Spiral Tube for Electric Insulation

Unlike the process of molding it into a straw-shape using an extrusion machine, we’ve slit the industrial insulation film into a tape condition and adhered and solidified it into a spiral shape.

Features

While it is difficult for to create the Super heat resistant material in extrusion, we are able to make it from starting from one tube.
On top of that, we can cope with different composite multi-layered film such as PET and PPS, which lets us take a step ahead from what we thought it was impossible to do.

Our trust we’ve developed for 40 years let us expand into different fields

Although we primarily focus on the insulator or the wiring lead, we have relations is the fields of…

Automotive

Electricals, Hydrogen automobile motor, Insulator of the lead wire, Transformer, electrical-related lead insulator
Cover for the antenna (that has noise suppression function kneaded into it)

Home appliances

Air-conditioner, Lead wire insulator of motors and such

Aerospace

Insulator in the space satellite that can withstand high temperature heat

Method

Spiral tube for electric insulation is manufactured by slitting insulation films to make it into 2 to 3 types of tape. After that, as the design on the left shows, it is adhered and solidified it into a spiral shape using appropriate heat and glue.

Nitto’s Insulation Tube

Manufacturing Since 1985

We, Nitto Industrial Corporation, are the pioneers of spiral insulation tube.
From making a general insulator, to processing of battery elements and power-saving products, we work for a wide range of electronic and electrical industry to support the lives of the people.

Nitto Insulator Tube/ Spiral Tube

The name “insulation tube” came from the straw-looking shape of the insulator piece that was made to insulate the connector of the electrical connection, and by making the insulation tube into a spiral shape, it is available in fast delivery and in small sets.

Advantages of the Spiral Shape

By making the insulation tube into a spiral shape, we made it unnecessary for going through the process of molding it into a cast.

We now are accepting orders starting from one unit, which we make as soon as the orders are made. Additionally, our products are available in different and wide range of materials to answer to all the needs of our customers.

From our developed skills, we are able to create in different sizes, materials, and for different needs.
We believe our creation of products that take advantages of the features that films has are infinite.
