LS3SU Watertight Shipboard Cable

Product Overview

LS3SU Watertight Shipboard Cable is a shielded multi-triad marine cable for shipboard power, control, communication and 400 Hz circuits. The common LS3SU construction uses stranded copper conductors, cross-linked polyethylene insulation, individually shielded triads and a cross-linked polyolefin jacket. It is specified where screened circuits and marine environmental protection are required. LS3SU is a construction designation, not one universal size: triad count, conductor size, jacket dimensions, voltage and qualification depend on the ordered design.

Construction

Element	Typical reference
Conductors	Stranded copper; common public references use 18 AWG triad conductors
Insulation	Cross-linked polyethylene (XLPE)
Assembly	Three conductors form each triad; shielded triads are cabled consecutively with fillers and binder tape
Shield	Braided copper shield around each triad; LS3SUS variants may add an overall shield
Jacket	Cross-linked polyolefin (XLPO), with surface marking

Applications

Shipboard combat systems, interior communications, lighting, control and power circuits where shielded 400 Hz service is required. Confirm watertight construction, flexing, routing and fire/smoke requirements for the vessel installation.

Specifications

Parameter	Reference
Triads	Common public construction: 3 to 44 shielded triads
Service	Typically non-flexing shipboard service; confirm exact installation duty
Dimensions	Jacket thickness, outside diameter and weight vary by triad count and LS3SU/LS3SUS construction
Voltage and tests	Confirm exact rating and qualification on the project datasheet

Standards

Common public reference: MIL-C-24643/35. Confirm the exact revision, qualification, watertight test and approval scope for the supplied cable.
