Insulation Tape K2 B330 — 19 mm x 20 m

K2 B330 insulation tape, 19 mm x 20 m, is a general-purpose electrical tape designed for insulating, bundling and repairing wires and cables. Supplied on a convenient roll, this tape is suitable for temporary or routine electrical maintenance tasks where a narrow-width tape is required. The product is intended for household, workshop and light industrial use, providing a simple solution for wrapping splices, covering exposed conductors and securing connectors.

Advantages

This electrical tape offers consistent thickness and flexibility for easy wrapping around irregular shapes. It adheres cleanly to common cable insulation materials and retains elasticity to maintain a snug fit over time. The narrow 19 mm width enables precise application in confined spaces and on multi-core cable assemblies. The 20 m roll length provides multiple uses from a single roll, reducing the need for frequent replacement during small repairs.

Suitable for

• Insulating exposed conductors and wire splices
• Temporary electrical repairs and maintenance
• Bundling and organising small cable runs
• DIY electrical projects and household fixes
• Marking or colour-coding individual wires (when used with coloured variants)

Key specifications

• Width: 19 mm
• Length: 20 m per roll
• Material type: flexible electrical insulating film
• Primary use: electrical insulation and cable repair
• Form factor: hand-wound roll for manual application

How to use

Clean and dry the surface of the cable or conductor before application. Unwind the required length and wrap the tape with slight overlap, maintaining consistent tension to avoid gaps or air pockets. For splices and joints, start the wrap several centimetres before the splice and finish several centimetres after to ensure full coverage. Trim excess tape with scissors or a utility knife. For best results on live systems, ensure power is switched off and follow local safety regulations.

Usage recommendations

Store rolls in a dry environment away from direct sunlight and heat sources to preserve adhesive performance. Use in dry conditions or on clean surfaces; avoid prolonged exposure to oils and solvents that may reduce adhesion. For permanent or high-voltage insulation needs, use products specifically rated for those applications.
