Application Overview

Crepe paper tubes are primarily used as electrical insulation components in transformers, where they serve as insulating sleeves for conductors and diverters. Their flexibility and dielectric performance make them suitable for:

Distribution transformers
Power transformers
Traction transformers
High‑voltage diverter insulation

The tubes are optimized for oil‑filled environments and demanding operating conditions commonly found in transformer construction and refurbishment.

What We Solve For

In high‑voltage transformer designs, maintaining reliable insulation around conductors and diverters is critical to preventing electrical breakdown and extending equipment life. Crepe paper tubes solve this by providing:

Consistent electrical insulation in tight or irregular geometries
Materials compatible with transformer oils and liquid dielectrics
Thermal performance aligned with Class A insulation requirements
A standardized, IEC‑compliant insulation solution for manufacturers and service providers

This helps reduce failure risk, simplify installation, and ensure compliance with international insulation standards.
