ScotchTM 23
All-Voltage Splicing Tape

ScotchTM 23 Electrical Tape is a highly conformable self-fusing EPR (Ethylene Propylene Rubber) based, high voltage splicing tape. It is a non-vulcanising, shelf-stable tape with excellent electrical properties. 23 Tape can be used as an insulation for low-voltage applications as well as an insulation for splices up to 69kV.

APPLICATION

  •  Primary electrical insulation for splicing cable from 600V to 69kV on all solid dielectric cables.
  •  Primary insulation for building stress cones on cables up to 35kV on all solid dielectric cables.
  •  Jacketing on high-voltage splices and terminations.
  •  Moisture sealing electrical connections.
  •  Bus bar insulations.
  •  End sealing high-voltage cables.

Description

ScotchTM 23 Electrical Tape is a highly conformable self-fusing EPR (Ethylene Propylene Rubber) based, high voltage splicing tape. It is a non-vulcanising, shelf-stable tape with excellent electrical properties. 23 Tape can be used as an insulation for low-voltage applications as well as an insulation for splices up to 69kV.

The high-voltage corona-resistant tape must be based on ethylene propylene rubber and be capable of operation at the emergency cable temperature of 130°C (266°F). The tape must be capable of being applied in either the stretched or unstretched condition without any resulting loss in either physical or electrical properties.

The tape must not split, crack, slip or flag when exposed to various environments (indoor and outdoor). The tape must be compatible with all synthetic cable insulations. The tape must have a dissipation factor of less than 5% at 130°C (266°F) and must have a shelf life of 5 years.

Engineering/Architectural Specification

Splicing and terminating solid dielectric cables shall be done in accordance with drawings engineered by the splice material manufacturer such as the 2047 series available from 3M Company. All splices and terminations shall be insulated using ScotchTM Brand 23 Electrical Tape.
