Insulation Tape Blue Line TTE701S3-0019-20 — blue, 19 mm × 20 m

Blue Line insulation tape TTE701S3-0019-20 is a blue electrical insulating tape with a 19 mm width and 20 m roll length designed for insulating, bundling and marking electrical wires and cables. The tape is made for general electrical maintenance, repairs and DIY tasks where a narrow, flexible adhesive tape is required. Its color allows quick identification and color-coding of circuits and cable runs.

Advantages

The tape provides reliable electrical insulation for low-voltage applications and protection against minor abrasion. Its flexible backing conforms to irregular surfaces and tight corners, and the adhesive offers good immediate tack for easy wrapping. Compact roll size delivers convenience for storage and on-site portability while the consistent width and thickness ensure uniform coverage and predictable performance.

Suitable for

• Insulating and repairing household electrical wiring
• Bundling and securing cable harnesses
• Color-coding circuits, panels and cable runs
• Light maintenance work and DIY electrical projects
• Taping joints in temporary or prototype installations

Key specifications

• Color: blue
• Width: 19 mm
• Roll length: 20 m
• Flexible backing for conformability
• Pressure-sensitive adhesive for immediate tack
• Intended for low-voltage electrical insulation and identification

How to use

Ensure surfaces are clean, dry and free of oils or dust before applying the tape. Measure and cut the required length, then wrap the tape around the conductor or bundle with slight overlap to create continuous coverage; press firmly to activate the adhesive. For marking or color-coding, apply a short band around the cable or a longer wrap for more visible identification. Avoid stretching the tape excessively during application to maintain insulation properties.

Usage recommendations

Store the roll in a cool, dry place away from direct sunlight. Use this tape for low-voltage and general-purpose electrical tasks; do not use as a substitute for heat-shrink tubing or where long-term resistance to high temperatures, moisture ingress or chemical exposure is required. Replace damaged or degraded tape to preserve insulation integrity.
