SN heat shrink tubing - a versatile solution for professionals

SN heat shrink tubing is an indispensable element in the arsenal of every electrician and installer.   At Onninen, we understand our customers' needs in this area perfectly. We offer a wide range of top quality MV heat shrink tubing. Our products meet the strictest industry standards. They guarantee reliable and durable electrical connections. They are suitable for a variety of industrial and domestic applications.

SN heat shrink tubes are not only about protecting wires. They are also an aesthetic finish to electrical installations. They provide insulation and protection against moisture. They protect against mechanical damage. They make it easier to identify wires thanks to different colors. In our offer you will find tubes of different diameters and lengths. Both black and colored variants are available.

SN Heat Shrink Tubing - Key Features and Applications

SN heat shrink tubes are characterized by exceptional flexibility and durability.   They are resistant to extreme temperatures and chemicals. They provide excellent electrical insulation. They protect against corrosion and UV radiation. They are used in many industrial sectors. They are useful in automotive, electronics and telecommunications. They are irreplaceable in the production of household appliances and RTV devices.

In our daily practice, we see a growing demand for these products. SN heat shrink tubing is a standard in modern electrical installations. It helps to keep control cabinets tidy. It secures connections in difficult environmental conditions. It facilitates repairs and modernization of existing installations.

  • Protection of cables against mechanical damage
  • Electrical and thermal insulation
  • Protection against moisture and corrosion
  • Identification and organization of cabling
  • Aesthetic finishing of the installation

Selection of SN heat shrink tubing - what to pay attention to?

Selecting the right SN heat shrink tubing requires taking several key factors into consideration.   The most important parameter is the shrink ratio. It determines how many times the diameter of the tube will decrease after heating. Standard tubes have a ratio of 2:1. For more demanding applications, we recommend tubes with a ratio of 3:1 or even 4:1.

Another important aspect is the operating temperature. Our SN heat shrink tubes withstand temperatures from -55°C to +125°C. We offer special variants for extreme conditions. They withstand up to +200°C. The thickness of the tube wall is also important. It affects mechanical strength and electrical insulation.

At Onninen we offer SN heat shrink tubing from renowned manufacturers. Among them are our own brands: Onnline and FXA. They guarantee an excellent price-quality ratio. For the most demanding customers we recommend 3M brand products. They are distinguished by the highest technical parameters.

  1. Determine the required shrinkage factor
  2. Check the operating temperature in the target application
  3. Choose the right wall thickness
  4. Match the color to your identification needs
  5. Take into account special requirements (e.g. chemical resistance)

SN heat shrink tubing in practice - application examples

SN heat shrink tubes are widely used in various industries and applications.   In the automotive industry, they are used to protect wiring harnesses. They protect the electrical system from moisture and vibration. In electronics, SN tubes are used to insulate soldered joints. They provide protection against short circuits and oxidation.

We recently used SRBB tubes in a project for a large logistics center. They were used to mark and secure cables in switchboards. This resulted in a clear and orderly installation layout. This facilitated later maintenance and any modifications.

In the case of office reorganization, we most often use SRAT tubes. They are ideal for quick and aesthetic organization of cabling. They allow for easy grouping and identification of cables. This significantly improves the work when moving computer stations.

SN heat shrink tubing also works well in difficult outdoor conditions. We use them to secure connections in photovoltaic installations. They protect against moisture and UV radiation. They ensure long-term system reliability.
