Ⅱ. FeaturesHeat Shrink Cable Joint Kit
1. Low tension
Heat shrink cable joint kit uses high-standard heat-shrink material to ensure the best performing electrical insulation at low tension avoiding all types of electrical faults and short circuits. The material has high mechanical strength against all types of mechanical stresses that may be induced during the working of a cable, on the path of the run, maintaining stability and extending durability in the joint.
2. Weather Resistance
It is highly weather-resistant and also protects against UV, making it possible for outdoor usage for a long period of time, reducing material aging and performance degradation due to any environmental factors.
3. Easy Installation
It has a streamlined design, thus allowing quick and easy installation, perfectly fitting in tight spaces, hence drastically reducing installation time and costs.
4. Customization Services
Offer LV heat shrink cable joint kit solutions customization to conform with specific needs in different scenarios of applications.
