Tonful High Voltage Self-Adhesive Rubber Tape Step-by-Step Installation

Proper installation ensures optimal performance and longevity. Follow these simple steps:

01

Ensure the surface is clean and dry.

02

Stretch the tape to 200-300% of its length (or up to 1000% for some tapes) to ensure it fuses properly.

03

Wrap it using a half-lap technique, overlapping each wrap by half the tape’s width, while maintaining constant tension to avoid voids.

04

For low voltage (<600V), use at least 2½ half-lapped layers; for high voltage, follow manufacturer guidelines for layers.

05

Overwrap with vinyl tape to protect from damage and environmental factors.

Allow the tape to fuse over 24 hours, forming a solid mass.

In extremely wet environments, consider adding a small amount of dielectric grease For maximum wire insertion, pre-twist conductors with lineman's pliers In high-vibration applications, secure wires with additional cable ties For underground applications, wrap the connection with self-fusing silicone tape for enhanced protection

Frequently Asked Questions

We have compiled some common questions from our clients. If your question isn’t included here, our customer service is always available to help. We’d love to talk with you.

What Are High Voltage Self-Adhesive Rubber Tapes?

Our High voltage self-adhesive rubber tapes are specialized tapes designed for electrical insulation, particularly in high voltage applications. They seem to be made from rubber materials like silicone or ethylene propylene rubber, offering good insulation and resistance to environmental factors. These tapes are often self-fusing, meaning they bond to themselves when stretched and wrapped, rather than relying on a separate adhesive layer.

What's the Materials and Composition of the high voltage self-adhesive rubber tapes？

The tape’s composition varies based on the rubber material used, which influences its properties and suitability for specific applications. Common materials include:

Ethylene Propylene Rubber (EPR): Known for its excellent electrical properties, weather resistance, and flexibility. Examples include HelaTape Power 810 (HelaTape Power 810), which is halogen-free with outstanding corona, ozone, and UV resistance, ideal for high voltage up to 69 kV.
Silicone Rubber: Offers high temperature resistance and flexibility, often used in military and aerospace applications. For instance, X-Treme Tape is silicone-based, meeting military specifications like A-A-59163 (A-A-59163 INSULATION TAPE), suitable for temperatures from -90°C to 260°C.
Other materials, such as polyisobutylene (PIB), may be used for specific applications, but EPR and silicone are predominant for high voltage insulation.

where to use the High Voltage Self-Adhesive Rubber Tapes?

It’s commonly used in industries like electrical utilities, telecommunications, aerospace, and marine to insulate and protect cables, splices, and connections that operate at high voltages, typically up to 69 kV.

Electrical Insulation: Insulating cable splices, terminations, and connections in high voltage settings, such as substations and distribution systems.
Moisture Sealing: Waterproofing joints and protecting against corrosion in outdoor environments, such as boat and RV hook-ups.
Repair and Maintenance: Repairing leaks in hoses, ducts, and pipes, particularly in harsh conditions like chemical exposure or high humidity.

How do I Comparing tape types ?

Select the appropriate size based on:

The gauge (AWG) of wires being connected
The number of conductors being joined

Considerations for Different Environments

The tape’s performance varies by environment. In production plants with steam and high humidity, self-fusing rubber tapes provide needed moisture protection, often requiring an overwrap with vinyl tape in chemical exposure scenarios to prevent corrosion. For outdoor applications, such as boat and RV hook-ups, X-Treme Tape’s resistance to salt water, UV rays, and fuels makes it ideal, with a recommendation to keep a roll in vehicles for emergency repairs

Conclusion

In summary, High Voltage Self-Adhesive Rubber Tape is a versatile, self-fusing solution for electrical insulation, with detailed application involving stretching, half-lapping, and layering, followed by protective overwrap. Its effectiveness in high voltage and harsh environments makes it indispensable, with variations catering to specific needs based on material (EPR or silicone) and environmental conditions.
