ADSS cable is a very common cable in the market, the technology is very mature. It is the basis of some commonly used parameters in the production and use of ADSS optical cables.

About the electrical performance of 12 - core ADSS cable

The choice of the type of 12-core ADSS cable should first consider the requirements of electrical performance, that is, the size of the space electric field (potential) that 12-core ADSS can withstand.

This is because the 12-core ADSS cable works in the vicinity of the high voltage line, the space around it is electromagnetic field, the capacitance coupling between the cable and the cable makes the cable in a space potential position, fog, dew point or light rain, wet dirt in the cable outer sheath surface formed a layer of resistance.

When the space potential effect, the surface of the sheath on the tower cable grounding metal current flow, generate current heating, resulting in water vapor evaporation, in the surface of the outer sheath of the optical fiber cable formed a small section of dry ground, blocking the current.

When the potential difference of the dry belt reaches a certain height, it will produce an arc, which is called the dry belt arc. The heat generated by the crosslinked polymer gradually loses its binding force, forming corrosion and fusible holes in the sheath. Such faults are called sheath corrosion or electrical marks, and in severe cases can cause cable breakage.

What kind of outer sheath to use for 12-core ADSS depends on the spatial potential of installation position, and is related to the voltage level of power line, tower structure, conductor arrangement, phase arrangement and other factors.
