Sleeves, not insulated

Non-insulated sleeves - a key element of electrical installations

In the world of electrical installations, non-insulated sleeves play an extremely important role.   These inconspicuous elements provide reliable cable connections, ensuring the safety and efficiency of the entire system.   In our daily practice, we see how important it is to select the right sleeves for specific applications. That is why at Onninen we offer a wide range of high-quality products that will meet even the most demanding projects.

Non-insulated sleeves are divided into several basic types. The most common are flat, round and fork sleeves. Each type has its own unique features and applications. Flat ones work well in limited spaces. Round ones provide a secure connection with pins. Fork ones facilitate assembly under screws and bolts.

A wide range of non-insulated sleeves in the Onninen offer

In our catalog you will find products from renowned brands.   We especially recommend sleeves from our own brands: Onnline, FXA and Opal.   These product lines were created with the needs of professionals in mind. They combine high quality workmanship with an attractive price. Many of our customers appreciate their reliability in everyday use.

We offer non-insulated sleeves in various sizes and designs. Copper, brass and steel models are available. Each material has its advantages. Copper is characterized by excellent conductivity. Brass is resistant to corrosion. Steel provides high mechanical strength. The selection of the appropriate type depends on the specifics of the given installation.

• MS untinned wire sleeves
• Sleeves in accordance with DIN 46247
• Flat, round and fork sleeves
• Models with different cross-sections: from 0.5 mm² to 95 mm²

How to choose the right non-insulated sleeves?

Selecting the right non-insulated sleeves is crucial.   A number of factors must be taken into account, such as wire cross-section, material and operating conditions.   We often come across the question of selection criteria. Here are the most important aspects to consider:

• Wire cross-section - must match the sleeve
• Material - adapted to the working environment
• Shape - depends on the type of connector
• Standards - compliance with industry requirements
• Mechanical strength - adequate to the loads

Our experience shows that the right selection of sleeves significantly affects the quality of the installation. Recently, we used Onnline sleeves in a project for a large shopping center. Their high quality and precision of workmanship made installation easier. The result was a reliable installation that has served the customer to this day.

In the case of office reorganization, we most often encounter the need for flexible solutions. Non-insulated sleeves allow for easy modification of cabling. This is especially important in a dynamically changing work environment. Opal fork sleeves have proven to be exceptionally good in such situations.

It is worth remembering that uninsulated sleeves require additional insulation after installation.   Our offer includes a wide selection of heat shrink tubing and insulating tapes. A comprehensive approach to the subject of electrical connections is our specialty. Thanks to this, we can guarantee the safety and durability of the installation.

Many customers ask us about the differences between tinned and untinned sleeves. The latter are more versatile. They work well in most standard applications. We recommend tinned sleeves for environments with increased humidity. The tin layer provides additional protection against corrosion.

At Onninen, we attach great importance to the quality of our products. All non-insulated sleeves in our range undergo rigorous testing. We control their dimensions, strength and conductivity. This ensures that we provide our customers with top-class products.

Non-insulated sleeves are just one element of Onninen's comprehensive offering for the electrical industry.   Our range also includes cables, connectors, switchboards and many others. We provide professional advice at every stage of project implementation. Our experts will be happy to help you choose the optimal solutions.
