Insulating Electrical Tape Tesa H5398820 — PVC 10 m × 15 mm, rated for 5000 V, red

Tesa insulating electrical tape H5398820 is a PVC-based adhesive tape designed for electrical insulation and basic cable protection. The tape is 10 meters long and 15 mm wide, with dielectric properties rated for use up to 5000 V. Its red colour supports identification and colour-coding of wires, while the vinyl material provides flexibility for wrapping around connectors and irregular shapes in domestic, workshop and light industrial settings.

Advantages

The PVC construction ensures good mechanical strength and resistance to abrasion, while the adhesive backing provides secure adhesion to common cable insulation materials. Rated for 5000 V dielectric protection, the tape offers reliable insulation for low- and medium-voltage tasks within its specified limits. Its compact roll size and 15 mm width make it suitable for precise work, colour-coding and quick repairs without bulky application tools.

Suitable for

• Insulating and wrapping wires and cable joints in domestic installations
• Colour-coding and marking of electrical conductors and harnesses
• Minor insulation repairs and temporary fixes in workshops
• Bundling and securing small cable groups
• Protecting connectors and terminals from abrasion and short circuits within rated voltage

Key specifications

• Material: PVC (polyvinyl chloride)
• Length: 10 m
• Width: 15 mm
• Dielectric rating: suitable for insulation up to 5000 V
• Colour: red
• Form: adhesive roll for manual application

How to use

Clean and dry the surface of cables or insulation before application to ensure optimal adhesion. Unwind the tape and wrap it tightly around the conductor or joint with slight overlap between turns, maintaining tension to eliminate air gaps. For best dielectric performance, cover the exposed area fully and extend the wrap onto adjacent insulation by several centimetres. Cut or tear the tape to finish and press the end down to secure the bond.

Usage recommendations

Use this tape only within its rated voltage and temperature limits. Do not rely on it for permanent protection in high-voltage or outdoor environments without verifying environmental suitability. For critical or permanent installations, consult applicable electrical standards and consider professional-grade insulating materials designed for the specific installation conditions.
