1. Electrical heat shrink tape works by first applying to and then heating to cause shrinkage around cable or connector that it insulates electrically with one piece of tape.
2. The shrink wrap tape seals away moisture and at the same time physically hardens up to protect any kind of wire.
3. Cylindrical heat shrink wrapping tape is suitable for use with mains voltages ranging from 1kV to 36kV without any risk.
Over the years power system’s main parts undergo deterioration due to aging and external environmental impacts. In particular, conductors and contacts might be damaged by moisture, dust, and other factors causing loss of insulation, reduction of seal tightness, and increase of possibilities of leaks, short circuits, and equipment failures.
Existing protection solutions are not sufficient to address simultaneously the three main functions - insulation, sealing, mechanical protection - at an optimum level.
Solution:
The shrinkage of cable insulation tubing by heat shrinkage ensures excellent contact, which gives a uniform and stable covering that protects against any insulation breakdown. The cable heatshrinkable tape has very good insulation against moisture, sealing properties, and mechanical protection that prevents the intrusion of external moisture and contaminants; hence, it enhances the stability of the electrical system and meets the long-term safety protection requirements of 1kV to 36kV systems.
Product Introduction:
Electrical heat-shrinkable sealing tape, or heat-shrink wrap, is a type of sealing material specially developed for insulation that ensures a lasting protection from high-voltage electricity components. Once heat-shrunk, it snugly wraps around the cables, wires, and connectors that it is put on, creating an insulating continuous protective layer.
This kind of tape not only acts like a shield against electricity but also against water, and at the same time, it provides mechanical protection and resists any environmental damage. As a result, the use of electrical leakage, short circuits, and damage from outside the system is efficiently prevented. Such a tape is commonly used from 1kV up to 36kV voltage levels to power systems, in cable joints, and in electrical insulating protection in the industrial sector.

Advantages of Wrap Around Heat Shrink Tape:
1. Insulation and Protection:
On heating, the product strongly sticks to the surface of electric components, forming a steady, insulating protective coat. Thus, the dielectric qualities are boosted dramatically without the possibility of any electrical fault through leakage.
2. Convenient Installation:
Mechanically we shrink the high temperature heat shrink tape with heat, and no elaborate instruments or tools are needed for this process. It can be used easily on various types of structures and in different places where joints are required.
3. Environmental Adaptability:
Electrical wraps made from electrical wrapping tape are highly resistant to moisture, have anti-tracking characteristics, and are aging resistant, so they can always provide stable protective performance in different indoor and outdoor environments.
4. Temperature Resistance:
Our high temperature heat shrink tape works in temperatures from -55℃ to 105℃. It is still highly reliable at such low and high temperatures.
Applications of Electrical Wrapping Tape:
This substance is mostly used in industrial electric systems as insulation and sealing material for electric connection points in engines, pumps, motor-driven devices, and transporting systems. In transport and automotive industries it is employed for providing insulation on vehicles' wiring harnesses and electrical connectors, and in aviation for insulating the electronic circuits. Thanks to its excellent resistance to heat, vibration and good adaptability to diverse environments, it offers a long-term reliable insulation and sealing protection of the circuits that run through vehicle, rail transport, and aerospace facilities that are considered very important.
