Criteria for selecting medium voltage cable joints and terminations

Choosing the right sleeve or head is a key issue. It affects the safety and efficiency of the installation. When choosing, several important factors should be considered:

• Nominal network voltage
• Cable cross-section and type
• Environmental conditions of installation
• Installation requirements
• Compatibility with existing infrastructure

Our experience shows that precise selection is crucial.   It helps avoid problems in the future. It ensures long-term and trouble-free operation of the network. At Onninen we provide expert advice in this area.

We often come across questions about joints for cables of different cross-sections. This is a common situation when modernizing networks. In such cases, we recommend special transition joints. They provide a safe connection of cables of different parameters.

Practical applications of MV cable joints and terminations

Medium voltage cable joints and heads are widely used. They are used in various energy projects. Here are some examples from our practice:

We recently participated in a project for a large industrial park. We used XLPE through-joints there. This allowed for the effective connection of long cable sections. In another case, during the modernization of the city network, interior heads were used. They proved to be excellent in the limited spaces of transformer stations.

For overhead installations, we recommend overhead heads.   They are resistant to harsh weather conditions. They provide reliable operation for many years. Gel sleeves are suitable for underground connections. They guarantee excellent insulation and protection against moisture.

It is worth mentioning the sets for 1 core and 3-phase for 3 1-core cables. They are increasingly used in modern installations. They provide flexibility and ease of installation. This solution is particularly appreciated by installers.

At Onninen we also offer additional accessories. These include screw cable lugs or screened surge arresters. These elements provide comprehensive protection for the installation.

Medium voltage cable joints and terminations are key elements of modern networks. Their correct selection and installation guarantee safety and efficiency. At Onninen we offer not only products, but also professional advice. We invite you to contact our specialists. We will help you choose the optimal solutions for your projects.
