Medium Voltage Cable Accessories and End Caps: Everything You Need to Know

Medium voltage cables are used for power transmission and distribution in various industries such as energy, construction, and transportation. These cables come in different sizes and types and are designed to handle high voltage levels safely and efficiently. However, to ensure the proper functioning and longevity of these cables, it is important to use high-quality cable accessories and end caps.

In this article, we will discuss medium-voltage cable accessories and end caps, and how they play a critical role in protecting and maintaining medium-voltage cables.

Medium Voltage Cable Accessories

Medium voltage cable accessories are used to connect, terminate, splice, and protect medium voltage cables. These accessories are designed to provide a high level of performance, reliability, and safety, and are tested to meet industry standards and regulations.

Here are some of the most commonly used medium voltage cable accessories:

Cable Terminations: Cable terminations are used to connect medium voltage cables to various equipment such as transformers, switchgear, and motors. These terminations provide a safe and reliable connection between the cable and the equipment and protect the cable from environmental factors such as moisture, heat, and UV rays.

Cable Joints: Cable jointing Kits are used to splice two or more medium-voltage cables together. These joints provide a seamless connection between the cables and maintain the electrical and mechanical properties of the cables. Cable joints are typically used in underground applications, where cables need to be spliced to reach a particular destination.

Cable Glands: Cable glands are used to secure and seal medium voltage cables to equipment and enclosures. These glands provide a tight seal that prevents moisture, dust, and other contaminants from entering the cable or equipment.

Cable Markers: Cable markers are used to identify and label medium voltage cables. These markers provide a clear and concise labeling system that helps operators to easily identify and locate cables, which is especially useful in large installations.

End Caps

End caps are used to protect the exposed ends of medium voltage cables from environmental factors such as moisture, dust, and UV rays. These caps provide a seal that prevents contaminants from entering the cable and also protects the cable from physical damage.

Here are some of the most commonly used end caps:

Heat Shrink End Caps: Heat shrink end caps are made from a special type of polymer that shrinks when exposed to heat. These caps are placed over the exposed end of the cable, and then heated to create a tight seal around the cable. Heat Shrink Termination end caps provide excellent protection against moisture, dust, and UV rays, and are commonly used in outdoor applications.

Cold Shrink End Caps: Cold shrink end caps are similar to heat shrink end caps, but do not require heat to create a tight seal. Instead, these caps are pre-expanded and then placed over the exposed end of the cable. As the cap warms up to ambient temperature, it contracts and creates a tight seal around the cable. Cold shrink end caps are easy to install and provide reliable protection against environmental factors.

Injection Moulded End Caps: Injection moulded end caps are made from a high-quality polymer that is injected into a mold to create a custom fit for the cable. These caps provide a tight seal that prevents moisture, dust, and other contaminants from entering the cable, and also protects the cable from physical damage.
