Structure and characteristics of self-supporting cable





The self-supporting cable is designed as a set of several insulated conductors that are tied together.
 This design allows the cables to be installed aerially and on the masts. The XLPE insulation used
 in these cables is known as a high-quality insulation that has excellent resistance to heat
 and weather conditions.

The aluminum conductor used in the self-supporting cable is a suitable option for this type
 of cable due to its light weight and high conductivity. These features make the installation
 and transfer of these cables easier and faster.  Also, the presence of a holding wire in them
 helps to stabilize the cables at the installation site and reduce mechanical stress.
 This issue leads to increasing the durability and lifespan of the cables.

The self-supporting cable usually consists of two or more insulated phase conductors, which are generally
 made of aluminum or copper. Aluminum is a popular choice for making conductors due to its light weight
 and good conductivity. In fact, aluminum conductors are not only more economical, but also more resistant
 to rust and atmospheric factors. Copper is also used as a conductor with higher conductivity 
in some special applications.
