Jiangsu New Xinghai Special cable Technology

First, the characteristics of THE ADSS fiber optic cable are as follows:
(1) designed for the power system, is a full insulating medium of self-contained overhead fiber optic cable, its structure does not contain any metal material;
(2) The full insulation structure and high pressure-resistant index are conducive to the installation and construction on the overhead power line running with electricity, and do not affect the operation of the line;
(3) the use of anti-pull strength of high anti-corrosion material, that is, can withstand strong tension, to meet the large span requirements of overhead power lines, but also to prevent bird and human shooting;
(4) ADSS fiber optic cable thermal expansion coefficient is small, in the temperature change is very large, the arc of the fiber optic cable line change is very small, and its weight is light, its ice and air load is also small.
Second, the service life of ADSS fiber optic cable
ADSS fiber optic cable is installed on high-voltage transmission lines, its general life is more than 25 years, and there are many factors affecting its life.
The main factors are: (1) The gradient of the high-voltage induction electric field near the pole tower is large, and the high-voltage induction electric field has strong electrical corrosion on the fiber optic cable.
General KV and the following overhead power lines with PE type, 110KV and above line with AT type;
(2) For the pole tower of the double circuit, due to the circuit of the line power failure or line modification, in the selection of hanging points to be considered;
(3) When the line passes through the working area with hydrochloric acid gas, the chemical substances will corrode the outer skin of the fiber optic cable, and its electric protective sleeve is damaged, which is vulnerable to the damage of the arc; (4) Improper construction caused skin damage or wear, etc., in the long-term high-voltage electric field operation, its surface is easy to corrode, and the outer sheath flat smooth fiber optic cable can effectively reduce electrical corrosion and extend the life.
