3M Scotch 23 Rubber Splicing Tape* - the heavy-duty one for high voltage.
*What it’s used for:*
1. *High-voltage cable splicing* - Self-fusing rubber tape for insulating splices + terminations on medium/high voltage cables. Bonds to itself, no adhesive needed.
2. *Handles heat + overload* - Made from Ethylene Propylene Rubber EPR. Works on cables that hit 130°C in emergency overload. So it won’t melt when cables get hot.
3. *Moisture + electrical barrier* - Stretches 2x-3x and fuses into one solid rubber layer. Keeps water, dust, electricity from leaking at the joint.
*Who uses it:* HV electricians, power utilities, substations, solar farms, heavy industry. Anywhere you’re joining thick power cables.
*Pro tip:* Always stretch while wrapping, then cover with Super 33+ tape. That’s the 3M "system".
