Transformer Shrink Tape

Transformer Shrink Tape is a professional heat-shrinkable sealing tape constructed from polyester fiber; engineered for reliable insulation and sealing in harsh environments. Unlike conventional adhesive-based electrical tapes, it uniformly shrinks when heated, creating a tight physical wrap around irregular shapes and complex components for a seamless, permanent seal. With excellent resistance to moisture, chemicals, and mechanical stress, it is the ideal choice for mission-critical installations where reliability is essential.

Performances
It features high tensile strength, providing firm and slack-free binding. It shrinks uniformly upon heating (shrinkage rate up to 10%-40%), tightly wrapping around irregular components to form a gapless physical seal. Its heat resistance rating reaches Class F (155°C) to Class H (180°C), allowing long-term use in transformer oil. It offers excellent electrical insulation performance with no breakdown or flashover, while remaining non-contaminating to transformer oil and resistant to chemicals and aging.
