Capillary Rise of Moisture in Electrical Conductors.

Capillary moisture rise in electrical conductors is a physical phenomenon that occurs when water molecules ascend through small gaps or pores within materials, despite gravity. This effect is particularly evident in porous materials such as fabrics or granular media, but it can also occur in electrical cables, especially if they are not fully sealed or if the outer sheath is damaged.

In essence, this occurs when moisture that has penetrated or is present inside the cables flows along them, reaching the connectors and ultimately the end device (a lamp, an electric motor, etc.). At best, this reduces system performance, but it often significantly shortens its service life, compromising the operation of the entire installation.

In electrical cables, water can infiltrate through damaged sheaths or non-hermetic joints, then rise by capillarity along the internal conductors, reaching connectors and other electronic components.

This can lead to several problems:

• Corrosion: Water and moisture can cause corrosion of metal contacts, reducing their efficiency and lifespan.
• Short circuits: Moisture can facilitate the formation of conductive paths between adjacent wires, leading to short circuits.
• Insulation degradation: Moisture can degrade insulating materials, reducing the cable’s dielectric effectiveness.
• Damage to the luminaire: As it rises through the cables, moisture can irreparably damage luminaires.

The Paguro IP68 connector incorporates an insulating gel that performs several crucial functions:

• Physical barrier: The gel creates a physical barrier inside the connector, preventing the ingress and capillary rise of moisture up to the luminaire, thereby avoiding damage.
• Corrosion protection: The gel protects metal contacts from corrosion, maintaining the integrity of electrical connections.
• Elasticity and adaptability: The gel retains its elasticity and adaptability even after installation, ensuring long-lasting protection even in the presence of cable vibrations or movement.

To prevent the capillarization phenomenon that affects electrical and data connections, you can use Paguro connectors, all IP68 certified, which employ an insulating gel, pre-cast at the factory, inside the junction box.

Paguro IP68 connectors are designed to be waterproof and dustproof and are therefore widely used across a broad range of applications in harsh environments, including outdoor lighting systems, sensors, and civil actuators.
These connectors are particularly useful in demanding environments such as marine settings, where the presence of water—especially saltwater—and corrosive agents can compromise the long-term durability of connections and equipment.
Paguro IP68 connectors are certified to withstand the most severe conditions and are tested to ensure they can maintain performance in any environment.

The insulating gel used in these connectors is a colorless, strictly non-toxic material capable of sealing connections and protecting them from moisture, dust, and other atmospheric agents. The insulating gel fills all the space inside the junction box to completely seal the connection.
Furthermore, the insulating gel used inside the connectors protects against moisture capillarization, extending the life of connected equipment and reducing maintenance costs.

Another advantage of Paguro IP68 connectors with insulating gel is their easy installation. These connectors are designed for quick and simple installation, without requiring special tools or advanced technical skills. In addition, thanks to their compact size and ergonomic shape, they can be installed even in tight or hard-to-reach spaces.

To use Paguro IP68 connectors, you must follow a few simple precautions. First, ensure that the cables used are compatible with the chosen Paguro IP68 connector type; second, follow the manufacturer’s instructions for installing and using the connector itself.

In conclusion, moisture capillarization in cables can be resolved by using Paguro IP68 connectors that employ insulating gel. These connectors are designed to withstand the most severe conditions and can protect connections from moisture, dust, and other atmospheric agents. By following simple installation and usage precautions, Paguro IP68 connectors can ensure a reliable, long-lasting connection, even in extreme environments.
