APKT 1: How to Achieve Unsurpassed Performance in Polluted and Desert Environments with Raychem's Heat-Shrinkable Terminations


What is APKT 1 and why you should know about it




If you are looking for a reliable and easy way to terminate medium voltage cables, you might want to check out APKT 1. This is a heat-shrinkable termination that can be used for polymeric and MIND paper insulated cables from 7.2 kV up to 40.5 kV. It is designed by TE Connectivity, a global leader in connectivity and sensor solutions.


But what exactly is a heat-shrinkable termination and how does it work? And what are the advantages of using APKT 1 over other termination options? Moreover, what if you need to download some third-party apps that are not available in the official app stores? Is there a way to do that safely and conveniently?

In this article, we will answer these questions and more. We will explain what APKT 1 is, how to install it, and how it compares with other terminations. We will also introduce you to APKTime, an app store that offers all the latest and most popular APK files for Android devices. We will show you how to download and install APKTime, and how it compares with other app stores.


By the end of this article, you will have a better understanding of APKT 1 and APKTime, and why you should know about them. So let's get started!


APKT 1: A heat-shrinkable termination for medium voltage cables




A heat-shrinkable termination is a type of cable accessory that is used to connect a cable to an equipment or another cable. It consists of a heat-shrinkable tubing that covers the exposed conductor and insulation of the cable, providing electrical insulation, mechanical protection, and environmental sealing.


APKT 1 is a heat-shrinkable termination that is specially designed for medium voltage cables from 7.2 kV up to 40.5 kV. It can be used for polymeric and MIND paper insulated cables, as well as for single-core, three-core, armored, and unarmored cables. It is made by TE Connectivity, which has over three decades of experience in developing reliable cable terminations.


Some of the benefits of using APKT 1 are:


  • It provides excellent environmental protection with its red non-tracking HVOT tubing that resists erosion, UV radiation, moisture, pollution, and chemicals.



  • It reduces installation time by eliminating the need for penciling or removing the insulation from the cable.



  • It has enhanced range-taking ability with its spiral adhesive coating that adapts to different cable diameters and shapes.



  • It has improved electrical performance with its stress control mastic that reduces the electrical stress at the cable termination.



  • It has a long service life with its high-quality materials and proven design that meet the international standards such as IEC, IEEE, and VDE.



Features and applications of APKT 1




APKT 1 is a versatile heat-shrinkable termination that can be used for various types of medium voltage cables and applications. Some of the key features and applications of APKT 1 are:


Feature


Application


Red non-tracking HVOT tubing


Provides environmental protection and color coding for indoor and outdoor terminations


Spiral adhesive coating


Ensures a tight fit and a good seal for different cable diameters and shapes


Stress control mastic


Reduces the electrical stress at the cable termination and prevents partial discharge and corona


Yellow stress control tubing


Provides additional stress control and insulation for the cable conductor


Black insulation tubing


Provides electrical insulation and mechanical protection for the cable insulation


Metallic mesh tape


Provides a continuous earth connection for armored cables


Copper lug or ferrule


Provides a secure connection for the cable conductor to the equipment or another cable


Rain shed or skirt


Provides extra protection against moisture and pollution for outdoor terminations


How to install APKT 1




Installing APKT 1 is a simple and quick process that can be done by following these steps:


  • Cut the cable to the required length and strip off the outer sheath, armor, and inner sheath according to the dimensions given in the installation instructions.



  • Slide the red HVOT tubing over the cable and position it at the end of the cable insulation.



  • Apply the stress control mastic over the exposed conductor and insulation, making sure to cover the entire surface evenly.



  • Slide the yellow stress control tubing over the mastic and position it at the end of the cable insulation.



  • Slide the black insulation tubing over the yellow tubing and position it at the end of the cable insulation.



  • If the cable is armored, wrap the metallic mesh tape around the armor and secure it with a cable tie.



  • Crimp or solder the copper lug or ferrule to the cable conductor according to the manufacturer's specifications.



  • Connect the lug or ferrule to the equipment or another cable using a suitable bolt or connector.



  • Apply heat to the red HVOT tubing using a gas torch, starting from the lug or ferrule and moving towards the cable. The tubing will shrink and adhere to the cable, forming a tight seal.



  • If the termination is for outdoor use, slide the rain shed or skirt over the red HVOT tubing and position it at a suitable distance from the lug or ferrule. Apply heat to the rain shed or skirt until it shrinks and adheres to the tubing.



Comparison of APKT 1 with other termination options




APKT 1 is not the only termination option available for medium voltage cables. There are also other types of terminations such as cold-shrinkable, pre-molded, and epoxy resin terminations. How does APKT 1 compare with these options in terms of performance, cost, and ease of installation?
