Evaluating the Accessories for LV ABC (Aerial Bundled Conductor) Cables
It is important you are aware of the fact that Aerial Bundle Cable (ABC Cable) is quite an innovative product, just as it is featured on Marel, most especially for overhead power distribution as it is compared to the regular bare conductor overhead distribution system. It provides lower power losses, a higher level of reliability and safety, and ultimate system economy by reducing the operation cost, installation cost, and the maintenance cost.
Aerial Bundled cables (which can simply be referred to as ABC or aerial bundled conductors) are nothing other than overhead power lines that make use of a number of insulated phase conductors merged tightly together, most times with a simple neutral conductor. This compares with the conventional practice of using insulated conductors that are separated using air gaps. This difference of overhead power lines makes use of the principles as bundled conductors, if and only if they are close together to the point of touching but having each conductor surrounded by an insulating layer.
The main objections to the conventional design are that the multiple conductors are seen to be unappealing, and secondary forces like high winds can be one of the reasons they touch and eventually short circuit. The resulting spark from the contact has resulted in a number of bushfires in dry climate areas. In the United Kingdom for instance where some supplies to rural properties are concerted to MEN/PME from TT Earthing system, worries have been expressed that there high vehicle or falling tree might be one the reasons that the low conductor got broken, still leaving the upper phase conductor in place.
Choosing an ADSS fiber optic cable and the accessories that it has can be hard. After all, a lot of factors can affect your choice of which accessories to purchase for those ADSS accessories. So you will need to consider so many things, such as the location of those ADSS cables. Where will our fiber optic cable be installed, by PVC or metallic pipe, aerial or direct buried? There are several types of fiber optic cable for both indoor and outdoor, below are the characteristics and applications that cover each need.
This cable is generally used for the distribution or expansion of a network in which it is necessary to go from one floor to another or in many cases from one building to another, taking into account that care must be taken when installing, in addition to other conditions such as: Ductwork: PVC, Metallic or Concrete. Registers: Voltage or Slack Cable.
And those are but a few of the factors that you will need to take into consideration when looking at ADSS accessories. So if you need an overview of the different choices that you will need to make, here they are.
The development of the different types of ADSS fiber optic cable for long distance runs generated a new revolution in the world of telecommunications similar to that which at the time meant the introduction of fiber optics.
The fiber optic cables for overhead lines, in their different conformations but especially those that can be installed in high voltage lines, have been highlighted as systems suitable for the transmission of communications.
It is a completely dielectric cable, with a special armor that allows it to cover large spans, which is installed at the height of the crossheads of the high voltage lines, separated from the conductors. Its laying can be done without any need to interrupt the electric service.
Features of these ADSS cables:
The ADSS cable eliminated the need for a messenger, thus constituting an excellent solution for long distances.
This type of cables can be manufactured with a maximum amount of 864 fibers depending on the span length (span). The span that the cable can cover is up to 1000 meters.
Thanks to the fact that they do not contain any metal element in their construction, the weight per kilometer is reduced, which makes the installation easier.
This variant of cable has a protection against humidity, this protection is called Fortex, or failing in some other cables is a gel.
With its innovative design dielectric cables can accommodate a certain amount of fibers and its cable diameter can be only 9-10 mm which makes it have great versatility in small spaces.
The design of the cable can offer a weight per km of only 92 kg, which facilitates its installation and transport.
It can be used in aerial installations with the lash system and in installations made of metal ducts or PVC.
Its loose tube construction allows the fibers to remain stress-free in their operating range.
They are easy to install and reduce costs, built with the durable polymer.
