Electrical Insulation Tape Tesa H5398835 — PVC 10 m × 15 mm, 5000 V, blue

Tesa electrical insulation tape H5398835 is a blue PVC adhesive tape designed for insulating electrical connections and providing basic protection against short circuits in household and light industrial environments. The tape is 10 m long and 15 mm wide, formulated to insulate conductors at voltages up to 5000 V. Its flexible PVC backing and adhesive layer allow it to conform to irregular shapes and create a protective covering for wires, splices and terminals, as well as for colour-coding circuits.

Advantages

The PVC construction combines electrical insulation properties with mechanical flexibility to wrap around cables and connectors easily. The adhesive provides reliable tack and holds layers together under normal indoor conditions. Compact roll dimensions make the tape convenient for storage and on-the-go use, while the blue colour supports visual identification and circuit labelling. The rated dielectric performance up to 5000 V makes it suitable for many low- and medium-voltage maintenance and repair tasks.

Suitable for

• Insulating wires and cable splices
• Covering terminals and connectors
• Colour-coding circuits and wiring runs
• Basic protection against short circuits in household and light industrial applications

Key specifications

• Material: PVC backing with pressure-sensitive adhesive
• Length: 10 m
• Width: 15 mm
• Rated dielectric performance: up to 5000 V
• Colour: blue
• Flexible and conformable for irregular shapes

How to use

Ensure surfaces are clean, dry and free of oil or dust before applying the tape. Start wrapping at least one full turn over the conductor or splice, stretching slightly while overlapping each wrap by approximately half the tape width to form a continuous insulating layer. Continue wrapping until the damaged area or connector is fully covered and press the tape to ensure adhesion. For multiple layers, repeat the process to achieve the necessary thickness for added insulation.

Usage recommendations

Use this tape for indoor electrical maintenance and light repair tasks. Avoid prolonged exposure to direct sunlight, solvents or high temperatures that can degrade PVC and adhesive performance. For high-voltage or critical safety applications, consult applicable regulations and use appropriate certified insulating materials.
