HELLERMANNTYTON HelaTape Power 750 nastro isolante autoagglomerante, 19 mm x 9,1 m, nero 711-00300

With a dielectric strength exceeding 30 kV/mm, this self-fusing EPR tape delivers reliable primary electrical insulation for low- and medium-voltage applications up to 69 kV.

Overview

HELLERMANNTYTON HelaTape Power 750 is a self-amalgamating rubber tape made of ethylene propylene rubber (EPR). It fuses to itself without adhesive, forming a homogeneous, moisture-tight seal. The tape is black, 19 mm wide, 9.1 m long, and 0.76 mm thick. It operates from -40 °C to +90 °C and withstands short-term overloads up to +130 °C.

What stands out

• Self-fusing: no adhesive residue, bonds only to itself
• High elongation at break (>900%) for conformable wrapping
• Excellent UV and water resistance for outdoor use
• Meets ASTM D-4388 standard for insulating tape
