Tenacious GT7 White Electrical Tape – 19mm x 20m
Create clean, visible and professionally organised cable systems with Tenacious GT7 White Electrical Tape.
GT7 is a premium PVC electrical insulation tape designed for cable insulation, harnessing, bundling, identification, abrasion protection and general electrical maintenance. The white colour provides clear contrast against black cable, dark equipment racks and production infrastructure, making it particularly useful for cable identification, temporary labelling and organised technical inventory.
Manufactured with a thick 0.18mm lead-free, high-grade polymeric PVC backing, GT7 offers a more substantial construction than many lightweight general-purpose electrical tapes. It combines this flexible backing with a high-performance, cross-linked solvent-based rubber-resin adhesive for strong adhesion and dependable conformity around cables, connections and irregular shapes.
Supplied in a practical 19mm width and 20-metre roll, Tenacious GT7 White Electrical Tape is suited to electricians, production technicians, theatres, audiovisual suppliers, film and television departments, venues, schools, workshops and touring crews.
Designed for Electrical Insulation and Cable Protection
GT7 is designed as a professional PVC electrical insulation tape rather than a general-purpose packaging, floor-securing or decorative tape.
Its flexible backing allows it to wrap around appropriately prepared cables, cable looms, harnesses and compatible electrical components. The adhesive helps maintain a secure wrap while the PVC backing provides an additional protective layer.
Potential applications include:
- Electrical cable insulation
- Cable harnessing and bundling
- Circuit and cable identification
- Protecting suitable cable terminations
- Supplementary abrasion protection
- General electrical maintenance
- Marking components and equipment
- Temporary workshop identification
- Automotive electrical work
- Marine electrical applications
- Industrial cable management
- Production-equipment wiring
Electrical tape should always be selected according to the voltage, cable, equipment, environment and applicable electrical requirements.
GT7 should not be used to conceal a damaged conductor, replace a required mechanical repair or return unsafe equipment to service without proper assessment.
Thick 0.18mm Polymeric PVC Backing
One of the key features of Tenacious GT7 is its 0.18mm thick lead-free polymeric PVC backing. The added thickness provides a substantial tape layer while retaining the flexibility required for wrapping cables and irregular shapes.
This construction can be useful around:
- Cable jackets
- Electrical harnesses
- Equipment wiring
- Irregular connections
- Curved components
- Cable looms
- Suitable terminations
- Automotive wiring
- Marine electrical systems
- Production equipment
Tenacious describes the backing as flame retardant and self-extinguishing. It is also identified as RoHS compliant.
The tape’s thickness does not remove the need for correct overlap, controlled application tension, suitable surface preparation or inspection of the completed work.
Strong Cross-Linked Rubber-Resin Adhesive
GT7 uses a high-performance, cross-linked solvent-based rubber-resin adhesive. This adhesive system is designed to provide strong adhesion while allowing the tape to conform around cables, connections and irregular surfaces.
Potential advantages include:
- Secure wrapping around suitable cables
- Good contact across curved surfaces
- Strong cable bundling
- Reduced loose edges
- Practical longer-term installations
- Reliable workshop and maintenance use
- Firm adhesion to compatible surfaces
The adhesive system is described by Tenacious as non-corrosive and long lasting. The manufacturer also identifies resistance to abrasion, UV, alkalis, acids and corrosion as part of GT7’s performance in demanding electrical environments.
Actual performance will depend on the substrate, installation method, environmental exposure, temperature, contamination and service conditions. Suitability should be confirmed under realistic working conditions.
Snap-Back Memory for a Tighter Wrap
Tenacious promotes GT7’s snap-back memory as one of the characteristics that differentiates it from lighter electrical tapes. The tape stretches during controlled application and then recovers, helping tighten the completed wrap around the cable or connection.
This may help technicians achieve:
- Neater cable wrapping
- Firm harnessing
- Close conformity around connections
- Consistent overlap
- Reduced loose edges
- Organised cable assemblies
- A professional finished appearance
The tape should not be overstretched. Excessive tension can place pressure on cables and terminations and may cause the tape to contract or lift after application.
Use only enough tension to create a smooth, conforming wrap. Finish the final section with reduced tension and press the end down firmly.
White Colour for Identification and Organisation
White electrical tape offers strong visual contrast against black cable, dark equipment and technical infrastructure.
This makes it useful for:
- Cable identification
- Temporary handwritten labels
- Marking cable destinations
- Identifying equipment groups
- Separating production departments
- Marking tested or prepared equipment
- Labelling technical workboxes
- Identifying cable lengths
- Organising equipment racks
- Highlighting control or connection points
The white surface may be written on with a suitable permanent marker, although the selected pen and ink should be tested first.
White tape is highly visible, but it should not be used as a substitute for permanent engraved labels, heat-shrink identification or required regulatory markings where those methods are necessary.
Any colour-coding system should be documented and communicated to technicians. Electrical conductor identification must follow applicable standards, equipment instructions and workplace procedures rather than an informal colour system.
Clear Identification in Live Production Environments
The white colour is particularly useful across live production, where much of the equipment, cabling and infrastructure is black.
Potential production uses include:
- Labelling cable destinations
- Identifying feeder or equipment groups
- Marking cable lengths
- Identifying production departments
- Labelling AV equipment
- Marking rack wiring
- Separating touring packages
- Identifying tested stock
- Marking equipment allocated to different stages
- Creating temporary workshop labels
Unlike black electrical tape, which blends into dark cables, white GT7 can remain easy to locate in backstage areas, equipment racks and dim technical environments.
Where the tape must remain visually discreet within the audience’s view or camera frame, black electrical tape may be more appropriate.
Flame-Retardant and Self-Extinguishing Construction
Tenacious identifies GT7 as flame retardant and self-extinguishing. These properties provide additional performance compared with ordinary non-rated PVC tapes.
This does not mean GT7 is:
- Fireproof
- A fire barrier
- A replacement for fire-rated cable
- Approved for sealing fire penetrations
- Suitable for sustained direct-flame exposure
- A substitute for a compliant electrical enclosure
- Suitable for wrapping excessively hot components
The complete cable, equipment and installation must still comply with applicable electrical and fire requirements.
Damaged, arcing, melted or overheated electrical equipment should never simply be covered with tape and returned to service.
Thermal Stability to 80°C
Tenacious specifies good thermal stability to 80°C for GT7.
This is best understood as a material-performance characteristic rather than permission to use the tape continuously on every surface operating at 80°C.
Actual performance may be influenced by:
- Exposure duration
- Cable temperature
- Electrical load
- Ambient temperature
- Ventilation
- Surface material
- Application tension
- Adhesive ageing
- Environmental conditions
Do not apply GT7 directly to:
- Heating elements
- Hot lighting fixtures
- Exhaust components
- Uninsulated high-temperature equipment
- Surfaces exceeding the tape’s rating
- Components where wrapping may restrict ventilation
Where elevated temperatures are expected, confirm the suitability of the tape, cable and entire installation.
Good UV and Water Resistance
GT7 provides good UV and water resistance according to Tenacious’s published product information. These characteristics may support appropriate use in automotive, marine, industrial and outdoor technical environments.
Potential applications may include:
- Covered outdoor production equipment
- Festival technical systems
- Automotive wiring
- Marine electrical installations
- Industrial maintenance
- Equipment transported outdoors
- Outdoor cable identification
- Temporary production infrastructure
Water resistance does not make the completed connection waterproof. Moisture may still enter through cable ends, connectors, damaged insulation, incomplete wrapping or surrounding equipment.
Where a certified waterproof or submersible connection is required, use a properly rated connector, enclosure or sealing system.
Abrasion Protection for Suitable Cables
Tenacious identifies abrasion resistance as part of GT7’s durable protective performance.
When correctly applied, GT7 may provide a supplementary protective layer around suitable cables and harnesses exposed to normal handling.
Potential uses include:
- Production cable looms
- Equipment wiring
- Automotive harnesses
- Workshop cable assemblies
- Industrial control wiring
- Equipment racks
- Temporary technical installations
- Internal AV wiring
Electrical tape is not a replacement for conduit, cable glands, protective sleeving, grommets, cable ramps or mechanical protection where those controls are required.
A cable with severely cut, crushed, melted or otherwise compromised insulation should be assessed and repaired or replaced using an approved method.

White provides a practical writing surface and can make temporary labels easy to locate during installation and troubleshooting.
Do not place tape over ventilation openings, safety warnings, serial numbers, test tags or equipment ratings.
Cable Harnessing and Bundling
GT7 is intended for cable harnessing and bundling across electrical, automotive, marine and industrial applications.
Its flexible PVC backing can follow cable bundles, while the adhesive and memory effect help form a firm wrap.
When bundling cables:
- Confirm the cables are suitable for bundling.
- Avoid excessive tension.
- Do not create sharp bends.
- Keep the bundle clear of moving parts.
- Preserve access to required labels.
- Do not cover damaged insulation.
- Consider heat dissipation.
- Inspect the completed assembly before use.
Bundling multiple loaded cables can affect heat dissipation. Cable ratings, electrical load, ambient temperature and installation conditions must still be considered.
Automotive and Marine Applications
Tenacious identifies automotive and marine work among GT7’s key markets.
Potential applications may include:
- Cable harnessing
- Wiring identification
- Supplementary abrasion protection
- General electrical maintenance
- Bundling low-voltage wiring
