Self-fusing, tear-resistant, and easy to install, our silicone fusing tape delivers durable, mess-free insulation with precise kV protection for critical electrical applications
Seal it right - insulate low, medium, and high voltage applications with precision
Power Line Sentry’s self-fusing silicone insulating tape is a high-performance solution engineered for low, medium, and high-voltage applications, providing scalable insulation up to 69kV. Ideal for environments where traditional covers don’t fit, this tape is designed to form a permanent, moisture-resistant barrier around jumper ends, bus connections, insulated line hose terminations, and irregularly shaped electrical components.
Crafted from premium silicone, this tape withstands exposure to oxygen, ozone, UV radiation, and corona discharge, maintaining durability and flexibility across a wide temperature range (–40°C to 175°C). Its self-bonding, non-adhesive design ensures a strong, irreversible seal that leaves no sticky residue, making it the ideal choice for clean, fast, and field-friendly installation.
Each layer of tape provides 15kV phase-to-ground protection, with the ability to scale up to 69kV by adding layers—ensuring reliable insulation in both routine and critical installations. For precise and efficient field use, every roll includes pre-printed guide-lines to simplify installation and deliver accurate kV insulation ratings.
Whether used in substations, overhead lines, or maintenance zones, our fusing tape is the go-to solution for quick, durable, and safe electrical insulation, especially where space constraints or irregular surfaces demand flexible protection.
Where covers don't fit, fusing tape does
-
Self-fusing: creates a permanent, weatherproof insulating seal without adhesives or residue
-
Precision insulation with printed guidelines: pre-marked kV indicators ensure accurate application and proper insulation coverage—fast and field-friendly
-
Clean, irreversible bond: adheres only to itself, leaving no sticky residue on conductors, tools, or hands.
-
Performs in all conditions: reliable sealing and insulation across a wide temperature range for year-round use
-
High voltage protection: delivers up to 15 kV phase-to-ground protection per layer and scales up to 69 kV when layered
-
Perfect for terminations and transitions: ideal for sealing line hose ends, jumper connections, and other irregular shapes or transition points
-
Field-friendly packaging: available in convenient 2″ x 36′ rolls (5cm x 11m) for efficient use in any circumstance
