Marine cable markers are durable, buoyant devices used to identify and protect underwater electrical cables. They are typically brightly colored and feature reflective surfaces for high visibility in marine environments. These markers help prevent accidental damage from boats, anchors, and other watercraft.

Size: Typically ranges from 50 mm to 300 mm in diameter.

Grade: Marine-grade materials compliant with IEC, ISO, and ASTM standards.

Viscosity: N/A (not applicable for solid markers).

Buoyancy: High buoyancy, designed to float in seawater with positive buoyancy.

Material: UV-resistant polyethylene (PE), polyurethane (PU), or other marine-grade polymers.

Color: High-visibility colors (orange, yellow, or red) with reflective strips.

Temperature Range: -30°C to +70°C.

Electrical Properties: Insulating materials with dielectric strength as per marine electrical standards.

Weight: Lightweight, typically 0.5 kg to 5 kg depending on size.

Certifications: Compliant with SOLAS, IMO, and other maritime safety regulations.

Marine Cable Markers and Marine Electrical products typically comply with maritime standards such as IEC 60092, IEEE 45, and ABS (American Bureau of Shipping) requirements. Always verify with the manufacturer for specific certifications.
