3M 7000007286 Scotch 23 19 mm x 9.15 m x 0.76 mm black Etylen-Propylen-Kautschukband HT002001309 content_copy

The 3M Scotch® Self-fusing Rubber Tape 23, type 7000007286, is a specialized insulating tape for electrical applications based on self-fusing EPR (ethylene-propylene rubber). It is used for insulation in low- and high-voltage applications, as well as for sealing electrical connections up to 69 kV. The tape features high conformability and an elongation of up to 100%, achieving a void-free and moisture-resistant insulation. The special polyester protective cover prevents sticking during unwinding and facilitates handling.

Applications
This adhesive tape is designed for use in electrical installations, particularly in high-voltage systems up to 69 kV. It is suitable for insulating cables, conductors, and connections where a dense, moisture-tight seal is required. Applications include areas demanding high electrical resistance and mechanical flexibility, such as repair or maintenance of high-voltage cables.

Functions and Features in Detail
The tape is made of a self-fusing EPR material that forms a dense, homogeneous layer when applied under pressure and temperature. This property ensures effective insulation without gaps or voids. The material composition is non-vulcanizing, meaning it does not trigger chemical reactions during application that could impair electrical properties. The excellent electrical properties of the material ensure reliable insulation even under load.

Technology Explained Simply
The self-fusing behavior of the EPR material allows the tape to adhere to itself when wound and pressed, forming a closed, dense layer. This is crucial to exclude moisture and humidity, which could lead to corrosion or insulation failure. The elongation of up to 100% allows adaptation to different diameters and surface irregularities, achieving optimal fit. The polyester protective cover prevents the tape from sticking to the roll during unwinding, simplifying handling.

Compatibility and Accessories
The tape is designed for use in electrical systems operating at low and high voltage. It is compatible with various cable types and conductor connections, especially in high-voltage systems up to 69 kV. It is used in conjunction with other insulating or protective materials to ensure complete sealing and insulation. Application typically requires no additional tools, as the tape is activated by hand-winding and pressure.

Installation and Mounting
Installation involves winding the tape onto the area to be insulated, with a recommended overlap of approximately 50% to ensure a dense layer. The tape is wound under slight pressure, activating the self-fusing material to form a closed layer. The polyester protective cover is removed before winding. Application is performed at room temperature, with full curing and fusion achieved through pressure and temperature.

Operational Advantages
The tape provides reliable, void-free insulation that effectively excludes moisture and humidity. High elongation enables adaptation to different geometries, achieving optimal fit and sealing. The non-vulcanizing property ensures no unwanted chemical reactions occur that could impair electrical properties. Excellent electrical properties guarantee stable insulation even under load.

The packaging is a box that protects the tape during transport and storage. The exact dimensions of the tape (19 mm width, 9.15 m length) enable efficient use in various applications. The tape is black, making it suitable for use in electrical installations.
