Cable Jointing Solutions for Use with Your Electrical Network

Product Description

When you have an electrical network to maintain, you ned the right tools to keep the network secure and functioning. These include among other things cable joints mostly.

Common types of cable joints

Among cable joints, the medium voltage cable joints have much importance. Most of the common applications come under this category and so one must have a choice of cable joints that are reliable and durable. The common choice for the jointing is cold shrink system or the heat shrink system.

Choice of cold system

It is popular to use cold shrink system for jointing cables in places that have restrictions in space or the use of fire is not allowed. This includes most gas stations, oil refineries, and industries where there is exposure to inflammable oils and gases. One cannot use the heat shrink method here and so one should go with the cold shrink system for jointing the cables.

Need for cable joints

Here we see the need to make cable joints. The cables need regular maintenance since many of them remain exposed to the inclement weather conditions. In certain other places, people want to make extensions to their existing network and so one must use new cables and make cable joints to keep the grid functioning. Medium voltage cable joints are subjected to wear and tear and so you must check them regularly to see that they are proper shape and functioning properly.

Types of cable joints

One may use either the straight through joints or the transition cable joint to make the needed connection. The straight through cable joint will connect two similar cables while the transition cable joints join two dissimilar cables. So, to make a connection between an XLPE and another XLPE cable, you use a straight through joint. Or, if you have a PILC cable and another PILC cable the joint will be straight through. If one of the cables differ from the other, then you use a transition joint.

Choose a heat shrink system

The preference for cold shrink systems is limited only to those areas where you cannot use the heat shrink system. Otherwise, the heat shrink system will give you perfect waterproof and stable joints with a superior mechanical strength. The use of a blow-torch to fuse the sleeve material to the joint makes the joint very secure.

In the cold shrink joints, the sleeve is slipped onto the joint after joining the bare wires. Then the sleeve tightens over the joint due to the preinstalled tension in the sleeve. This helps make the joint secure.

Use superior quality material

You must use excellent quality material to keep the integrity of the network safe. Choose reliable suppliers who deliver superior quality material to give your cables and cable jointing solutions. Many projects are time dependent. So, you must have a supplier who will stick to the delivery schedule and not keep you waiting.

It is necessary to have a reliable standby team who know how to maintain the network. Most of the time, the suppliers will send the people to do the installation and, for a price, they will do the maintenance work too.

Answering All Questions About Advanced Cable Joints

Product Description

The cable joints hold a great functional role in the installation of medium and high voltage cable lines. While the latest technology has made it possible to use polymeric materials in the joints, the manufacturing techniques help a lot in designing the effective products.

If you want to know about the cable joints and its functions, have a look at this article.

 How many types are there?

The types can be defined through factors. One such factor is the installation type, which gives you Medium voltage cable joints with the varieties of heat shrink and cold shrink. Both the types serve different purposes and suit a different set of environments. The engineers select the joints, according to the requirements of the cable system.

 What are the applications of the joints?

The joints are mainly used to join two separate sections of the cables. However, that is not the function they serve. The insulation of the product provides protection in the area of the joint and keep it safe from the pollutants, water contamination, UV rays, and other factors. Apart from the general features, different manufacturers offer other features related to the installation procedure, performance life, and others.

 How are the joints installed on a cable?

Well, it depends on the type of the joint. For instance, if it is a cold shrink one, then, the installation just requires the removal of tubing and slipping into the cable. On the other hand, if the heat shrink joint is being used, then, you will need to use fire to install the joints. The construction of both types makes it easy for the installer to avoid any sort of complication. Even heat shrink ones have become very convenient and can easily be installed with only a little effort.

 Can a joint be installed in every type of cable?

No. The suitability depends on several factors such as the voltage capacity of the cable and the joints, the requirement of the area of application, the number of cores required. Apart from all these things, the installation also depends whether the joint is straight through or a transition one. The match between the product and the cable is necessary in order to get the right functioning of the cable lines.

This device is a necessary part of the power industry. No steps can be taken if this accessory is not there. The joints are reasons why we are able to set long power lines and provide energy to remote areas. Hence, it becomes important that the engineers make sure that the cables get suitable accessories. It will allow them to get maximum performance out of the power lines for a long period of time. The manufacturers offering these products provide assistance in installation, which should not be neglected.

So, all you need to do is get the suitable product for your cable lines from a renowned manufacturer and allow the manufacturer to assist you in the installation. The manual provided by the company is a must read before installing the joints.
