3M HDCW-110/30-250 Manguito de reparación termorretráctil, negro, 110 mm expandido, 30 mm recuperado, 250 mm de longitud 7000061436

Damaged cable sheaths expose conductors to moisture, corrosion, and mechanical wear, leading to premature failure and safety hazards. The 3M HDCW-110/30-250 repair sleeve provides a permanent, watertight seal for cable jackets with diameters from 30 mm up to 110 mm, restoring insulation integrity without replacing the entire cable.

Who is it for

Maintenance technicians, electricians, and network installers who need to repair damaged cable jackets in industrial, outdoor, or underground environments. It is suitable for low-voltage power cables, telecommunication lines, and other round cables requiring reliable environmental sealing.

Main features

• Cross-linked polyolefin construction with hot-melt adhesive lining creates a moisture-proof barrier.
• High shrink ratio of approximately 3.5:1 allows the sleeve to conform tightly over irregular cable shapes and connectors.
• Expanded diameter of 110 mm and recovered diameter of 30 mm accommodate a wide range of cable sizes.
• Excellent resistance to UV radiation, abrasion, and impact for long-term outdoor durability.
• Operating temperature range from -55°C to +110°C, with a minimum shrink temperature of 120°C.
• Dielectric strength greater than 15 kV/mm provides reliable electrical insulation up to 1 kV.
• Black colour blends with most cable jackets and offers additional UV protection.
