Interlocked socket-outlets (M125) in marine-grade aluminium with fuse-holder for wall-mounting IP66/IP67/IP69
Product details
The wide area of Palermo Marina Yachting (30.000sqm), hosted by the Palermo Trapezoidal harbour, is electrified by interlocked sockets in aluminium by Palazzoli.
1. Environmental risks
- Corrosion: exposure to salinity accelerates the corrosion of electrical components, reducing the insulation and increasing the risk of faults and short-circuits.
- Humidity and infiltrations: an elevate moisture and the possibility of water infiltration into the electrical devices can be the reason of electricity dispersion, faults and short circuits.
- Extreme weather conditions: strong winds, storm surges, heavy rain and lightning can damage the electrical infrastructure and increase the risk of blackout or fires.
2. Electrical risks
- Electrical discharge: the combination of electricity and humid marine environment increases the risk of direct or indirect contact with live parts.
- Short circuits and overloads: very high electrical charges and sudden changes in voltage can cause overloads to the system, causing breakdowns and fires.
- Atmospheric Discharge: harbours are highly exposed to thunderbolts, and this can cause important damages to the electrical devices that are not correctly protected.
3. Operative and mechanical risks
- Interferences with heavy machinery: the presence of cranes, ships and other heavy machinery can cause accidental impacts on electrical cables and switchboards.
- Difficult maintenance: limited accessibility of certain areas and environmental conditions make maintenance and repair operations very complicated.
- Presence of flammable material: fire risk is amplified by the presence of fuels and combustible materials typical of a harbour.
4. Risks to the safety of people
- Electrocution in humid environments: the combination of water and electricity increases the risk of electrocution for workers.
Risk control
- Usage of electrical components with high IP protection level (IP66/IP67/IP69).
- Installation of corrosion protection systems, such as resistant materials and anti-corrosion coatings.
- Implementation of surge and lightning protections.
- Regular maintenance and periodic checks of electrical equipment.
- Personnel training for safe management of the plant.
ALUPRES: The solution
ALUPRES interlocked sockets by Palazzoli represent the ideal solution for the electrification of harbours, ensuring safety, reliability, and resistance in extreme environments. Made of marine aluminium alloy for heavy duty usage, these sockets provide a higher protection against corrosion caused by salinity and atmospheric agents.
Thanks to anti-corrosion surface treatments, ALUPRES ensures a long operative life, even in the presence of aggressive chemical agents that are typical of harbours. The system is available in the versions from 16 A to 250 A, with options of magnetothermal switch, fuses and DIN guide, adapting perfectly to the installation needs.
The degree protection up to IP69 ensures an excellent resistance to water and dust, making these sockets perfect for the marine environment, where humidity and infiltrations represent a constant risk. Moreover, the core system, a sectional switch of category AC-23A/AC-3, allows a safe operation even with highly inductive loads, thus reducing the risk of overloads and short circuits.
The integration of electrical interlocked sockets prevents wrong manoeuvres, ensuring the safe usage from workers, reducing the risk of electrical shocks and malfunctions. Thanks to robustness and advanced technology, ALUPRES is the perfect solution for harbours and marine environments, responding in a satisfactory way to the challenges of electrical safety of these areas.
