Detailed description

KU04 3x20AWG unjacketed cable is an ETFE-insulated KU / KU-B cable for marine electronics wiring and demanding environments. It uses tinned copper conductors and ETFE insulation suitable for low and high temperatures.

Configuration: 3x20 AWG. Shielding: unshielded. Manufacturer’s rated voltage: 600 Vac / 850 Vdc. Operating temperature: -55 °C to +150 °C. Outer diameter: 3.27 mm.

Onboard, use these cables for control links, signal wiring, or general wiring where thermal resistance, compactness, and jacket durability are priorities. Separate low-signal wiring from power bundles and protect through-hull penetrations.

« KU04 3x20AWG cable: selection and protection for marine installation »

The KU04 3x20AWG unjacketed cable is a fundamental wiring solution for marine integration professionals. Its three-conductor 20 AWG configuration is primarily intended for signaling circuits, low-power power supplies (sensors, small instruments), or non-proprietary data buses requiring maximum flexibility in routing.

In terms of installation, the absence of an outer jacket gives this cable high flexibility, making it easy to route through existing conduits, tight passages, or to create custom harnesses. However, this characteristic requires increased vigilance during deployment. It is imperative to systematically protect it against mechanical abrasion, moisture, and electromagnetic interference. The use of braided sleeving, spiral wrap, or heat-shrink tubing is not only recommended but often essential to ensure the longevity and reliability of the installation in the corrosive and vibrating marine environment.

This type of cable differs from pre-jacketed or shielded solutions due to its cost and versatility as a raw component. It is particularly relevant for repairs where only a specific section of internal wiring needs to be replaced, or for creating custom harnesses where space constraints are critical. It is not, however, suitable for unprotected outdoor applications or for high-power connections where larger gauges and robust jackets are required. Planning for external protection is a key step in its integration.

Frequently Asked Questions

Need help? Contact us

What does the designation '3x20AWG' mean for this cable?

The designation '3x20AWG' indicates that the KU04 cable consists of three internal conductors. Each conductor has a cross-section of 20 AWG (American Wire Gauge). This gauge is typically used for low-power circuits, data transmissions, or control signals where current requirements are not high.

What are the implications of this cable being 'unshielded' in a marine environment?

The fact that the KU04 cable is 'unshielded' means it has no outer protective jacket. This characteristic gives it high flexibility, making it easier to route in tight spaces or conduits. However, it also means the cable must be protected externally, such as with heat-shrink tubing, conduits, or cable glands, to shield it from abrasion, moisture, and marine-specific electromagnetic interference.

How is the KU04 cable sold?

The KU04 cable is sold by the meter. This allows you to order the exact length required for your installation, optimizing use and minimizing waste.

What additional protections are required for this unarmored cable in a marine environment?

Given that the KU04 cable is unarmored, it is essential to provide it with adequate external protection, especially in a marine environment. It is recommended to use heat-shrink tubing, protective conduits, or cable glands to effectively shield it from physical abrasion, moisture exposure, and potential electromagnetic interference.

Is this cable compatible with standard marine connectors and terminal blocks?

Yes, the KU04 3x20AWG cable is designed to be compatible with a wide range of standard connectors and terminal blocks that match 20 AWG wire gauges. Its simple design makes end preparation for crimping or soldering straightforward, ensuring easy integration into existing systems.

À quoi sert Câble KU04 3x20AWG non gainé ?

Câble KU04 3x20AWG non gainé sert au câblage électronique, de commande ou de liaison auxiliaire selon son nombre de conducteurs, sa section et son blindage.
