Five factors affecting the quality of Heat Shrinkable Insulation Tube

2022-07-08
With the development of production technology and the improvement of standards of domestic and foreign enterprises, the quality of Heat Shrinkable Insulation Tube has been put forward higher requirements. As a kind of common insulating tube, Heat Shrinkable Insulation Tube has become an important part of electrical and electrician all over the world. How to select high quality Heat Shrinkable Insulation Tube has become the theme of today, the following five factors affecting the quality of Heat Shrinkable Insulation Tube are provided:

1. Electrical performance: the quality of electrical performance is the first principle to judge the quality of Heat Shrinkable Insulation Tube, mainly considering whether the distribution of insulating electric field is reasonable, whether the improvement of electric field measures are consistent, the electrical strength of the material, cut-off loss and insulation grade of the product, etc. We also need to consider the stability of electrical properties, including the physical properties of insulation and structural stability. Most Heat Shrinkable Insulation Tube are usually rated at 600V, and the rated voltage of the 10kV and 35kV Bus-bar Tube can reach 10-35kV.



2. Sealing performance: Sealing moistureproof is an essential performance of Heat Shrinkable Insulation Tube, which directly affects the electrical performance and service life of Heat Shrinkable Insulation Tube protection products. Sealing structure must be stable, stable performance. Heat Shrinkable Insulation Tube are wrapped in cables and buried directly in damp conditions, so Heat Shrinkable Insulation Tube must be well sealed against moisture.

3. Mechanical properties: As the protective layer of the cable, the Heat Shrinkable Insulation Tube should have the mechanical properties of wear resistance, softness, bending resistance and impact resistance. Should withstand a certain tension and the ability to prevent external damage, such as: prevent mice and other small animals damage and other external damage.

4. Chemical performance: Heat Shrinkable Insulation Tube is usually used as the solder joint insulation protection of the cable. The use environment of the cable is very complex, and it can not be used directly only after passing the performance test of the mechanical equipment.

5. Process performance: Installation process and material manufacturing process are important conditions for selecting Heat Shrinkable Insulation Tube. The installation process should be as simple as possible, convenient for on-site construction, the technical requirements of the construction personnel should not be too high, the construction environment is not picky, the installation quality is controllable, the quality is reliable.
