Danger High Voltage Tape
OPALUS PACK is a manufacturer of danger high voltage tape for temporary electrical hazard marking during high-voltage maintenance. Made from non-adhesive PE film, the tape carries repeated “DANGER HIGH VOLTAGE” printing to help define restricted areas around substations, transformer yards, switchgear rooms, and power distribution equipment. It is not electrical insulation tape. Its purpose is visual warning, temporary isolation, and access boundary control where clear site communication is required.
- Standard Size: 75 mm x 300 m, 3 in x 1000 ft
- Color Options: Red/Black, Red/White
- Material: Non-adhesive PE film
- Thickness: 0.03 mm – 0.10 mm
- Printing: Repeated DANGER HIGH VOLTAGE text
- Fixing Method: Cable ties, clips, staples, or barrier posts
Product Overview
Danger high voltage tape is used when an energized or potentially hazardous electrical area must be made visible before workers approach it. In maintenance work, the issue is often an unclear temporary boundary after panels, transformers, cable sections, or switchgear units are opened for inspection.
The non-adhesive polyethylene structure is practical for electrical service teams because it can be fixed to fences, temporary posts, frames, or barricade stands without sticking to cabinets or equipment surfaces. After the work area is released, the tape removes cleanly without adhesive residue.
Roll length selection depends on the site. A 100 m roll suits small equipment checks, while 300 m or 1000 ft rolls are more efficient for substation perimeters, cable routes, or wider distribution areas. The 0.03 mm – 0.10 mm thickness range balances light handling with better tear resistance during outdoor setup.
Because high-voltage work may require both a Danger signal word and stricter physical controls, review when danger tape is required instead of caution tape before approving the boundary system.
Benefits
- Clear high-voltage recognition Repeated warning text keeps the message visible along long electrical maintenance boundaries.
- Non-adhesive and residue-free The PE film can be tied, clipped, stapled, or wrapped without leaving glue on equipment surfaces.
- Suitable for temporary electrical isolation It helps create a temporary electrical safety barrier around areas limited to trained or authorized personnel.
- Outdoor-ready visibility Weather-resistant PE film and durable printing support short-term outdoor use around substations.
- Practical color selection Red/Black provides stronger danger recognition, while Red/White is useful for restricted maintenance boundary marking.
- Fast site handling Rolls are light enough to carry, cut, reposition, and remove during inspection, repair, or emergency control.
What Makes Non-Adhesive PE Warning Tape Practical for High Voltage Maintenance Areas?
A high voltage warning tape used near electrical equipment should not interfere with the equipment itself. Adhesive-backed products may leave residue or require cleaning after removal. Non-adhesive PE warning tape avoids that issue and can be repositioned as the work zone changes. This is useful in substations where teams may inspect different panels, transformers, or switchgear sections during the same maintenance period.

Applications
- Substation maintenance zones requiring temporary access boundaries
- Transformer yards during inspection, repair, testing, or service work
- Switchgear rooms where energized areas need visual separation
- Power distribution areas requiring restricted access marking
- High-voltage cable maintenance routes needing a continuous warning line
- Electrical testing and commissioning areas requiring temporary hazard identification
- Utility service areas where red warning boundaries help reduce accidental entry
How Should This Tape Be Fixed Around Energized Electrical Areas?
This tape should be installed as a visible boundary, not attached directly to live electrical parts. Most teams fix it to posts, fences, guardrails, or barricade stands with cable ties, clips, staples, or wrapping methods. For long runs, keep the printed side facing the approach direction. In windy areas, closer fixing intervals help prevent twisting and keep the warning message readable.
FAQ
Is Danger High Voltage Tape the same as electrical insulation tape?
No. It is for visual warning and restricted area control, not insulation, cable wrapping, or electrical protection.
Can this tape be used outdoors around substations?
Yes. The PE film and printed text suit temporary outdoor use around substations, transformer yards, and distribution areas.
What colors are commonly used for high-voltage warning areas?
Red/Black gives strong danger recognition. Red/White is often selected for restricted maintenance boundary marking.
How do I choose roll length?
For small equipment checks, 100 m may be enough. For longer substation or cable maintenance boundaries, 300 m or 1000 ft rolls are usually more practical.
