Challenge Expiration Date: January 9, 2022
Enel Global Infrastructures and Networks S.r.l. is searching for collaboration partners to provide an instrument or tool able to prepare a cable and automatically install an accessory on medium voltage (MV) lines of the distribution networks of Enel Group Distribution Companies. The device must be able to perform the necessary operations with minimal operator intervention.
In the field, operators prepare cables for repair or accessory installation manually. This can occur in various places such as excavations in the ground, at the base of poles (ground level), or at the top of poles (height reached by a lifting basket). Considering the different locations of installation, we are willing to consider all different types of solutions: a lightweight device, a device capable of reaching certain heights with an instrument capable of meeting all the requirements listed below. The device will have to carry out the necessary operations in the most automated possible way, limiting manual intervention to the minimum necessary in order to minimize possible errors of execution by the operator, increase worker safety and improve ergonomic work conditions.
The described Challenge aims to identify an automated device that shall be used in all countries where Enel has MV distribution networks.
This Challenge provides contribution to the following Sustainable Development Goals (SDGs):
- SDG 8: Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all
- SDG 9: Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation

There are two parts that need to be addressed in the solution: cable preparation and accessory installation.
The preparation of the cable requires the different layers (see the attachment section) to be removed for variable length and thickness depending on the type of cable being processed and according to the installation specifications of the cable accessory (see GSCC015).
About the cable preparation phase:
- Positioning and levelling of the instrument.
- Anchorage of the cable to the instrument.
- Performing the 90° cut of the cable end.
- Identification of the cable structure (type, dimensions...) according to the different typology of cable treated by Enel (see the document attached) by means of an automatic recognition system (e.g. optical). Verification of the data with the database stored in the memory. Alternatively, the machine can carry out a calibration of the thicknesses to be removed on the initial section of the cable (which will then be removed for final preparation).
- Automatic selection/acquisition of the characteristics of the accessory to be installed for each type of operation: if not present in the database, it must be loaded by the operator.
- Removal of the various layers of material, using laser and/or mechanical tools and checking the surfaces (irregularities, residues, etc.). The instrument must be able to remove the various materials of the cable with an accuracy of 0,1 mm for thicknesses and length to ensure that the thicknesses of the insulating, semiconductor and conductor layers are in accordance with the specification.
- Acquisition of detail and assembly images of the surfaces and interfaces between one material and another.
- Data recording: GPS position, environmental conditions, characteristics of accessories and cables, operator identification. The instrument must be equipped with an integrated interface system with the operator (e.g. touch-screen display) and on an external support (smartphone, tablet). It must also be equipped with a non-volatile memory containing the database with the characteristics of the cables and accessories used by Enel.
Processing shall be carried out in such a way as to avoid the entry of dust or other contaminants from the external environment. At the end of each stage of material removal, the instrument shall carry out a surface analysis to check the regularity of the material and remove any residual material.
About the accessory installation phase (performed by an operator):
- Plate for screen connection installation (this phase includes the tape to seal the whole joint and protect the junction of the metallic screen)
- Body parking (preliminary installation of the body on one of the cable to be joint);
- Mechanical connector installation (with the correct installation of fuse break screws);
- Put the sealing compounds to preserve the screws cavity;
- Body positioning.
- Remove the body support.
- Plate for screen connection installation (this phase includes the tape to seal the whole terminal and protect the junction of the metallic screen)
- Mechanical conductor lug installation (with the correct installation of fuse break screws);
- Put the sealing compounds to preserve the screws cavity;
- Installation of the component to control the electric field and main insulating housing;
- Remove the body support if present.
In general, regardless of type, a cable is composed of the following layers of material:
- Outer sheath
- Longitudinal water blocking layer
- Metallic earth screen
- External semiconductor layer (cold peelable or bonded)
- Insulation layer
- Inner semiconductor layer
- Conductor (aluminum or copper)
Enel Global Infrastructures and Networks S.r.l. is looking for an automated solution that is capable of performing reconstruction tasks on medium voltage (MV) cables. These tasks include re-insulation, re-screening, and re-jacketing, thereby ensuring normal operation of the cables. The velocity and the ease of use from the device will be evaluated in a positive way, but these must not influence the component reliability.
Submissions should address the following Solution Requirements.
The proposed solutions must:
- Work with the following types of MV cables with cross-sections from 35 to 630 mm2:
- XLPE insulated cables with reduced and full insulation thickness, with aluminum tape or copper wire screen ;
- HTPE insulated cables with aluminum tape or copper wire screen ;
- EPR insulated cables with copper wire screen ;
- Nice to have: Single-core impregnated paper insulated cables with lead shield;
- Perform terminations, splices and joints;
- MV Terminations: A cable termination could be considered as a device able to provide electric stress control for the cable insulation shield, complete external leakage insulation between conductor and ground, a seal to prevent the entrance of the external environment into the cable providing a proper metallic connection (Lug);
- MV Joint: A cable joint could be considered as two conductors connected through a suitable mechanical connector, then re-insulated, re-screened and re-jacketed with proper material and applied over a suitably prepared surface. Whenever possible, jointing cables is normally avoided. However, splicing is often a necessity;
- Be easy to handle and transportable;
- Size range: as small as possible in order to be easy to handle it manually;
- Weight range: as light as possible in order to be easy to handle it manually. The critical conditions reported on ISO 11228 could be considered as reference;
- Be supplied by the following:
- 12 V DC power supply (either directly or by a 230 V AC/DC converter included in the scope of supply);
- Built-in 12 V DC battery with operating autonomy for at least 6 installations and with power and battery status indicator showing the number of installations remaining to be performed;
- NOTE: 230 V AC power supply or other solutions are accepted for the development phase;
- Be safe for the operator;
- The instrument shall be equipped with intrinsic safety interlocking systems to ensure operator safety at all times; There shall be emergency stop buttons, easily accessible by the operator from every side of the equipment he is working on;
- In addition, a minimum degree of protection of IP 53 must be guaranteed (must be able to operate safely in the rain);
- All working phases must be directly or indirectly monitored (for example with micro-cameras) and must be confirmed by the operator (one by one or also giving cumulative confirmation for all phases);
