Genuine 3M Scotch 130C Linerless Rubber Splicing Tape | 69kV High-Voltage Self-Fusing Insulation Tape - STK
STK supplies Genuine 3M Scotch 130C Linerless Rubber Splicing Tape, the premier industrial gold standard for high-voltage electrical insulation and moisture-tight sealing. Formulated from a premium ethylene propylene rubber (EPR) base, this 30-mil (0.762mm) thick, highly conformable tape is engineered to deliver flawless primary insulation for cable splices and terminations rated up to 69kV.
The defining engineering breakthrough of Scotch 130C is its linerless design. By eliminating the annoying plastic or paper backing found on standard rubber tapes, it allows linemen and industrial electricians to wrap high-amp electrical joints faster, tighter, and with zero job-site waste.
Key Features
Self-Fusing Technology Creates Void-Free Insulation
Unlike ordinary electrical tapes, 130C fuses into a homogeneous rubber mass after installation, eliminating air gaps and improving long-term insulation reliability. This makes it ideal for critical medium-voltage and high-voltage cable joints.
01
Primary Insulation for Cables up to 69kV
Specifically designed as primary insulation for solid dielectric cable splices and terminations, providing dependable electrical protection in utility and industrial power systems.
02
Excellent Moisture Sealing Performance
Creates a moisture-proof seal that protects cable connections from water ingress, corrosion, and environmental contamination. Particularly suitable for outdoor installations and underground cable networks.
03
Outstanding Flexibility & Conformability
The EPDM rubber backing easily conforms to irregular surfaces, connectors, busbars, and cable terminations while maintaining electrical integrity.
04
UV & Weather Resistant
Suitable for indoor and outdoor applications where long-term exposure to sunlight, humidity, and temperature fluctuations can degrade conventional tapes.

Primary Heavy-Duty Application Fields
High-Voltage Cable Splicing: Providing primary electrical insulation for splicing and terminating solid dielectric cables rated from 600V up to 69kV.
Outdoor Substation Maintenance: Waterproofing and insulating high-voltage bus bar connections, transformer leads, and outdoor switchgear components.
Subsea & Mining Cable Repair: Creating a heavy-duty, moisture-tight jacket sealing over torn cable sheaths on underground mining equipment and marine conduits.
Moisture-Sealing for Telecom Towers: Wrapping outdoor coaxial cable connectors and ground wire splices on cellular base stations to prevent rainwater corrosion.
B2B Supply Chain Superpower: Custom Sizing & Direct Wholesale Contracts
Large infrastructure tenders and automated manufacturing assemblies require stable pricing, certified traceability, and customized packaging options. STK directly optimizes your logistics pipeline:
Flexible Width Log Slitting
While standard 3/4-inch and 2-inch sizes are always in stock, STK can utilize automated log splitters to slit genuine 3M 130C master rolls into custom widths tailored to your specialized automated wrapping machines or unique industrial housings with pristine, unwrinkled roll edges.
Guaranteed Traceable Fresh Batches
Old rubber tape loses its self-amalgamating properties and turns brittle. STK guarantees fresh, recently manufactured inventory with active factory batch tracking numbers, ensuring maximum physical fusion power upon arrival on your job site.
Tiered Commercial Contract Pricing
We offer aggressive, volume-tiered wholesale contract pricing for utility companies, international electrical distributors, and major engineering contractors.
