  • High Dielectric Strength
  • 69 kV Splicing Scope

Product Description

Scotch Linerless Rubber Splicing Tape 130C is a black, linerless self-fusing EPR rubber splicing tape for primary insulation in cable splice and termination work. Its 0.76 +/- 0.076 mm construction combines an ethylene-propylene rubber backing with a fusible adhesive interlayer and is applied in highly stretched, half-lapped layers to build a uniform winding. The tape is rated for 90 deg C operation and 130 deg C emergency overload, with minimum dielectric strength of 27.6 kV/mm under ASTM D4325 test conditions. It is used for supported outdoor and underground electrical connections, including installations up to 69 kV when the specified application method and system conditions are met.

Key features

  • Self-fusing EPR construction: The linerless backing and fusible interlayer combine under stretch to build a uniform insulating wrap.
  • Electrical insulation performance: Minimum dielectric strength is 700 V/mil (27.6 kV/mm) under the stated ASTM D4325 condition.
  • Defined temperature ratings: The tape is rated for 90 deg C operation and 130 deg C emergency overload under ASTM D4388 Type III.

Applications

Applications include primary insulation for cable splices and terminations, plus supported outdoor and underground electrical connections in installations up to 69 kV.

Thermal Properties
Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance. Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.

Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.

Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
27.6 kV/mm
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
