceleration of decarbonization. In 2016, in line with this decision, Enel extended this approach to all of the Group's businesses by adopting, among other things, the concept of circular economy as a strategic driver. Enel's vision of circular economy is not limited to just the recycling of materials but extends to business activities along the entire value chain, starting from the design and procurement phases up to those of production and end-of-life management: this approach to be truly effective, it must be applied right from the design stage and must guide the design of the new street cabinet.


This challenge provides contribution to the following Sustainable Development Goals (SDGs):

  1. SDG 8: Promote inclusive and sustainable economic growth, employment and decent work for all
  2. SDG 9: Industries, innovation and infrastructure. Build resilient infrastructure, promote sustainable industrialization and foster innovation
  3. SDG 11: Sustainable cities and communities
  4. SGD 12: Responsible consumption and production

For the safety of Enel specialist workforce and third parties such as pedestrians, the cabinet complies with specific safety conditions described later in the document.

THE CHALLENGE

Enel Global Infrastructure and Networks is looking for a new design for a new and sustainable street cabinet (built-in container for the distribution of electricity containing new diagnostic devices and tools) which must have innovative features in design and materials , incorporating the principles of circular economy and sustainability.

The development of the new street cabinet will have to address the following requirements:

  1. To comply with the technical, safety and security requirements currently in adoption by Enel for the external container and its internal components;
  2. To have suitable dimensions for the installation of all components;
  3. To respond to a better integration with the city or rural context where it is installed (possibly with the possibility of foreseeing more variations of its version based on the context);
  4. To incorporate into its design and implement as much as possible, the main principles of circular economy and sustainability;
  5. To promote and valorize the corporate image of Enel and its vision through design;
  6. The solution must provide the possibility to convey messages aimed at various stakeholders of the Company.

TECHNICAL REQUIREMENTS OF STREET CABINET:

The cabinet is used to contain unified LV disconnection terminal blocks or measuring units and electronic communication and control equipment and must provide two compartments segregated in terms of electrical safety and interference between the two types of equipment:

  • one compartment is intended for LV power terminal blocks or measuring units;
  • the other one for electronic communication and control equipment.

The street cabinet must comply with the following characteristics:

  • dimensions compatible with easy installation and correct operation of the internal equipment:
  1. Low Voltage terminal board with the following dimensions mm 470(H) x 430 (W) x 100 (D) and complying with the reference technical standards CEI EN 61439-1, CEI EN 61439-5, IEC 60112 and IEC 60695-11-10; the terminal board may be equipped with a motorized breaker; in this case, the dimensions will be mm 470(H) x 461 (W) x 200 (D);
  2. measuring units:
  3. electronic communication and control equipment with the following dimensions mm 200 x 461 x 150. These dimensions refer only to the devices. The DIN bars deep and the backplane deep have to be added. Compatibility with standard rack 19” 4U will be a plus.
  • to allow the easy installation of n.16 LV cables each with a maximum capacity of 318 A, nominal insulation voltage U0/U = 0,6/1 kV and maximum temperature of the cable lugs of 90° C (K=40°C); cables can be both copper with section up to 95 mm2 or aluminum of section up to 240 mm2;
  • allow the installation of the three-phase electronic meter = 20 kW (semi-direct insertion only with external CTs);
  • allow the installation of 2 Single-Phase Electronic Meter = 10 kW and 1 Three-Phase Electronic Meter = 15 kW;
  • allow the installation of electronic devices and accessories in the dedicated compartment;
  • provide the possibility to access to internal equipment through door or independent doors (one for each compartment for example);
  • provide a protected path for cables between compartments;
  • provide optional shielded slits to allow cooling of the compartments by natural ventilation, in compliance with the IP 34D requirement;
  • possibility of affixing the e-distribution logo label and electrocution warning label on the door;
  • possibility of installing a pin or mechatronic key lock;
  • burglar-proof level II in accordance with EN UNI 1627 standards;
  • any metal components shall be made of stainless steel;
  • unified solution foresees SMC material (thermosetting polyester resin) based on polyester or GRP material (glass reinforced plastic), a different material is allowed;
  • unified solution foresees the gray color RAL 7001, a different color or colors are allowed.
In the design phase, please take into account that any prototype will be subjected to all the type tests required by the technical standards for distribution boards in public network.


For material:

  • The street cabinet is currently made with SMC (thermosetting polyester resin) based on polyester or GRP (reinforced plastic glass); alternative material to this type of resin is allowed as long as it is characterized by superior environmental sustainability. It is desirable, where compatible with current regulations, the use of secondary raw material, in the percentages allowed by the standards, especially as an alternative to the resin currently in use;
  • The material must allow or improve the use, accessibility and safety performance of the cabinet in relation to the work processes in which it is involved.

Provide for the possibility of conveying messages aimed at customers or the various stakeholders of the Company;
  • Possess the requirements of realization and economic feasibility;
  • Integrate the circular perspective into the design in order to ensure the longevity of the asset, favor modularity and therefore the replacement and maintenance of components, as well as the recycling/reuse of the materials of the cabinet at the end of its life. The main drivers of a Circular by design approach concern:
  1. Structure/architecture of the product: Reduce the number of components compared to the main functionalities required and a design that facilitates the removal of hazardous materials;
  2. Components: use long-lasting components and avoid hazardous materials;
  3. Materials: Select recyclable/recycled materials and with low energy intensity as well as minimize the variability of materials used. In the analysis of materials the assessment must be made taking into account regulation IEC62474, REACH (European Union regulation for Registration, Evaluation, Authorisation and Restriction of Chemicals) and RoHS (Restriction of Hazardous Substances, Directive 2002/95/EC);
  4. Design for dismantling: the product must be designed in such a way as to facilitate the dismantling and recovery of all materials at the end of their life.
