Three benefits of our insulation material
Reliable protection, always fitting
Our insulation sleeves protect against electrical flashover, heat, and mechanical damage. Suitable for bundles, pass-throughs, or individual conductors, in any installation situation.
Always have the right specification at hand
Easily choose from transparent, halogen-free, shrinkable, or self-extinguishing sleeves. You work according to regulations and with the correct insulation thickness for your cable type and environment.
Quickly processed, neatly finished
Due to the flexible structure and variants on rolls, per meter, or in sets, you install efficiently without kinks or waste. Ideal for both prefab and retrofit applications.
What do our customers say?
Which insulation sleeve suits your installation?
A good insulation sleeve protects cables from heat, wear and electrical breakdown. Whether you work in a panel, machine or industrial installation: the right insulation prevents malfunctions and extends the life of your cabling. Nedelko supplies high-quality insulation sleeves made of materials such as polyolefin, PET and fiberglass, tailored to your application and processing.
- A solution for every environment: high-temperature resistant, halogen-free or self-extinguishing sleeves for electrical engineering, machine construction or vehicle installations.
- Easy to process: choose from shrink sleeves, braided or woven versions, available by roll, by meter or as custom solutions.
- Safety according to standards: materials comply with IEC and UL guidelines for insulation resistance, flame retardancy and electrical resistance.
- Performance materials: from flexible PET to abrasion-resistant fiberglass or polyolefin with high temperature resistance.
- Neat finish without bottlenecks: for bundling, color coding and protection of vulnerable wires or connector transitions.
Insulation sleeves: for electrical safety and sustainable protection
A high-quality insulation sleeve protects more than just your cables. Whether you work with low-voltage lines, high-frequency signals or in an environment with heat or chemicals: the right insulation sleeve prevents short circuits, extends the life of your installation and keeps your bundling organized. Nedelko supplies a complete range of insulation sleeves made of materials such as polyolefin, PET, PTFE and fiberglass, tailored to your application, voltage and environment.
Common risks with unsuitable insulation sleeves:
- Breakdown or short circuit due to insufficient insulation resistance: at high voltages, too low dielectric strength is fatal, with the risk of system failure.
- Melting or fire damage due to incorrect temperature resistance: not every material withstands prolonged heat exposure or sudden peaks.
- Mechanical wear or cracks with movement or bending: stiff or unsuitable sleeves quickly damage in dynamic cable applications.
- Rejection during inspection due to missing marking or standards: without recognizable coding or material classification, you do not meet safety requirements.
- No halogen-free version, unsuitable for public or critical installations: in case of fire, incorrect material can emit toxic fumes.
Why professionals choose insulation sleeves from Nedelko:
- Technical advice down to fiber level: our specialists help you choose based on dielectric strength, shrink ratio and temperature resistance, no guesswork, just certainty.
- Performing versions that last: from halogen-free polyolefins to fiberglass with silicone coating: tested for wear, cracking and electrical insulation value.
- Always the right size, available immediately: from thin bundle sleeves for electronic assembly to thick shrink tubes for industrial main lines, on roll, per meter or per set.
Our experts advise you based on voltage level, temperature range, mechanical stress, insulation value and assembly method. This way, you can be sure that your cables are optimally protected. Now and in the long term against breakdown, wear or rejection during inspection.
