Insulation Crepe Paper Tubes For Transformer

Insulation Crepe Paper Tubes For Transformer

Crepe paper tubes are made from electrical insulation crepe paper formed into tubular shapes. Crepe paper tubes are flexible electrical insulation tubes mainly used in oil-filled transformers for lead insulation, conductor covering and internal insulation support.

What Are Crepe Paper Tubes?

Crepe paper tubes are tubular insulation components produced from electrical crepe paper. They are mainly used inside transformers to insulate leads, cover conductors and protect internal wiring paths.

In practical transformer work, not every insulation point is flat or easy to cover with rigid materials. Some areas require a flexible tube that can:

• bend with the lead path

• adapt to irregular shapes

• remain compatible with the oil-paper insulation system

• provide reliable insulation during long-term service

This is where crepe paper tubes are commonly used.

Key Advantages of Insulation Crepe Paper Tubes:

1. Proven Dielectric Strength: Provides proven high insulation strength, a key material for transformer lead insulation.

2. Superior Flexibility & Durability: Unique transverse wrinkling and spiral winding processes give it excellent flexibility and mechanical durability, allowing it to bend without collapsing under extreme conditions.

3. Exceptional Oil Compatibility: Highly compatible with liquid insulating media (transformer oil), the wrinkled structure maximizes the absorption and retention of insulating oil.

4. Customizable Processing: Slit rolls are available to customer-required widths for easy field installation and flexible application.

Typical Specification:

Insulation Class: Class A (105°C)

Adhesive applied only to the outer edges to ensure structural integrity and unobstructed internal oil passages.

FAQ

Q1: What are crepe paper tubes used for?

A: Crepe paper tubes are mainly used for transformer lead insulation, conductor covering and internal insulation support.

Q2:Are crepe paper tubes suitable for oil-filled transformers?

A: Yes. They are widely used in oil-filled transformer insulation systems.

Q3: Why use crepe paper tubes instead of rigid tubes?

A: Because crepe paper tubes are more flexible and easier to fit around curved leads and irregular insulation points.
