Maintenance in compact networks: how to optimize the operation

The rubber glove method, where the electrician intervenes directly in the energized network using insulating gloves and sleeves, requires a safe distance between phases and between phase and ground. In conventional networks, this spacing is wide, facilitating the movement and safe work of the professional. In the compact network, the proximity between the cables (often fixed on the same spacer) drastically reduces the free work zone, increasing the risk of accidental touches and electrical arcs.

One of the main challenges is the positioning of the electrician. Access to components, such as connectors and insulators, is restricted, requiring specialized techniques and tools to temporarily separate the cables and create a safe space for intervention. This maneuver, by itself, is delicate and must be executed with extreme precision so as not to compromise the insulation of adjacent cables or the network structure.

Furthermore, the tools used in conventional maintenance may not be suitable for the compact network. Equipment with thinner profiles, better insulation, and ergonomic design that allows handling in confined spaces is required. The covering and protection of cables and components close to the work point also become more complex and crucial to ensure safety.

The training of the teams is another fundamental point. Electricians need to undergo rigorous and specific training for compact networks, which goes beyond the training for conventional networks. It is necessary to master the new cable separation techniques, the use of special tools, and, above all, have a keen risk perception for the particular conditions of this type of network.

In summary, although the medium voltage compact network is a valuable technical solution for the expansion of electrical networks in urban environments, it imposes a new reality for live-line maintenance. Overcoming safety and operational challenges requires continuous investment in new technologies, suitable tools, and, mainly, in the advanced training and qualification of frontline professionals, ensuring the continuity of power supply with maximum safety.
