Detailed description

Designed for demanding marine electrical applications, the 35mm² Hi Flex cable in red offers high current capacity for high-power systems on board. Its 35mm² cross-section is suitable for battery connections, power converter supply lines, and power-hungry equipment such as bow thrusters and medium-power windlasses.

Flexibility and Installation

The "HI FLEX" designation highlights the enhanced flexibility of this cable, a significant advantage in marine environments where cable runs are often constrained and tortuous. This flexibility simplifies installation and reduces mechanical stress on connections, particularly in confined spaces, compared to similarly sized but less flexible cables. The Hi Flex KA351 cable is manufactured in Italy, ensuring compliance with European production standards for this type of component essential to shipboard electrical infrastructure.

Applications and Technical Positioning

While smaller cross-sections such as 10mm² or 16mm² are commonly used for secondary circuits or moderate-power equipment, the 35mm² of the Hi Flex KA351 cable positions it as a choice for main lines requiring significant current-carrying capacity. It avoids the installation constraints of 50mm² or larger cables, typically reserved for very high-power consumers or inter-battery connections in large battery banks. This red cable is conventionally used for positive poles in 12V or 24V DC systems, in line with marine wiring practices.

Expert opinion

« 35mm² Hi Flex cable: the flexible option for marine power »

The 35mm² cable is a fundamental component for electrical distribution aboard vessels. The Hi Flex KA351 model stands out for its flexibility, a major advantage when routing through often cramped technical compartments. This feature reduces copper fatigue from vibrations and simplifies passage through conduits or behind bulkheads, a critical factor for the longevity and safety of installations. As an installer, I prefer this type of cable for direct connections between service batteries and couplers, or for powering mid-range converters (< 2000W) where minimal voltage drop is required. It is also suitable for small bow thrusters or windlasses up to approximately 1000-1200W, depending on cable length. For high-power applications, such as large thrusters, combined chargers/converters over 3000W, or extensive battery banks, sections of 50mm² or more should be used to prevent overheating or efficiency loss. The red color is conventional for the positive pole, aiding identification and maintenance.
